A WORD FROM THE PRESIDENT

The PESGB and Energy Transition … Earlier this year (July edition of the PESGB Magazine) I wrote about the challenges that faced the oil and gas industry, in particular the younger members of our profession whose skills sets will need to evolve and adapt as an inevitable energy transition occurs. Although the article was written to promote support for the younger cohort of our Society, it did attract criticism that I was being too acceptant of the arguments being made in support of anthropogenic climate change. This was not my intent. Having entered the industry in the mid-1980s and been fortunate to remain in continuous employment, I am proud of the role and contribution petroleum geoscientists and engineers have made to ensure that a seamless supply of energy has continued to meet global demands. Indeed, fossil fuels provide around 80% of the current world energy demand. Closer to home, natural gas production forecasts made by

the Oil and Gas Authority for the UK Continental Shelf, indicate the UK would be reliant upon imported gas to meet 86% of demand by 2050. Such a level of imports represents a significant increase from today where 50% of the UK’s natural gas is imported. This transition already represents a considerable change to the industry I joined. Nevertheless, rumours that geoscientists belong to a dying profession are grossly exaggerated! That is not to say that, because the demand for energy will continue, the geoscience community should not have a role to play and a contribution to make as the energy transition takes place. There will continue to be opportunities in traditional petroleum science, whilst new initiatives such as Carbon Capture and Storage are piloted. Academics that include Jon Gluyas at Durham University (Energy Institute) are leading the development of analytical models that address fluid

The PESGB will endeavour to support its membership through jointly hosted events with affiliated organisations to facilitate the issues attached to a future energy transition.

migration and trapping in the subsurface – expertise that is familiar to geoscientists working in petroleum exploration and production. There has been a lot of emotive discussion surrounding the politics and science of anthropogenic climate change. The PESGB has not and will not engage in the public debate. Instead, rather than challenge these issues, the PESGB has a role “… to promote, for the public benefit, education in the scientific and technical aspects of petroleum exploration”. The PESGB will endeavour to support its membership through jointly hosted events with affiliated organisations to facilitate the issues attached to a future energy transition. These are at an early stage of development but will endeavour to address the triggers that will pace a prospective energy transition and the industry opportunities that may emerge. These events will also examine what the future may look like for petroleum geoscientists and how they can position themselves to contribute to, and benefit from, the changes taking place within our industry. This will address not only the individual but also the corporate perspective. The PESGB will continue to provide an update with regard to supporting its membership during the energy transition. In the meantime, I thought I could finish with a quote from John F. Kennedy: “Change is the law of life and those who look only to the past or present are certain to miss the future”.

The Cambo Field West of Shetland Appraisal and Future Development With Kevin Purvis, Katie Overshott, Christian Ellis, Jon Ashdown Siccar Point Energy & Shaun Bambridge, Axis Well Technology

Figure 1: Cambo Field General Location map

The Cambo Field is located on the UKCS in Quad 204 West of Shetland (WOS) and is operated by Siccar Point Energy Ltd with Partner Shell UK. The field was discovered in 2002 by well 204/10-1 drilled by a licence group comprising Hess, Chevron, DONG and OMV. The field was appraised by four subsequent penetrations from 2004 to 2012, with each adding incremental knowledge about the field, but not sufficient to reduce the uncertainty to a level that resulted in field development sanction. Consequently, Cambo has remained one of the major undeveloped discoveries West of Shetland (WOS) with a STOIIP of ~800MMbbls. The inability to test the reservoir in the 204/10a-4z horizontal section in 2012 as a consequence of weather and operational constraints resulted in many of the partners leaving the licence. In 2017 Siccar Point Energy acquired OMV UK, and operatorship of the Cambo licence, an asset that the

company saw as stranded but with a potential route to development. The main reservoirs are the sandstones of the Palaeocene Hildasay Member of the Flett Formation that rest upon the volcanics of the Colsay Member. The Hildasay sediments were deposited in a paralic setting and comprise a suite of estuarine, deltaic, shoreface and fluvial sandstones with interbedded coals and shales. The field structure is a gentle low relief anticline that has a basement high in the southern part of the field. The reservoir units are relatively thin (5-20m) but laterally extensive and comprise excellent quality sandstones (+30% porosity, multi-Darcy permeability). Oil quality is variable as a consequence of differential biodegradation and recharge with viscosities ranging from 5-10cP. The thin nature of the reservoir units and variable oil quality meant that there was an inherent uncertainty in the connectivity of the system, one of the major issues that was addressed

8 PESGB November 2019

by further appraisal of the field. In 2018 Siccar Point Energy, with partner Shell UK, drilled an appraisal well that comprised a pilot hole and a horizontal section that was completed for an EWT. Core data obtained established excellent reservoir quality, with fluid samples confirming the oil distribution in the different units. The well was placed on test and flowed naturally at rates of ~5000 bbls/d of dry oil. Analysis of the well test results show that the reservoir is connected to several hundred million barrels of fluid. Based on the well results the partnership has positive expectations for well rates and recoveries. Ongoing analysis of the samples recovered are further helping reduce the subsurface uncertainty and moving the field towards development. With FPSO and FEED commencing in 2019 the partnership is looking forward to the sanction of a significant development WOS.

The Neglected Reefs of The Zechstein Haupt Dolomite Future Exploration Target With Peter Browning-Stamp, Geoscientist Ardent Oil

The Zechstein (Z2 Cycle) Haupt Dolomite has for many years been a forgotten and neglected exploration target In the UK Offshore, despite successful production from other areas of the Southern Permian Basin, including Onshore in the UK. There are a number of reasons for this. Since the earliest days of Southern North Sea exploration, the play has been overshadowed by drilling campaigns focussed on Rotliegend, Bunter and deeper Carboniferous targets. This is not hard to understand, given the early impetus of UK explorers hunting the next Groningen Field, mapping sizeable prospects, even in those days, on early 2D seismic data. Vastly improved seismic over the years then led to a ceaseless stream of prospects mapped at these target levels, and the reservoirs, by comparison with the fickleness of Zechstein carbonates, were very user friendly. From the earliest wells however, encouragement was there to find within the Zechstein carbonates if you looked for it, with tantalising shows, porosity and several discoveries. Detailed palaeogeographies were however little understood, a situation not helped by the diagenetic overprint on the original depositional environment, and a general lack of core data to study. Notwithstanding this, Ardent Oil have constructed palaeographical maps for the Zechstein, and it immediately becomes clear that the â€˜sweet spotâ€™ areas for optimal depositional reservoir facies lie mainly in those parts of the basin that have not benefited historically from the luxury of extensive 3D data coverage. The focus area for the Zechstein lies near the southern margin of the Mid North Sea High, in the southern portions of quads 36 and 37. This area is close enough to infrastructure to be of interest and lies away from any environmental sensitivities. Another important positive step for this part of the basin is that the historical lack of 3D data, and hence our lack PESGB November 2019 9

PES The Neglected Reefs of The Zechstein Haupt Dolomite Future Exploration Target (cont.) of detailed understanding of the seismic facies, is currently being addressed by a new seismic survey sponsored by Ardent. But this is not all that is happening. 2019 has heralded the long overdue renaissance of the Zechstein Play, with at least one well offshore well drilled targeting the Zechstein Carbonates (currently of tight hole status), along with testing at West Newton onshore UK in PEDL183. Serious interest is now being shown by several companies, both large and small. Additional 3D as well as 2D data are being acquired over key areas, as the play gears up to become a future exploration hotspot. Based only on the historical 2D data available to us, across the southern boundary of quads 36/37, we have extensively mapped a large reefal promontory (affectionately named the Elephants Foot). The principal reservoir comprises of reefal build-ups of the Z2 cycle Hauptdolomite, deposited as nonskeletal limestones in shallow water settings (well within the photic

zone), above a legacy topography composed of Carboniferous anticlines that were subsequently draped by thickened banks of Z1 Werra Anhydrite. These were subsequently covered by the overlying Z2 Strassfurt Halite and Anhydrides. The Formation is believed to have been extensively altered post deposition by dolomitization and heavy fracturing, which can (even pre-3D) be seen on the legacy 2D seismic. It is expected that very little of the original fabric remains. The source rocks for the play are believed to be lowermost Namurian and Visean shales, which source the nearby Breagh Field (500bcf), and the cluster of Zechstein gas fields in the Cleveland Basin. The Zechstein may also be self-sourcing and potentially oil prone in the area! Being armed with new state of the art 3D seismic gives us the opportunity to pursue a variety of exploration plays, seen and illuminated clearly for the first time. These range from isolated patch reefs (as seen at Crosgan), shoal features (as seen

Figure 1: Paleo-Geographical map showing the area referred to as the Elephants foot. 10 PESGB November 2019

at West Newton), reefal front buildups, talus slopes and back reef ooid banks and lagoonal areas- to name but a few. Ardent Oil have been working on this play for a number of years now, but certainly do not claim to have all the answers! By its very nature the Zechstein is complex, requiring detailed facies mapping and a clear understanding of the prospect geometries, as traps are likely to involve components of stratigraphic as well as structural seal, both lateral and vertical, along with diagenetic and / or fracture related components of either porosity destruction or enhancement. The ability to map in this detail is what has been historically lacking in the play. Explorers of 2019 and beyond should be able to carefully map Zechstein prospect geometries, using 3D data to best effect, while simultaneously hunting porosity using inversion or other techniques, depending on the available calibration data.

The Carboniferous of the Midland Valley Field trip leaders: Graham Leslie and Mike Browne, British Geological Survey

The Spireslack abandoned opencast mine offers a spectacular opportunity to examine many aspects of Carboniferous geology of the Midland Valley in Scotland. During this 1.5 day field trip, which will be led by Leslie Graham and Mike Brown from the British Geological Survey, we will be looking at the sedimentology, structural geology, palaeontology and economic geology of Carboniferous coal bearing strata that have been of great importance in the past. Given the recent activity around the southern margin of the Mid North Sea High, where age-equivalent rocks are found prospective, this field trip offers a good opportunity to study analogues in the field.

AGENDA Friday 24th April – Arrival in village of Cumnock – late afternoon or early evening. Participants are asked to organise their own travel to and from Cumnock.

Price: £500 (Includes two nights in a hotel (single-room), travel by minibus from Aberdeen and back, pick-up from Glagow Airport if required, Friday and Saturday evening meals, packed lunches on Saturday and Sunday and a field trip guide).

pesgb.org.uk

Saturday 25th April – One day visit to Spireslack abandoned opencast mine. During the evening a short lecture will be given by the field trip leaders to put the observations of the day into a more regional and scientific context. Sunday morning 26th April – Visit of a few geological sites to further put the geology of the Midland Valley in context. The field trip will draw to a close after lunch around 1 pm.

REVIEW

AFRICAN E&P CONFERENCE By Kevin Dale, PESGB Africa Chairman In early October, the PESGB / HGS Africa conference was back in London: “smarter, better,stronger” than ever. Some 600 delegates gathered at the Olympia in a buoyant and positive mood to enjoy two days (plus) of research on African geology and the latest on African activity. The conference, now in its 18th year, has established a reputation for strong and relevant technical content, attracting a diverse mix of academics, consultants, service companies and operators, and offering a unique opportunity for networking. The conference kick-started with a specialist technical workshop on the variations in heat flow, fluid flow and magmatism across the continent in both space and time and the implications for source maturation and reservoir diagenesis. The experienced panel of speakers from service companies, consultants and operators (Duncan MacGregor, Helen Doran, Tiago Cunha, Roger Baudino, Christine Yallup and Nick Cameron) ensured that this was a very well attended event, drawing the largest ever audience to an PESGB Africa pre-conference workshop. Discussions continued through the evening, as participants benefited from the icebreaker event in the Hilton Olympia Ballroom which provided an extra opportunity to network and an early glance at some of the posters. Again, this was well attended, as those that had participated in the speed networking event boosted numbers beyond the committee’s expectations. and Unfortunately ‘fluid flow’ was a problem as the beer ran dry! The heart and soul of the PESGB Africa conference is, and always will be, the technical programme. The consensus was that this year’s offering was the best ever. The number of top quality abstracts submitted made the job of Technical Chair, Helen Doran, and her committee very hard. They had to turn away some really good offerings, but the structure and content of the resulting programme of presentations was widely applauded by delegates. This year’s conference was opened by Dr Adiyaman Lopez of UNESCO, who highlighted their focus on both Africa and her team helping early career geoscientists. UNESCO programmes in Education, Science and Culture seek to help lift the third world out of poverty. Building on previous years, this year two full parallel sessions offered delegates the choice between technical deep dives in the main auditorium and regional overviews, data first looks or updates on African activities in the workshop sessions. The venue also had plenty of space to display the excellent data-rich posters, which were organised geographically for ease of access. One highlight of the program was the back to back views 12 PESGB November 2019

presented by Shell and Exxon surrounding the enigma of the origin of East Africa gas. The talks captured the ethos of the conference, companies willing to share data to generate new ideas and fuel unanswered questions on subjects that have puzzled the geoscientist for years. Once again, the depth and insight of knowledge coming out of research in academia was impressive, a group of papers looking to unravel source to sink and establish provenance across NW Africa providing the framework for any future exploration efforts in the region. Long may this fruitful link between academia and industry continue. The conference also reminded us to go back to sound regional work, a beautiful example presented on unlocking the Cretaceous turbidite play in Niger and Chad. There were some great new discoveries there for our colleges in the industry press to report on. Delegates will long benefit from the technical insight provided at the conference, via the hard-copy full colour abstract volume and the online-digital extended abstracts. Thanks to those who were very generous with the knowledge and data shared. There was a busy and worthwhile trade exhibition, with 40 companies and organisations represented this year. It was great to see more African participation than ever before, this included governmental delegations from Benin, Gabon, Madagascar, Namibia and Sierra Leone. A big thank you to the sponsors and exhibitors; their invaluable support helps underpin not only the conference, but our society itself. Thank you to the PESGB & exhibition management team who put the event together and the very valuable guidance of the organising and technical committees of eminent volunteers drawn from the membership. Finally thank you to the authors, delegates and their supporting organisations, for sharing and collaborating at this event to help drive forward research, knowledge and profitability. The conference closed, as always, with the awards for the best presentations, this year under the watchful eye of the new Chair of Judges, Richard Blight of Shell. To present the prizes we were delighted to welcome Professor Iain Stewart, known to many for his BBC TV documentaries, such as ‘Planet Oil’. Clare Glover (ExxonMobil), Felicia Winter (TGS), Michael Bourne (CNOOC International), Sigrún Stanton (Halliburton) and Max Casson (University of Manchester) took the honours. All this was offered by the PESGB (a not for profit organisation) at a deliberately low-cost. The objective is to maximise the benefit to all members, to our science and to our business.

#PETEX2020 @PESGB

PETEX is the largest subsurface-focussed global E&P conference and exhibition in the UK. Complementing the 3-day technical conference, over 6000m2 of exhibition space will feature industry operators, service companies, national oil companies, financial companies and professional organisations. With a technical programme primed to discuss the latest global activity in exploration, field development, reservoir management and unconventional exploitation, and numerous opportunities for networking, PETEXâ€™s audience reflects its high quality, technical conference content. Olympia London is currently undergoing a ÂŁ1bn redevelopment; with a project of this scale and size it has taken them slightly longer than anticipated to finalise all of the moving parts, so as a result they are unable to accommodate PETEX 2020. We look forward to seeing their new facilities, but in the meantime PETEX will be returning to the Business Design Centre in Islington, a favourite amongst many of our delegates and exhibitors for its accessibility and vibrant social scene. Careful and creative planning means that we have been able to deliver a floorplan with a larger square footage than PETEX 2018 at Olympia London.

Machine Learning Machine Learning applied to seismic data to support geological interpretation and reservoir modelling With Tim Gibbons, Hoolock Consulting Thursday 7 November 2019, 6pm PESGB Offices, Victoria We interpret seismic data in order to develop our geological understanding of a region, support play fairway analysis and build reservoir models. The application of machine learning to seismic interpretation has the capacity to improve both the quality of our interpretation and the speed with which we interpret the data. However, it is important that we apply the right machine learning at the right time and for the right reasons otherwise we run the risk of losing the advantages that it gives us. This presentation will demonstrate the way that both unsupervised and supervised machine learning can improve seismic interpretation and look at how varying the parameters affects our results. Unsupervised machine learning requires no significant input from the user beyond the basic parameters. The computer uses machine learning algorithms to cluster data points into groups with similar properties. This can lead to a greater understanding of the geology that we are seeing in the seismic. Supervised machine learning requires the input of training data. In this instance, the computer learns what a particular image contains and then looks for similar images. This is used for facies and fault interpretation. In both instances, the quantity and quality of the input data will affect our result. In addition, there are basic parameters that affect the algorithms and have the capacity to modify the result. Understanding how these parameters affect the result will have a significant bearing on the results that we get and will hence impact the ability of the process to affect the outcome of the reservoir model. It is therefore important that the geoscientist understands more than an equation.

Old Timers PESGB Offices, Victoria The Old Timers have had three positive initial meetings. We have enjoyed robust conversations about a wide variety of geology and petroleum geology subjects, from the UK and around the world, some current some historical. You are invited to come and join the conversation. Do come prepared with what you would like to discuss. After an hour or so of debate we shall adjourn to a local eatery for lunch.

Brent: from Barrel to benchmark Review by Niamh McGovern (IHS Markit & PESGB YP Committee)

The PESGB YPs would like to thank CNOOC and Ireland’s Petroleum Affairs Division (PAD) for their generous sponsorship of our special interest group.

We would also like to thank IHS Markit (London) and Spirit Energy (Aberdeen) for providing high quality facilities where we are able to host our evening seminars.

pesgbyp@gmail.com

38 PESGB November 2019

From Brent to Benchmark was a fascinating seminar across the Upstream and Downstream Sectors. The evening started with Kirstie Wright from North Sea Core who ran two Core workshops illustrating what is core and its effectiveness within the exploration industry. Our second North Sea Core speaker, John Marshall, discussed the exploration methods used to develop an extensive geological story of the North Sea and how this contributed to the discovery of the Brent oil field. John further explained the success of the discovery and how it led to a proliferation of further discoveries within the North Sea. This was a very extensive talk that outlined the exploration and production methods very clearly for the benefit of attendees from non-geological backgrounds. Finally, our Argus Media representative Michael Carolyn, illustrated a different perspective on how the Brent field establishes a benchmark for the downstream oil and gas industry and influences the oil price and financial market globally. We sincerely thank Kirstie Wright and John Marshall from North Sea Core for giving insightful and excellent technical seminars, Michael Carolyn from Argus Media for providing an in depth non-technical seminar, Argus Media (London) for hosting the event and CNOOC International for their continued support of the PESGB YP’s.

Thad’s presentation was themed around under explored Tertiary injectite plays, and the new insights arising from the forefront of work being done at Azinor Catalyst, specifically within the Beryl Embayment, UK North Sea. From start to finish Thad’s lecture was filled with fascinating information and vivid graphics. Notably, the audience was talked through a wonderful video, outlining the theorised formation of injectites, by definition, in the area of interest. After delving into the hypothesised thoughts on injectite formation, Thad went on to explain why these sedimentary structures attribute such good porosity and permeability vales, making them integral in exploration efforts across the UK North Sea. The talk presented the interesting history of injectites (formed due to overpressuring within the subsurface) and how they were historically avoided by reservoir engineers due to the increased risks over-pressured formations present when drilling. However, in recent years how and why these once evaded formations are rapidly becoming the target for exploration efforts across the globe. Despite a pesky Windows 10 update throwing an intermission at Thad’s talk, he carried himself extraordinarily well and kept the audience both engaged and entertained whilst the issues were fixed. This momentary break allowed for mid-presentation questions which proved an unusual and welcome change to the standard format of the evening lectures. After the talk had concluded, the PESGB community were able to relax at Burlington House and discuss the captivating elements of Thad’s talk over Azinor Catalyst’s signature dark and stormy cocktail.

Ireland’s Offshore Basins: Can Past Disappointments Lead to Future Success? Offshore Ireland has nearly 50 years of exploration history. The last licensing round held in 2015 saw a significant increase in the interest of the exploration potential in the Irish offshore. Licences were picked up by majors including ExxonMobil, ENI, CNOOC, Equinor and Woodside and smaller independents including Europa, AzEire and Predator. To date, a total of 26 discoveries have been made from the drilling of 189 E&A wells offshore Ireland. Drilling commenced in the 1970’s and a total of 65 E&A wells were drilled during the decade. The first discovery, Kinsale Head, was made in 1971. Drilling activity decreased slightly in the 1980`s with 59 wells drilled. The 1990’s and 2000’s saw the drilling of 30 wells and 28 wells respectively and since 2010 a total of 7 wells have been drilled offshore. Most of the drilling activity to date has focused on the Celtic Sea area. More recently companies have started exploring further offshore in the deep waters of the Porcupine Basin. However, success has been limited so what does the future hold for Ireland`s offshore?

Figure 1Offshore Ireland Fields and Prospects Map

REGIONAL GEOLOGY The five main offshore basins of Ireland comprise the Celtic Sea Graben System, Central Irish Sea, Rockall, Porcupine and Northwest Ireland Offshore. These extensive Mesozoic basins are subdivided into several smaller rift basins: SlyneErris, Goban Spur, Kish Bank and the North and South Celtic Sea basins. This article will discuss the Porcupine, Northwest Offshore Basin and Celtic Sea Graben System. These basins evolved in response to three phases 44 PESGB November 2019

of basin development occurring in the Permian-Triassic, Mid-Late Jurassic and Cretaceous to Cenozoic ages. FIELD HISTORY OF THE PORCUPINE BASIN Several plays have been identified within the Porcupine Basin, ranging from Jurassic through to Cretaceous and Cenozoic in age, with a focus on both structural and stratigraphic plays. Three discoveries - Burren (1978), Connemara (1979) and Spanish Point (1981)

have been made in the northern part of the Porcupine Basin. The Burren exploration well targeted an Upper Cretaceous reef and Upper Jurassic sandstone play and was drilled by Phillips Petroleum. Connemara and Spanish Point have reservoirs of the Steerdagh submarine fan sandstones and fluvial sandstones of the Minard Formation. The hydrocarbons are trapped in tilted fault blocks and capped by Lower Cretaceous shales. Over the years, the ownership of these discoveries has changed,

N E W S F E AT U R E

however, to date all three discoveries are yet to be developed. IMPACT OF 2015 ATLANTIC MARGIN LICENSING ROUND IN THE PORCUPINE BASIN Recent exploration in Ireland has focused on the Porcupine Basin. Even before the 2015 Atlantic Margin licensing round big companies were entering the Irish offshore with the likes of Woodside, Cairn and Kosmos picking up acreage in the basin. But, it was during the 2015 Licensing Round that interest increased. A total of 28 Licensing Options were awarded across the Porcupine Basin (and further north) to majors ENI, BP, ExxonMobil, Equinor, Woodside and CNOOC and smaller independents including Europa, AzEire and Providence. This was the largest number of awards in any Irish round to date (PAD 2016). The surge in interest was driven by a combination of new seismic data, technological improvements and new thinking. Early exploration activity was focused on large Jurassic and Triassic fault blocks. However, improvements in seismic technology and improved coverage have allowed shallower and far more subtle features to be identified. Therefore, potential exists in both large traditional structural targets and also stratigraphic plays. Discoveries in other parts of the Atlantic Margin in West Africa and Canada have also shown the potential that exists in different plays in the Irish offshore. The success of the round is an indication of the potential of the frontier Irish Atlantic Margin, particularly the prospective Porcupine Basin. Seismic acquisition has already commenced but drilling is not required to take place on the new acreage before 2021. To date 6 seismic surveys have been shot across 2016, 2017 and 2018 within the Porcupine Basin. In the Southern Porcupine Basin (SPB), three high impact wells have

been drilled over the last 6 years: Dunquin North in 2013 (ExxonMobil), Druid/Drombeg in 2017 (Providence Resources) and Iolar in 2019 (CNOOC). All three wells failed to encounter hydrocarbons. The Dunquin North well targeted a Lower Cretaceous isolated carbonate build up. The well was spudded in April 2013 and encountered a porous carbonate reservoir ~245m thick but it was water bearing. Providence thought the presence of gas chimneys associated with the targeted structure is evidence of trap failure. The Druid/Drombeg 2017 well targeted two separate stratigraphic objectives within a single vertical well. The Druid prospect comprised two Paleocene deep-water sandstone fans located at ~4,000m. The fans were thought to be 85m thick with porosities of 30%. Drombeg was interpreted as a Lower Cretaceous sandstone deep-water fan, located at 5,000m thought to be 45m thick with 20% porosity. Both targets were dry. Seismic analysis and spectral decomposition identified an erosive channel cutting the Druid fans suggesting the channel was backfilled with mudstone, thus providing an effective trap and seal. However, Providence thought that the failure of this backfilling mudstone led to the reservoir being water wet. Further upside at the well location exists in the Diablo target however this wasnâ€™t tagged by the exploration well. The third and most recent well drilled in the SPB was CNOOCâ€™s Iolar well in May 2019. Iolar was interpreted as a pre-syn rift Jurassic structural closure on the western flank of the basin. The main objective was the Middle Jurassic (Kenmare Formation) with secondary targets in the Upper Jurassic (Bantry Group) and Cretaceous submarine channel complex (Greensand Formation). These targets were predicted to be sourced and sealed by the Kimmeridge Clay Formation. However, in August 2019

it was confirmed that the well was a dry hole. Even though recent drilling activity has yielded disappointing results, potential remains in this significantly underexplored basin, with several high impact wells scheduled in the coming years. Woodside is potentially looking to drill the Beaufort prospect in FEL 5/13. Beaufort is a stratigraphic trap with an Upper Jurassic reservoir charged by the Kimmeridgian-Tithonian aged source rocks. The overpressured Upper Jurassic and Lower Cretaceous shales provide ideal conditions for the stratigraphic trapping and sealing of the reservoirs. Upside in the acreage consists of the underlying Walton prospect. Woodside may look to drill a well in 2020 and has been actively farming out the prospect. Following the unsuccessful Dunquin North well, attention has turned toward the southern structure. ENI plans to drill an exploration well on Dunquin South in FEL 3/04 in 2020. Dunquin South has a similar Cretaceous carbonate reservoir to that of Dunquin North, but the fluid escape features seen above Dunquin North are absent at this location. Dunquin South has a resource estimate of 1.4 Bboe. Further prospects identified within the basin include Avalon. This is an analogue prospect to Druid and adjacent to Dunquin North, it is interpreted to be a Paleocene north-south orientated basin floor channel sand system. Providence predicted that the system is sourced from the north with shales becoming localised towards the south. Kiely, Kiely West and Kiely East are three large tilted fault block structures with Middle Jurassic marine sandstone reservoirs, located within the FEL 2/13 licence. These prospects are sourced and sealed by the Kimmeridge Clay formation. The 43/13-1 well located within FEL 2/13 PESGB November 2019 45

storage facility. Further development in 2006 enabled the storage facility to receive gas from the onshore network.

FIELD HISTORY OF THE CELTIC SEA The North Celtic Sea Basin hosts three producing fields (Kinsale Head, Seven Heads and Ballycotton) and several discoveries. Kinsale Head was discovered in 1971. Marathon Oil drilled and successfully tested the seismically defined shallow anticlinal Lower Cretaceous feature. This was a surprising discovery as the first well was drilled slightly off structure but encountered oil and gas shows within the Greensand and Wealden reservoirs. The field came onstream in 1978 and has been a key domestic gas producer for Ireland. Operator, Kinsale Energy confirmed that production will cease in 2020/21. It is expected that well abandonment and decommissioning operations will commence in 2021. The operator has estimated that Kinsale Head has produced in the region of just under 2 Tcf of gas, making it the largest Cretaceous gas discovery offshore Ireland to date. The Seven Heads gas field was discovered in 1974 by Marathon’s wildcat 48/24-1, which encountered gas within the Lower Cretaceous and Wealden reservoirs. At the time of discovery, it was not considered to be commercial and therefore did not come onstream until 2003. The field was tied-back to the Kinsale Head facilities. Ballycotton, a field also analogous to Kinsale Head was discovered by Marathon in 1989 and has a Lower Cretaceous reservoir with a shallow anticline. It was brought onstream in 1991 and continues to produce. In 1995 Kinsale Head Southwest was discovered and subsequently tied into the Kinsale Head development, coming onstream in 1999. In 2001 the field was redeveloped as a gas

LOOKING FORWARD IN THE CELTIC SEA Beneath the Kinsale Head Southwest field in the Lower Cretaceous stacked Lower Wealden and Purbeckian sandstones lies the Barryroe oil field. Barryroe has remained undeveloped since its discovery in 1973. However, current operator Providence Resources has been attempting to mature the development. In 2018 it signed a farm-out agreement with APEC Energy Enterprise to develop the field. In September 2019 a site survey for development drilling was undertaken. Another discovery, Ram Head, was made in 1984 by Marathon with well 49/19-1. The discovery is now operated by Predator and the company has announced a potential appraisal programme on the discovery. The company is looking to re-enter 49/19-1 to test the discovered gas to understand the scope of a potential development. Predator state that a reservoir engineering study shows development potential of 10 wells with a recovery of 1 Tcf of gas over an 11-year period.

46 PESGB November 2019

FIELD HISTORY OF THE NORTHWEST OFFSHORE IRELAND BASIN The Northwest Offshore Ireland Basin is subdivided into the Slyne and Erris sub-basins. The Slyne subbasin hosts the Corrib gas field. First discovered in 1996 by Enterprise Energy it is the largest gas discovery since Kinsale Head. The successful discovery proved the highly porous and permeable nature of the Triassic Sherwood sandstone reservoir. The Carboniferous coals charged the Triassic reservoir and the halite Merica Mudstone group sealed the Corrib anticline, creating a four-way dip closure.

Shell acquired Enterprise in 2001. The Dutch major encountered issues developing Corrib but finally bought the field onstream in December 2015. At peak production Corrib has produced approximately 96% of Ireland’s gas demand. Subsequently Shell exited Corrib in 2016 and Vermillion became operator. Corrib’s success led to further exploration interest within the Slyne subbasin (Figure 2), and several prospects have been identified. The Corrib South prospect owned by Predator is located 20km south of Corrib and has the same Triassic Sherwood sandstone reservoir. Corrib South is estimated to hold resources of 424 Bcf and could be tied into the Corrib infrastructure. Key risks include the seal effectiveness and hydrocarbon migration. A potential well is planned for 2020. Europa has a number of prospects in the area. In FEL 4/19 lies the Inishkea prospect. Inishkea is a large faultbounded, pre-rift Triassic prospect mapped on 3D data. Its located 11km northwest of Corrib and also has a Triassic Sherwood sandstone reservoir. The prospect has best case resource estimates of 968 Bcf and is understood to be sourced from the Carboniferous and sealed by a combination of the Triassic Uilleann halite and also fault seal. The key risk with Inishkea is seal effectiveness due to Mid-Cretaceous inversion causing shortening and salt movement throughout the area, leading to the removal of approximately 1km of overburden. The absence of a gas chimney associated with Inishkea compared to Corrib is likely to derisk this prospect. Europa has been attempting to farm out the prospect with a view to drill a well in 2020. Inishkea West and Northwest provide exploration upside in the licence. GIIP for all prospects in FEL 4/19 is estimated to be 2,363 Bcf. Further exploration upside exists within Europa’s acreage in the form of Corrib North,

another Triassic Sherwood sandstone structure. OUTLOOK Further exploration activity is required to unlock the hydrocarbon potential of offshore Ireland. With many of the Licensing Options being converted in to Frontier Exploration Licences from the 2015 licence round, it is hoped that further exploration activity is on the horizon. More exploration is required to prevent Ireland’s energy security from becoming increasingly strained as producing fields such as Kinsale Head approach abandonment. As Corrib begins to decline Ireland will need to either replace this domestic gas supply or become increasingly reliant on imports. This coupled with the Climate Energy Emergency Bill which was put forward through Dáil Eireann has put the future of the oil and gas industry under scrutiny. The Taoiseach Leo Varadkar,

recently put forward his proposal at the UN Climate Action Summit to phase out oil exploration in Irish waters, in order to achieve carbon neutrality by 2050. The Government confirmed that companies can continue to explore for natural gas as it sees gas playing a role in Ireland’s Energy security for years to come. The Irish Offshore Operator Association has announced: “that existing exploration licenses will be unaffected and the Government announcement only relates to future licenses not those granted in the 2015 Licence Round”. Thus it is clear that the Government’s proposals “will relate to future applications” and that “existing licences will remain valid”. IOOA, Chief Executive Officer, Mandy Johnston said: “It is important that further clarity is given on how the Government’s proposal for future licencing rounds will be implemented as a representative body investing considerably in

offshore Ireland we are seeking a meeting with Minister Canney at the earliest possible opportunity”. With drilling activity planned for 2020 and companies working up their 2015 licence round acreage, there is the potential for future discoveries to address Ireland’s falling gas production. Despite the optimism, the Irish operating environment comes with its challenges, such as a lack of transport infrastructure and high deep-water drilling costs. Although more than half of the Licensing Options awarded during the 2015 round have been progressed to Frontier Exploration Licences it will be drilling results that ultimately determine its success. Ireland now needs proven commercial discoveries. For further information contact: Adrien Charaudeau, IHS Markit Adrien.Charaudeau@ihsmarkit.com

PES International News ANGOLA The first of four roadshows for the 2019 Licensing Round was held in Luanda on 3 September, with an audience of over 300 attendees. A technical presentation was made in the morning to provide an overview of the geology and potential of the blocks on offer and details on the fiscal terms, timeline and requirements. The afternoon was dedicated to private discussions with potential investors. Similar events took place in Houston on 10 September, London on 17 September and Dubai on 23 September. Ten deepwater blocks are being offered, nine of which in the Namibe Basin and one in the Benguela Sub-basin (Kwanza Basin). The tender will close on 12 November 2019, with the Agência Nacional de Petróleo, Gás e Biocombustíveis (ANPG) expecting to sign contracts by end-April 2020. Angola is the second largest oil producer in SubSaharan Africa with an average output of 1.4 MMb/d. AUSTRALIA While its gas exploration programme has been temporarily suspended, Cooper Energy has further expanded its portfolio offshore Victoria. The company has been awarded exploration permits VIC/P75 and VIC/P76 after successful bidding in the 2018 Offshore Federal Acreage Offer. VIC/ P75 covers an area of 808 sq km in the Gippsland Basin and encompasses two gas discoveries, Veilfin 1 (1984) and Zanegrey 1 (2005). It is also surrounded by several fields, notably the Marlin-Turrum, Snapper and Barracouta gas fields to the north and the Kingfish and Fortescue oil fields to the south and east, respectively. VIC/P76 is a 162 sq km block in the Otway Basin, located directly east of VIC/P44, which hosts the recent Annie 1 gas discovery. The permit is undrilled, but good quality 3D seismic 48 PESGB November 2019

data covers most of it and several accumulations are located nearby. VIC/ P76 is estimated to hold the eastern extension of the Annie discovery as well as the Nestor prospect in the south. Cooper currently holds a 100% interest in both licences. BRAZIL The First ANP Open Door Bid Round has resulted in the provisional award of 45 blocks out of the 287 areas on offer. In total, 33 exploration blocks and 12 mature fields in five basins received winning bids from 12 groups. The blocks cover nearly 17,000 sq km and attracted work commitments valued at around USD 80 million. A consortium of ExxonMobil, Murphy Oil and local company Enauta secured the only offshore acreage, namely three blocks in the ultra-deepwater Sergipe-Alagoas Basin, adjacent to their existing position. Onshore, Texas-based PetroVictory and Uniper subsidiary Eneva emerged as the leading bidders, respectively winning 16 blocks in the Potiguar Basin and 6 blocks in the Parnaiba Basin. EAST TIMOR Under the new maritime boundary between East Timor and Australia, existing acreage holders in the former Joint Petroleum Development Area (JPDA) have secured new contracts. Eni and ConocoPhillips have replaced their JDPA contracts with new Production Sharing Contracts (PSCs) under the administration of the East Timor government. Eni has been awarded TL-SO-T 19-11 and TL-SO-T 19-10 in the Bonaparte Basin, covering a combined 785 sq km and containing the Jahal, Krill and Kuda Tasi oil discoveries, along with the Kitan oil field, which ceased production in 2015. In TL-SO-T 19-11, Eni operates with 40.53%, partnered with Inpex (35.47%) and Timor GAP

(24%), while in TL-SO-T 19-10, the Italian company holds a 40% operated stake, partnered with Inpex (35%) and Repsol (25%). ConocoPhillips has secured the TL-SO-T 19-12 and TL-SO-T 19-13 PSCs. The TL-SO-T 19-12 notably covers the western half of the Bayu-Undan field, which supplies gas to the Darwin LNG facility, also operated by ConocoPhillips. The US company operates with 61.66%, partnered with Santos (19.27%) and Inpex (19.07%). In TL-SO-T 19-13 participants are ConocoPhillips, operator with 50.63%, Eni (26.87%) and Tokyo Timor Sea Resources (22.5%). EGYPT Eni has started production at the Baltim Southwest gas field in the Baltim South concession in shallow waters of the Niger Delta Basin. The field was discovered in June 2016 and sanctioned in January 2018 under the company’s fast track approach to selected development projects. Initial production was achieved from well BSW1 at a rate of 100 MMcf/d. Eni plans to drill another five wells, with the target of reaching 500 MMcf/d output by mid-2020, utilising a new platform connected via a 44 km pipeline to the onshore Abu Madi gas plant. The field is situated 12 km off the Mediterranean coast, within the Greater Nooros area, estimated by Eni to hold a total of some 3 Tcf of gas in-place. The Baltim South development block is held by Eni (operator and 50% interest holder through its subsidiary IEOC) and BP (also with 50%), although Petrobel, a joint venture between IEOC and the state company EGPC, carried out the development work. GUYANA Both Tullow Oil and ExxonMobil announced new discoveries in September, further bolstering the hydrocarbon potential of the Guyana

N E W S F E AT U R E

Basin. Building on the recent JethroLobe discovery, Anglo-Irish operator Tullow Oil has successfully encountered oil in Joe 1, its second exploration well in the Orinduik block. The well was drilled with the “Stena Forth” drillship in 780 m of water to a total depth of 2,175 m, intersecting 14 m of net oil pay in high-quality reservoirs and opening a play in the Upper Tertiary. With initially-estimated P50 gross unrisked prospective resources of 148.3 MMboe, Tullow stated that the well de-risks several Tertiary and Cretaceous prospects in the western part of the licence. In the neighbouring Stabroek block, ExxonMobil has made a new discovery with the Tripletail 1 wildcat. The well was drilled with the “Noble Tom Madden” drillship in 2,000 m of water around 4 km northeast of the Longtail discovery, encountering 33 m of high-quality oil-bearing sandstone. Total recoverable resources for the permit are now estimated to exceed 6 Bboe. NAMIBIA Total and Qatar Petroleum have signed an agreement to build upon their existing partnership. The latter will acquire stakes in two adjacent deepwater blocks in the Orange Sub-basin – namely a 30% interest in PEL 56 (Block 2913B) and a 28.33% stake in PEL 91 (Block 2912) – for an undisclosed consideration. Block 2913B covers 8,252 sq km in water depths of 2,500 – 3,400 m. An exploration well is planned on the block in 2020, likely targeting the Venus prospect. Remaining interest will be Total, operator with 40%, Impact Oil and Gas (20%) and NAMCOR (10%). Block 2912 covers 7,900 sq km in water depths of 3,000 – 4,000 m. Total will retain a 37.78% interest, with Impact and NAMCOR holding 18.89% and 15%, respectively. Total and Qatar Petroleum have been partners in the African continent since

2008, when the latter acquired a 20% stake in the Taoudeni Onshore licence in Mauritania. In 2013, Qatar Petroleum bought a 15% share in Total E&P Congo and more recently, the two companies teamed up in South Africa, drilling the high-impact Brulpadda discovery well in offshore Block 11B/12B, and in Kenya. NIGER A project for large-scale oil exports from Niger has taken a major step forward with the signature in midSeptember of a convention for the transport of crude oil through the proposed Niger-Benin pipeline. The sanction by China National Petroleum Corporation (CNPC) and the Niger authorities has allowed construction works to start at Koulélé in the Agadem area. The USD 4.5 billion project will consist of a 2,000 km pipeline, of which 1,300 km in Niger and 700 km in Benin. The link between the two countries, which will enable the transport of the crude oil produced in the Agadem area to Port Sémé in Benin, is expected to be completed by end-2021. Oil production from Niger, currently limited to 20,000 b/d, is expected to substantially increase and exceed 100,000 b/d in the coming years. Other export solutions were considered in the past, including a Niger-Chad-Cameroon line, which was finally abandoned. NIGERIA Eni has announced a significant discovery in OML 61, onshore Niger Delta. The Obiafu SW Deep 4 exploratory well (also known as Obiafu 41 Deep) was drilled to test the deeper sequences of the producing Obiafu-Obrikom field and reached a total depth of 4,374 m, encountering gas and condensate in a deltaic sequence of Oligocene age comprising more than 130 m of high quality sands. The company estimates

the find to hold approximately 1 Tcf of gas and 60 MMbbl of associated condensate, with further upside to be assessed with upcoming drilling as part of a campaign targeting nearfield and deeper-pool opportunities. Eni plans to place the well on production immediately, at a projected rate in excess of 100 MMcf/d of gas and 3,000 b/d of condensate, bolstering resources at the Obiafu-Obrikom field, which was discovered in 1967 and brought onstream in 1973. The field has produced roughly 75% of its existing resources. Eni operates OML 61 with a 20% interest via subsidiary Nigeria Agip Oil Company, partnered with NNPC (60%) and Oando (20%). RUSSIA Rosneft has commenced development drilling at the next field in the Erginskiy cluster in Khanty-MansiyskYugra Autonomous Okrug in Western Siberia. The Chaprovskoye field development will include a total of 12 wells, of which eight deviated and four horizontal, to be drilled by the end of 2019. Chaprovskoye was discovered in 1997 in the Ural-Frolov Province and contains 3P reserves estimated at 251 MMbbl of oil. The Erginskiy cluster, which comprises a part of the Priobskoye field, plus the Erginskoye Zapadnoye, Kondinskoye, Chaprovskoye, Yendyrskoye and Irtyshskoye fields, is a key project for Rosneft. The state-controlled company achieved first oil from the cluster in 2017 and followed up with the West Erginskoye field earlier in 2019. Combined reserves are estimated at 299 MMt of light oil (2.17 Bbbl) and several techniques are being applied to optimise the recovery, including horizontal drilling and multistage hydraulic fracturing. SENEGAL The first appraisal well on the 2017 Yakaar 1 discovery has enabled PESGB November 2019 49

PES operator BP and its partners in the Cayar Offshore Profond permit to confirm the presence of gas in highquality Cenomanian sandstones. Yakaar 2 has encountered some 30 m of net gas pay nine kilometres from the discovery well, proving the southern extension of the accumulation. The results provide confidence to the partnership that Yakaar, in conjunction with the nearby Teranga discovery, can support a standalone LNG project and supply significant volumes of gas to both domestic and export markets. Yakaar 2 marks a new milestone for BP and Kosmos after the successful GTA-1 well in the Greater Tortue area earlier in 2019. The “Valaris DS-12” rig will next move to Block C-8 offshore southern Mauritania to test the Orca prospect, with a gas-in-place potential of 13 Tcf. BP operates Cayar Offshore

Profond with a 60% interest, with partners Kosmos and Petrosen holding 30% and 10%, respectively. SRI LANKA The Government of Sri Lanka announced on 27 August 2019 that it has entered into an agreement with Total, allowing the company take on Equinor as partner in its ongoing studies of the hydrocarbon potential of blocks JS-5 and JS-6 in the central Cauvery Basin. This follows rumours in late 2018 that discussions were ongoing with the Norwegian major for a potential farm-in. The “BGP Pioneer” seismic vessel acquired some 5,000 km of 2D seismic over the blocks in September-October 2018, with 3D acquisition likely to follow in the future. The JS-5 and JS-6 blocks jointly cover 50,260 sq km off Sri Lanka’s northeastern

coast. Total originally signed a joint study agreement (JSA) with the country’s Minister of Petroleum Resource Development in 2016 and will have the first option to negotiate terms for a production sharing contract in the case of discovery. Sri Lanka has no hydrocarbon production and Total’s two blocks are the only current valid contracts in the country, after Cairn relinquished its gas block in the offshore Mannar Basin in April 2015.

Asia-Pacific News AUSTRALIA Santos has been awarded more acreage on trend with the Dorado field which is operated by Santos (80%). The new permit, WA-541-P is in the Northern Carnarvon Basin, west of the Dorado, Roc and Phoenix South discoveries in the Bedout sub-basin. Santos will act as operator (50%)in the new acreage with partner BP (50%).The new permit is 6,964 km2 and the southern portion is directly adjacent to the structural-stratigraphic play trend, which is interpreted to extend into the new block according to Santos. The permit is close to three other Carnarvon Basin permits BP holds and, is also close to the Ironbark prospect in permit WA-359-P BP plans to drill next year with Beach Energy, NZOG and Cue. The award is for six years with a work programme of seismic acquisition, reprocessing and 50 PESGB November 2019

geotechnical studies. Strike Energy (50%) has finished drilling the 5,100m (16,732 ft) conventional gas well West Erregulla-2. It is partnered with Warrego Energy (50%) in the North Perth Basin and plans to flow test at least one of the three target horizons. Managing Director Stuart Nicholls stated at a recent conference that there is 78m (256 ft) of net pay across the three structures. The West Erregulla-2 well has reputably made three individual conventional gas discoveries and has found the deepest hydrocarbons ever discovered in Australia. NOPSEMA’s (National Offshore Petroleum Safety and Environmental Management Authority) decision on whether or not to approve Equinor’s controversial plans to drill a wildcat exploration well in the Great Australian Bight (large oceanic open bay, off the southern coastline of mainland Australia)

has been delayed for a third time. NOPSEMA announced it required more time to assess the proposal from Equinor and had scheduled a decision date for 14th November. Equinor proposes to drill Stromlo-1, in Exploration Permit EPP39 in the Ceduna Sub-basin offshore South Australia. The well would be drilled in waters 2,240m (7,349 ft) deep, take around 60 days to complete and, if approved, will spud late 2020. Jadestone Energy based in Singapore has installed new subsea umbilical cables across the Montara oilfield, offshore Western Australia in the Timor Sea. The London AIMlisted company was formally awarded operatorship of the Montara field in July 2019 but has effectively operated the field since acquiring it from Thailand’s national petroleum exploration and production company, PTTEP last year. Overall production from Montara and the nearby Stag

N E W S F E AT U R E

fields reached 13,315 barrels of oil per day in the second quarter, despite a shutdown due to cyclone Veronica in April. INDONESIA Empyrean Energy has mobilised a rig to start its Duyung PSC drilling campaign in the West Natuna basin, offshore Indonesia. Empyrean holds an 8.5% interest in Duyung alongside its partner Coro Energy, and operator Conrad Petroleum. Two wells are planned; an appraisal well designed to test the Pliocene intra-Muda sandstone reservoir at the Mako gas field discovery in the southern area of the Mako field and an exploration well designed to test the Tambak prospect beneath the central area of the field after appraisals. The Mako field is an extremely large shallow structural closure across 350 km2 (86,487 acres), located 16 km from the West Natuna Transportation System (WNTS) which delivers gas from Indonesia to Singapore.

TIMOR Timor Resources is planning to drill Timor-Leste’s first onshore well in almost 50 years in January 2020. The country has not had an onshore drilling campaign since 1972, when the Portuguese controlled the country. In 2017, the privately-listed Timor Resources won the rights to explore and develop 2,000 km2 (49,4211 acres) of onshore acreage on Timor Leste’s south coast and holds two production sharing contracts via joint venture with state-owned Timor Gap. Karau is the first well and is planned to reach a depth of 1,080m (3,543 ft). It will target the late Tertiary greywackes of the Viqueque formation, with the company estimating approximately 430m (1,411 ft) of gross reservoir interval, which is known to be oil bearing in the near surface from evidence of oil seeps. The deepest well in the five well campaign is 2,740m (8,989 ft) and is set to target a Mesozoic formation. SapuraOMV is a joint venture

between Malaysia’s Sapura and Austria’s OMV, which plans a small seismic survey across its permit AC/ P61, and adjacent areas in the Timor Sea, totalling 410 km2 (154 sq.miles). The two companies formed a strategic partnership last year with OMV taking a 50% stake worth a reported US$1.6 billion in Sapura’s upstream subsidiary. In September 2018, the new company took 70% equity and operatorship of three permits from Australian Finder Exploration, including AC/P61. The AC/61-P permit is in the Vulcan Sub-basin 250km (155 miles) from shore and 650km (404 miles) from Darwin.

PES DRILLING ACTIVITY UNITED KINGDOM As of 9 October 2019, nine exploration wells and six appraisal wells have completed in the UK this year. At the time of writing, there were four exploration wells and five appraisal wells active. In the West of Shetland, CNOOC spudded its 206/21-1 Howick exploration well on 31 August with the Island Innovator semi-submersible. The well is targeting Lower Cretaceous sandstones within a four-way dip closure in the West Shetland Basin. Hurricane Energy has completed operations with its 205/26b-14 Lincoln Crestal appraisal well which spudded on 12 July. The well was appraising 1C-2C-3C resources of 150 - 604 - 1,537 mmboe, based on an RPS Energy CPR published December 2017. Lincoln Crestal was the second in a three-well drilling campaign with the Transocean Leader in the Greater Warwick Area. The well reached total depth at 1,780m (5,840ft) TVDSS, having drilled a 720m (2,362ft) horizontal section into the fractured basement reservoir. The well flowed at a maximum stable rate of 9,800 bopd of 43° API oil with the use of an Electrical Submersible Pump and 4,682 bopd under natural flow and was suspended on 19 September. The Transocean Leader then moved to drill the third and final well in the campaign at Warwick West (formerly called Warwick Crestal). The 204/30b-4 appraisal well was spudded on 24 September and is targeting the basement reservoir at a shallower interval than the 205/26b13 Warwick Deep well which did not flow at commercial rates. Drilling is continuing at Total’s 206/4a-5 and -5Z Glendronach appraisal well, which spudded on 16 July. The well is seeking to appraise volumes reported by the operator 52 PESGB November 2019

North Sea News to be in the region of 1 tcf (166.6 mmboe) in the Lower Cretaceous Royal Sovereign Formation. A mechanical sidetrack was kicked off on 28 August as the 206/4a-5Z well. CNOOC is continuing to drill the 208/17a-4 Cragganmore appraisal well, which spudded on 19 July with the Ocean GreatWhite semisubmersible. The original discovery was made in 2012, encountering low saturation gas in Paleocene Vaila Formation sandstones within a structure estimated to be c. 50 km2. In the Northern North Sea Cairn spudded its 3/17a-3 Chimera exploration well on 27 September with the Stena Don, which mobilised from development drilling operations for Total in the West of Shetland. The well is targeting Pmean resources of c. 150 mmbbl in the Paleocene Lista Formation, Heimdal Member, with a secondary objective in the shallower Eocene. Chimera is the largest oil prospect to be tested this year, based on published pre-drill resources. In the Central North Sea i3 Energy completed operations at its 13/23c9 Liberator appraisal well with the Borgland Dolphin semi-submersible on 18 September. The well failed to find hydrocarbons in the Lower Cretaceous and has been abandoned as a dry hole, with the target reservoir encountered beneath the OWC of the discovery well and the upper Captain sand having pinched out at this location. The rig then moved to drill an appraisal well on the Serenity structure, which is considered to be an extension of the Lower Cretaceous Tain discovery. This well was moved from the third to second slot in the drilling programme whilst results from the initial Liberator well are assessed prior to drilling an appraisal well to the west of the 13/23c-9 well. Equinor spudded exploration well 22/10b-9 on 23 September with the West Phoenix semi-submersible

which mobilised from operations in the Norwegian sector. Mechanical issues necessitated a re-spud on 25 September as well 22/10b-9A. The well is targeting the Upper Jurassic Fulmar Formation in the Lifjellet prospect, as a cross median line structure on the Jæren High. The acreage was awarded to Equinor and Shell in the 29th Round, with a firm drilling commitment which will be satisfied by this exploration well. In the Southern North Sea, Premier Oil is continuing to drill its 42/28d-14 Tolmount East appraisal well which was spudded on 8 August with the Valaris (previously Ensco) 123 jackup rig. The well is targeting 300 bcf in the Permian Rotliegend as an extension of the Tolmount Main field, which would be incorporated into the c. 500 bcf Tolmount development. Spirit Energy is continuing to drill the 43/12a-3 Andromeda North exploration well, which spudded on 29 July with the Noble Hans Deul jackup. According to the JV, the well is targeting volumes of 40 bcf in the Carboniferous, which in the event of success will be incorporated into the adjacent Pegasus development. IOG has now completed operations at its 48/24b-6 Harvey appraisal with the Maersk Resilient jack-up rig which moved off location on 19 September. As reported last month, the well encountered the top of the Leman sandstone at 7,086ft (2,160m), which was found to contain a 49ft (15m) gas column. UK ONSHORE The West Newton A-2 appraisal well was spudded on 26 April 2019 targeting the Permian Kirkham Abbey Shoal gas discovery and Cadeby Reef oil prospect. The well was initially reported as having encountered a 65m (213ft) hydrocarbon column in the Kirkham Abbey Shoal Formation with a 20m (66ft) gas column and 45m (148ft) oil column. Due to the potential of a significant oil column,

the EWT of the Kirkham Abbey Shoal Formation, that started on 24 August, was temporarily suspended on 29 August to revise the test design. Pre-drill, the Permian Abbey Shoal gas discovery had estimated P90-P50-P10 resources of 95 - 189 - 376 bcf and this will be updated based on the well results. There are plans to drill two further wells on the structure in H1 2020. Four further wells, Springs Road1, Horse Hill-1 and -2 and Preston New Road -2 are active. Springs Road-1 encountered three shale targets on prognosis with indications of gas at each interval and has undergone a comprehensive logging and core analysis program that has had encouraging results. IGas plans to drill a horizontal appraisal well and obtain permissions for a fraccing programme. The long-term production testing at Horse Hill-1 was switched from the Portland Sandstone back to the Kimmeridge Limestones in July. The Horse Hill-2 well spudded on 29 September and will drill a 1,000m horizontal section in the Jurassic Portland sandstone. Cuadrilla’s Preston New Road-2 started fraccing operation on 15 August, however micro-seismic events have caused the OGA to declare an indefinite suspension of fraccing of the well since 26 August. Cuadrilla plans to flow test the well but have removed fraccing equipment even though the full programme was not carried out. NORWAY To date in 2019, 34 exploration wells and four appraisal programmes have completed in Norway. At the time of writing, five exploration wells and one appraisal well were active. Repsol Norge spudded the 54 PESGB November 2019

Kathryn exploration well 9/2-12 on 28 September using the Scarabeo 8 semi-submersible. The well is targeting the Middle Jurassic Sandnes Formation near the Yme field. The JV is targeting low-base-high resources of 6 - 24 - 48 mmboe and the well has an estimated dry hole duration of 29 days. Aker BP spudded appraisal well 25/4-14 S with the Deepsea Stavanger to the east of the Alvheim field to de-risk infill well opportunities. The well was sidetracked on 10 September and again on 17 September before being abandoned on 22 September. A result has yet to be confirmed. Equinor’s Gladsheim exploration well 32/4-2 was spudded on 9 September, then re-spudded as 32/4-3 S on 23 September. It is targeting the Upper, Middle and Lower Jurassic and Triassic to the southeast of the Troll field. The well is being drilled with the West Hercules and is a firm commitment on this APA 2017 Round licence. Partner Lundin has reported gross pre-drill resources of 96 mmboe. ConocoPhillips spudded the Busta exploration well 25/7-7 on 29 August with the Leiv Eiriksson semi-submersible. The well is targeting pre-drill resources in the range 54 - 199 mmboe in Upper Jurassic Intra-Draupne Brae-equivalent sandstones and has an estimated duration of 74 days in the dry hole case. On 30 August Aker BP spudded its Kark exploration well 2/1-17 S with the Maersk Interceptor. The well is targeting Upper Jurassic Ula Formation prospectivity south of the Gyda field with secondary targets in the Upper - Middle Jurassic and Triassic. Pre-drill resources are reported by the operator to be in the

range 15 - 48 mmboe and the well has an estimated duration in the region of 68 days. In the Norwegian Sea PGNiG spudded its first operated well in Norway on 30 August, targeting predrill resources in the range of 10 - 22 mmboe in the Middle Jurassic, Garn Formation, Shrek prospect. The well has secondary objectives in the Upper, Middle and Lower Jurassic. The well was sidetracked on 28 September. Equinor’s 6407/3-2 S Lanterna exploration well was spudded on 6 August with the West Hercules rig targeting oil in the Middle - Lower Jurassic Fangst and Båt Groups on the western Trøndelag Platform with secondary prospectivity in the Upper Triassic. The well was testing a new migration pathway from the Halten Terrace across the Bremstein Fault Zone onto the Trøndelag Platform but failed to find hydrocarbons and was abandoned as a dry hole on 5 September. Equinor spudded its Ørn prospect 6507/2-5 S exploration well on 23 July targeting the Middle - Lower Jurassic with pre-drill resources of 8 - 40 mmboe with secondary potential in the Cretaceous. The well was successful in making a commercial gas discovery in the primary target with resources of 300 - 528 bcf. The Skarv field infrastructure lies less than 20 km to the southeast and this is expected to be the most likely tieback host. On 31 May, OMV and partners DNO, Equinor and Spirit Energy spudded appraisal well 6506/11-11 S with the Deepsea Bergen targeting the Middle Jurassic and Lower Cretaceous Iris and Hades discovery made in 2018 with well 6506/11-10. Mid case resources are estimated at

N E W S F E AT U R E

640 bcf gas and 26 mmbbl liquids (133 mmboe). The initial well is expected to have duration of between 75 and 120 days, depending on the result, and is ongoing at the time of writing. There is an option for a sidetrack well which will extend the total duration to around 178 days. In the Barents Sea, with the completion of Equinor’s 7324/6-1 Sputnik exploration well in July, which was abandoned as a minor oil discovery, there is no current drilling in the Barents Sea.

Greenfield sanctioning to support production growth in the Gulf of Mexico

Production from the US offshore has been growing over the last five years primarily as a result of low decline rates on mature fields and a focus on infill drilling. Going forward, the region’s supply is expected to be supported by the sanctioning of new projects, as operators invest into the increasingly more competitive deepwater developments. This article assesses the outlook for the United States offshore, illustrated by three key drivers: supply, resource potential from new projects and capital investments. Figure 1 shows total production from the United States Gulf of Mexico (GoM), from 2010 to 2025. Production in the region has been growing since 2014, reaching around 2.3 million boe/d in 2018 (almost 80% oil). Deepwater volumes accounted for around 85% of the total production last year. Low decline rates on mature fields driven by infill drilling activity have contributed to the production growth. Moreover, the offshore landscape in the United States had historically been dominated by the majors, and the share of production operated by BP, Chevron and Shell is expected to surpass 50% going forward. This year, production is expected to grow to nearly 2.4 million Olga Kerimova, Vice President olga.kerimova@rystadenergy.com

Amid depletion in conventional onshore reserves, the deepwater segment becomes more important than ever, taking a significant share in majors’ portfolios. Specifically, offshore deepwater developments in the region constitute about 20% of majors’ total remaining reserve base. Overall, Rystad Energy expects offshore sanctioning to increase in the medium term with Gulf of Mexico being one of the primary contributing regions. We thus estimate growth in investments in this sector, which in the longer term will have a positive impact on production and revenues of both E&P and OFS companies.

The spending levels are forecasted to stay around the same level next year and to start growing from 2021 when new projects are expected to see growing investments. Significant contributions will come from recent deepwater discoveries, including Ballymore (2018) and Whale (2017), as well as the 2014 Anchor and Leon discoveries. The Ballymore field was discovered by Chevron and Total in September 2018 and is slated for sanctioning for the second half of 2021. The final investment decision on the Anchor development is expected later this year or early next year. The growth in investments post 2023 will be supported by the sanctioning of the Tiber (BPoperated) and Dover (Shell-operated) fields, as well as exploration potential from awarded acreage. CONCLUSION Production in the Gulf of Mexico region has been on increasing trend since 2014 and is estimated to reach 2.4 million bpd in 2019. One of the industry lowest decline rates on mature fields have been supporting the production in the region to date. In addition, in the medium term we expect greenfield sanctioning to pick up, which is expected to drive production growth in the Gulf of Mexico in the future.

Kosmoss Energy l Company Profile Kosmos Energy is a full-cycle deepwater independent oil and gas exploration and production company focused on the Atlantic Margins. The company’s key assets include production offshore Ghana, Equatorial Guinea and U.S. Gulf of Mexico, as well as a world-class gas development offshore Mauritania and Senegal. Kosmos also maintain a sustainable exploration program balanced between proven basin infrastructure-led exploration (Equatorial Guinea and U.S. Gulf of Mexico), emerging basins (Mauritania, Senegal and Suriname) and frontier basins (Cote d'Ivoire, Namibia and Sao Tome and Principe). Kosmos’ longer-cycle exploration targets under-explored or overlooked petroleum systems. Once an area of interest has been identified, Kosmos targets licenses over the particular basin or fairway to achieve an early mover or in many cases a first mover advantage. In terms of license selection, the company targets specific regions that have sufficient size to manage exploration risks and provide scale should the exploration concept prove successful. Kosmos also looks for long-term contract duration to enable the "right" exploration program to be executed, play type diversity to provide multiple exploration concept options, prospect dependency to enhance the chance of replicating success, and sufficiently attractive fiscal terms to maximize the commercial viability of discovered hydrocarbons. Reserves The Company’s proved net reserves at the end of 2018 were 167 million barrels of oil equivalent (MMBoe), including 90 MMBoe of net reserves in Ghana, 26 MMBoe of reserves in Equatorial Guinea and 51 MMBoe of reserves in the U.S. Gulf of Mexico. These volumes also include natural gas reserves of approximately 10 MMBoe, which represent the gas anticipated to be used for power generation on the Jubilee and TEN FPSO vessels and Ceiba/Okume complex, as well as gas sales from the TEN fields. Production Kosmos’ production assets include oil producing fields offshore Ghana, Equatorial Guinea, and in the deepwater U.S. Gulf of Mexico.

OVERVIEW OF OPERATIONS Equatorial Guinea In 2017, Kosmos expanded its position in the Gulf of Guinea by acquiring an interest in the Ceiba Field and Okume Complex production assets, offshore Equatorial Guinea. The Ceiba and Okume Fields, which the Kosmos team originally discovered and managed, provide low-cost, high-margin production with several identified opportunities for resource and value upside.

TEN Fields The Deepwater Tano Block is adjacent to the West Cape Three Points block in the Tano Basin offshore Ghana. Kosmos entered the block to further expand their position in the basin, capturing a leading position in this Late Cretaceous play opportunity. An appraisal well of the significant Jubilee Field discovery was drilled on the Deepwater Tano block in 2007, confirming the field as a major discovery and the Tano Basin a new petroleum system. Kosmos and partners discovered the significant Tweneboa gascondensate accumulation in 2009, followed by the Enyenra oil field in 2010. Further drilling success resulted in the discovery of oil at the Ntomme field and oil and gas-condensate at Wawa in 2012. Initial development of the discoveries on the Deepwater Tano block focused on the Enyenra and Ntomme oil fields, using a floating production, storage and offloading (FPSO) vessel.

US Gulf of Mexico Kosmos has a strong position in the Gulf of Mexico with significant – and growing – production from a range of high-margin assets. Additionally, the company are pursuing short-cycle, infrastructure-led exploration near existing facilities in oil prone areas. DEVELOPMENT

GABON

In addition to the production assets, Kosmos has interests in four exploration blocks offshore Equatorial Guinea: EG-21, EG-24, S and W. These blocks are adjacent to the Ceiba Field and Okume Complex, and provide exploration opportunities for near-field short-cycle tie-backs through existing infrastructure with good fiscal terms, as well as larger stand-alone frontier exploration opportunities.

Ghana Jubilee Field Kosmos opened a significant new hydrocarbon province, the Tano Basin, with the discovery of the Jubilee Field offshore Ghana in 2007.

Kosmos served as Technical Operator for Development at Jubilee. The Jubilee Field development was designed in a phased approach to bring first production on quickly and to apply early findings to follow-on phases. First production came in late 2010, just three and a half years from the initial discovery, a record timeframe in deepwater FPSO developments.

Production from Tweneboa, Enyenra, and Ntomme (TEN) began in 2016.

Okume Ceiba

The Jubilee Field straddles both the West Cape Three Points and Deepwater Tano blocks. Success at Jubilee was the result of the company’s identification of the overlooked Upper Cretaceous structural-stratigraphic play concept along the Transform Margin of Africa.

Kosmos’ development projects include the world-class Greater Tortue natural gas field offshore Mauritania and Senegal.

Mauritania The company's position offshore Mauritania is a significant extension of the core Cretaceous theme along the West Africa Transform Margin that Kosmos confirmed in the Tano Basin offshore Ghana. The company’s acreage is located in the Mauritania salt basin, where industry results confirm the presence of a working petroleum system and the potential for both oil and gas-condensate. Successful Exploration To date, Kosmos has drilled several successful wells offshore Mauritania.

Kosmoss Energy l Company Profile Tortue-1 and Ahmeyim-2 were drilled in the southern part of block C8 and made important discoveries in the Greater Tortue area. Kosmos also made another major gas discovery in the northern part of block C8 when their Marsouin-1 exploration well encountered gas, representing a significant, play-extending find.

As an extension of the Tano Basin in Ghana, which the Kosmos exploration team opened with the Jubilee discovery in 2007, offshore Cote d'Ivoire is an opportunity for Kosmos to execute a frontier/emerging basin exploration strategy and pursue new technical themes.

In October 2018, Kosmos entered into a strategic exploration alliance with Shell Exploration Company to jointly explore in Southern West Africa. Initially the alliance is focusing on Namibia, where Kosmos has acquired interest in Shell-operated block PEL 39. As part of the alliance, the two companies will also jointly evaluate opportunities in adjacent geographies. This alliance is consistent with Kosmos’ strategy of partnering with supermajors to leverage complimentary skill sets. Shell has deep expertise in carbonate plays, while Kosmos brings significant knowledge of the Cretaceous in West Africa.

São Tomé and Príncipe SENEGAL

Senegal Acquired in August 2014, Kosmos's acreage in Senegal is adjacent to, and on trend with, the company's blocks in Mauritania. It offers a significant Cretaceous play extension opportunity and enables integrated exploration of the deepwater part of the Senegal River Basin. To date, Kosmos has made three important discoveries offshore Senegal: Guembeul, Teranga, and Yakaar. The Guembeul discovery in the Saint Louis Offshore Profond block, helped to delineate the size of the Greater Tortue resource. The Yakaar and Teranga discoveries in the Cayar Offshore Profond block confirmed that a prolific inboard gas fairway extends approximately 200 kilometers from Mauritania through the Greater Tortue area on the maritime boundary into Senegal. Together, the Yakaar and Teranga discoveries create another potential hub for natural gas production in the region. In September 2019, Kosmos reported that the Yakaar-2 appraisal well encountered approximately 30 meters of net gas pay in similar highquality Cenomanian reservoir to the Yakaar-1 exploration well, continuing the 100 percent success rate of wells targeting the inboard Mauritania/Senegal gas trend. Yakaar-2 was drilled approximately nine kilometers from Yakaar-1 and proved up the southern extension of the field. The results of the Yakaar-2 well underpin the company's view that the Yakaar-Teranga resource base is world-scale and has the potential to support an LNG project that provides significant volumes of natural gas to both domestic and export markets. Partners in the Yakaar-Teranga gas project, located offshore Senegal, include PETROSEN, BP, and Kosmos.

EXPLORATION Kosmos is expanding its exploration portfolio with choice positions in proven, emerging and frontier basins along the Atlantic Margin.

Cote d'Ivoire In late 2017, Kosmos acquired five blocks offshore Cote d'Ivoire as part of its return to the Transform Margin of Africa and the Gulf of Guinea to pursue second-cycle exploration opportunities.

From 2015-2018, Kosmos took advantage of the industry’s downturn to build its exploration portfolio. Kosmos' acquisition of acreage offshore Sao Tome marked a strategic re-entry into the Gulf of Guinea, an area we know very well and which provides an opportunity to pursue the core Cretaceous theme that was successful for the company in Ghana.

Suriname In December 2011, Kosmos secured a position offshore Suriname, marking their first portfolio expansion beyond Africa. This position provides an opportunity to explore the Upper Cretaceous stratigraphic play type along the northeast margin of South America. Industry results in the same geographic region, the Suriname-Guyana Basin, have proven the potential for significant hydrocarbon discovery.
