A word from the President



Time to Strike a Balance Am I a male, pale and stale President? With a couple of very notable exceptions, the PESGB President role has been occupied mostly by people characterised through various parameters as “least diverse”. There have only been two women presidents of the Society since 1990 (for the record, Rosemary Johnson Sabine in 1994 and Oonagh Werngren in 2014). Whilst we could rightfully claim that this is not our faults, the past president, president-elect and I clearly perpetuate this situation. The gender balance of the PESGB membership is approximately 77% men and 23% women. Similarly, the PESGB Council is comprised of 66% men and 33% women. It doesn’t take a rocket scientist* to work out why. The oil and gas industry since its inception has been a predominantly male environment. During my geology undergraduate years in the late 1980s, the course was majorly populated by men. The balance across university education has radically shifted in recent years, with many more women entering industry. And yet it remains stubbornly difficult to break an overwhelming patriarchy. Gender disparity has recently become more transparent in the UK with the legal requirement for larger organisations to report on pay. My own employer reported at the end of 2017 and made headlines as one of the first to do so. Whilst the principles of “equal work means equal pay” were clearly upheld (unlike other commercial sectors), there was a gender pay gap apparent, particularly in higher job grades. This was clearly due to the lack of women in senior

roles and the legacy of bias in science/engineering-based careers. The historically male domain of offshore work has skewed the gender pay gap in particular. I was talking to a work colleague the other day and asked her why she thought there were not more women in senior roles in the oil and gas industry. Two hours later, I returned to my desk to find an elaborately hand-drawn diagram, highlighting a multitude of factors across a hypothetical career timeline. The burden of traditional roles, international mobility, reputation, perception, behaviours, stress, competitiveness following parental leave, availability and affordability of child-care, intra-gender competition… a veritable minefield of challenges. Of these, bridging or breaking the traditional parenting gap and enabling career continuity is critical, although this has been impeded by the recent industry downturn, where continued employment is biased towards those who are flexible and mobile (typically men, in other words). So – with media headlines and the positive messages emanating from International Women’s Day still ringing in our ears – there is still much to be done to ensure equality and the right person, with the right skills, gets the right job, and on the same pay. The PESGB will continue to play its own role in ensuring that we provide opportunity to all. As a start, I hope that all members feel empowered to stand for a 2019 Council role. As part of the PESGB GEOLiteracy programme for 2018, we are very pleased to have Professor Joanna Morgan from Imperial College take on the unenviable task of presenting a mass extinction event. Her work with colleagues on the coring programme in the Chicxulub impact crater of Mexico has changed views on the way this +/- 66-millionyear-old event effected Earth’s life systems. We look forward to engaging a new community of potential geoscientists with some stimulating lectures. There are sponsorship opportunities for individuals and companies, so we would welcome your participation in return for a certain level of immortality. Check the PESGB website for more details. Finally – a hearty congratulations to our PESGB office team. Last month, Maria and her team were awarded two European Association Awards, with a silver medal for “Best National Association” and a bronze award for “Best Membership Initiative”, which recognised our 2017 GEOLiteracy outreach programme with Professor Ken Lacovara. This was an amazing achievement and testament to what a small team can achieve on behalf of you, our members. Feedback welcome.

Piecing together a Picture The Petroleum Detective Approach With Brian Moffatt, Petrophase In the Exploration and Production industry we view technical challenges through the lens of our home discipline; we say biomarkers lie in the domain of geochemistry while oil properties and reserves estimation belong in the realm of petroleum engineering. However, Mother Nature sprinkles her clues indiscriminately across all disciplines so many technical problems refuse to sit neatly in a single domain, indeed the expertise from several may be needed to understand the placement and properties of petroleum. A different perspective may be taken by a Petroleum Detective. The good detective questions the data and gathers evidence from a wide variety of experts to build a credible and defensible case. He doesn’t just round up the usual suspects! Several high profile studies solved with this approach are being revealed in this talk, some presented for the first time. The case studies include: • Determining how a strange heavy oil was formed at high pressures in a stacked system of different oils and condensates revealed the filling mechanism and type of petroleum at shallower and deeper depths. This gave clues for further

exploration opportunities. The solution needed isotopic data, phase equilibria, Petrophysics and Geochemistry but was beautifully simple in concept and furnished both reservoir engineering data and exploration data, while explaining the compositions, properties and overpressure. • Evolution of heavy oil by gas stripping • How different disciplines viewed mercury contamination in an HPHT reservoir and how these could be reconciled as different facets of the same phenomenon. • How the mystery of the lateral concentrations of hydrogen sulphide and carbon dioxide in the Buzzard reservoir were solved and how this could be used to predict concentrations in an undrilled reservoir. All the case studies share an unexpected feature. Far from having multiple disciplines making the problems more complex, the solutions were invariably the simplest possible. It was a change in perspective that revealed them. Acting as Petroleum Detective gives unique, balanced insights and saved about $2 billion over the studies presented, mostly through clearer understanding of reservoir fluids which guided decisions on optimising recovery.



UK Shale Gas (& Oil) Exploration from 1875 to now With Dick Selley, Imperial College, London

Figure 1. Nineteenth century serendipity. The Netherfield No.1 well drilled in E Sussex in 1875 produced oil & gas from naturally fractured interbedded Kimmeridge shales & limestones (By E. Cooke, Esq. RA.); Figure 2. Twenty-first century science. The Brockham oil field, Surrey. An old (1986) conventional oil field now re-entered in 2017 to produce from naturally fractured interbedded Kimmeridgian shales and limestones.

In 1875 oil and gas was accidentally found in interbedded Kimmeridgian limestones and shales at Netherfield, Sussex. This well was drilled purely out of academic interest and the sponsors viewed the petroleum as an inconvenient contaminant. In 1987 academic research carried out at Imperial College was published on the shale gas potential of Lower Carboniferous shales of the Midlands. In 2005 this research was extended to the Jurassic shale gas and shale oil potential of the Weald basin. These publications attracted little attention. Neither industry nor government were interested in a ‘green’ shale gas production model similar to the US Appalachian ‘cottage industry’. This view changed at the turn of the century with the development of a shale gas industry in the USA due to a combination of the appliance of science and hydraulic fracturing. In 2008 the 13th Round of UK Onshore Licensing saw several blocks awarded for shale gas exploration in the Midlands and many for gas and oil in the Weald. In 2010 DECC (Now the Oil & Gas Authority) published a report by BGS that identified prospective Jurassic, Carboniferous and Cambro-Ordovician shales. A 14th round of licensing opened in 2015 and saw the few remaining prospective blocks licensed. In the succeeding years BGS produced a series of reports with resource estimates for shale gas and oil for the Carboniferous Bowland shale of the Midlands (2013), the Jurassic shales of the Weald (2013), and Carboniferous shales of the Midland Valley

of Scotland (2015) and on the Jurassic shales of the Wessex area (2016). ‘Baby steps’ in hydraulic fracturing of the Bowland Shale of Lancashire stopped abruptly on 1 April 2011 when there was an earth tremor adjacent to a well at Preese Hall, Lancashire. Hydraulic fracturing ceased, first voluntarily, and then by government decree. One of many reports was produced by the Royal Society and the Royal Academy of Engineering in 2012. This provided the government with sufficient reassurance to lift the ban on hydraulic fracturing in 2013, though with a tightening up of planning restraints. In February 2016 permission was given to hydraulically fracture a new well at the conventional Kirby Misperton gas field. Imminent commencement of the operation is still awaited. Exploration in the Weald basin has been more exciting with significant flows of oil having been produced from naturally fractured limestone bands within the Kimmeridge Clay at Horse Hill in 2016. Tests of this Oreo CookieTM hybrid play in other Wealden wells are anticipated. There has been strong environmental opposition to the production of gas and oil from shale. It will not be known if petroleum production from UK shale is commercial until several wells have been drilled and undergone lengthy production tests. Proof of concept is still awaited 30 years after a commercial shale gas (& oil) play in the UK was first mooted. PESGB April 2018 9

The Chicxulub Impact The End of an Era




With Professor Joanna Morgan @Barcroft

Tuesday 15 May, 18.00 Cavendish Conference Centre Public lecture £15

Professor of Geophysics, Department of Earth Science & Engineering, Imperial College London 1 5 - 1 7 M AY 2 0 1 8


In 1980 Luis Alvarez and his co-workers published an article asserting that a large body hit Earth ~66 million years ago and caused the most recent mass extinction, which notably included the dinosaurs.

Wednesday 16 May, 17.30 Lyttelton Theatre, The Birmingham & Midland Institute Public lecture Free

The evidence for impact was the extraterrestrial composition of a thin clay layer at the boundary between the Mesozoic and Cenozoic Eras. This became known as the “Impact hypothesis”, and was categorically dismissed by many geologists at the time, on the grounds that only two locations had been studied and the clay layer at these sites might be atypical or just unusual but terrestrial, and that the extinction was gradual and started before the impactor hit Earth. This boundary clay has now been studied at many sites around the world and is clearly formed from impact ejecta – material from the asteroid and impact site that has been ejected around the globe. Studies of small fossils in marine sediments, for which the fossil record is more reliable due to high numbers, show that life was thriving and the oceans productive immediately before impact and collapsed precisely at the boundary clay layer. The cause of the extinctions is still not widely agreed, but it is fairly certain that the impact triggered a nuclear winter – an extended period (3-14 years) when the entire Earth was cold and dark, which is likely to have been catastrophic for photosynthetic life.

It took over 10 years to find the impact site – the crater is buried beneath the surface of the Yucatán continental shelf, Mexico, and has a minimal surface expression. Geophysical methods have been used to image the crater and determine its size (~200 km in diameter) and structure. In 2016 we drilled into the impact crater to investigate large crater formation, recovery of life at the impact site (ground zero), habitability of the crater, and improve estimates of the climatic effects of this impact.

GEOLiteracy 2018 builds on the phenomenal success of the 2017 programme which engaged over 1500 people, of whom over 50% were not members of the Society, but members of the public. This year we are inviting the membership to support the initiative via Crowdfunding. Supporters will be acknowledged in a commemorative programme to be circulated at the lectures in London and Aberdeen.

Meet in the evening before the first field day to discuss the local geology and arrangements for the weekend. The location of this session will be at the Macphail Centre, Ullapool at 8pm. Scientists believe that a large meteorite hit this region about 1.2 billion years ago.



D AY 2 - S AT U R D AY 2 J U N E 2 0 1 8 The North West Highlands are home to some of the best kept secret beaches in Europe. Day two will start at Achmelvich beach, where colourful outcrops of Lewisian gneiss are punctuated by Scourie Dykes formed as magma intruded into the gneiss half a billion years ago. Learn to recognise the chemical and thermal processes recorded in the rock and the difference between metamorphic and igneous types. In the afternoon you will travel North to Clachtoll and Stoer, another of the white sandy beaches. See the ‘split rock’ and explore the fossils left behind by some of the earliest life on Earth. Visit the ‘Stac Fada’, the site where geologists have recently uncovered evidence of an ancient meteorite strike.

D AY 3 - S U N D AY 3 J U N E 2 0 1 8 Guided excursion to Knockan Crag National Nature Reserve where you will learn the story of the NWH Geopark’s eight major rock types and the history of mountain building theory in the company of local geologist, Pete Harrison. The centre has interactive exhibits in a solar powered turf roofed building which slots sympathetically into our stunning landscape. Take in views over some of the most spectacular mountains, Cul Mor, Cul Beag, Beinn Mor Coigach and the iconic inselberg Suilven and hear their 1.2 billion year old story. From Knockan Crag NNR you will travel to Loch Assynt where the road snakes round the lochside. A fortuitous side-effect of road-building was the exposure of excellent geological sections through most of the major rock types in the area. See the unconformity between 3 billion year old Lewisian gneiss and 1.2 billion year old Torridonian sandstone and marvel at where the missing time went! This is a perfect location to begin to recognise rock types in the field and read the landscape. Helmets and hi-vis jackets provided.

The Old Red Sandstone at Crawton, Aberdeenshire Led by Simon Gould, Mearns Geoscience Ltd. Saturday 19 May 2018

This field trip will examine the section at Crawton on the Aberdeenshire coast. The gently dipping coastal exposures allow inspection of the interaction between basaltic lava flows and fluvial conglomerates of the early Devonian Dunnotar-Crawton Group. The conglomerates are extremely coarse-grained, containing boulder-sized clasts within a coarse-grained, sandy matrix. Within the conglomerates, sandy barforms and channel fills are occasionally seen. Four basaltic lava flows punctuate the sequence, and are characterised by large, lath shaped phenocrysts of feldspar, and vesicles filled with calcite and quartz cements. Good examples of columnar jointing are also seen in vertical and bedding plane sections. Overlying the lavas, conglomerates and sandstones of the Abuthnott-Garvock group are exposed in a cliff section, allowing inspection of the lateral and vertical architecture of this coarse-grained alluvial system. Crawton is located 5 miles south of Stonehaven, just off the A92. The fieldtrip will examine exposures within the bay, and the walking distance covered will be less than a mile. Some localities require ascent and descent of short, steep, grassy cliff slopes. In addition, rocks within the intertidal zone on the beach may be slippery. The trip would be of interest to those working on continental alluvial reservoirs in the subsurface, but is mainly intended as an informal trip to discuss some of the local geology of Aberdeenshire.

Run by Ian Longley & Peter Ballie Visit for further information South East Asia is probably the most tectonically complex geological province on the planet and is characterised by numerous (30+) small boutique, mostly Tertiary-aged basins. The complex nature of the basins, the extreme variation between oil-prone and gas-prone basins and the dominance of ephemeral non-marine charge systems, combined with the local politics and geography, offers a diverse set of opportunity types which are potentially attractive to both large and small exploration companies alike. OBJECTIVES OF THE OVERVIEW COURSE •

The full PGSEA course that takes five (very) full days has a 30 year pedigree and has been attended by 1500+ geologists. This cut-down, two-day overview version of the course is intended to focus on the regional aspects of the petroleum systems, the tectonic evolution and the distribution of conventional oil and gas resources within the region. It also addresses the current and future hydrocarbon activities in the region and discusses future potential exploration hotspots and emerging plays.

W H O S H O U L D AT T E N D ? • • • •

Exploration managers and new business exploration staff managing diverse portfolios and/or looking for new opportunities in the region Exploration geoscientists including junior and recent experienced expats or new hires to the exploration industry working on assets in the region Senior national staff geologists who wish to broaden their understanding of plays in adjacent countries Any national geoscientist working in a basin close to a political border.

It is assumed that all students will have a basic understanding of petroleum geology, petroleum systems and modern hydrocarbon exploration methods i.e. seismic and drilling technologies etc. OUTLINE Regional Overview Introduction – Geography and Recent History Tertiary Evolution Models Overview Petroleum Systems Overview Regional Exploration History Review Recent Significant Discoveries

Richard Fox, FEPC PETEX Director We had a very successful PETEX 2016 but there is no doubt it was challenging as the industry adjusted to a low oil price environment. This time round, the oil price is higher and business confidence is increasing. The future is looking a lot brighter. The past couple of years have given us the opportunity to learn from and digest peopleâ&#x20AC;&#x2122;s ideas so that we can, deliver value, maintain affordability, present an exciting technical programme, showcase new technology and keep it fun. The good news is PETEX 2018 is now fast approaching â&#x20AC;&#x201C; and we are coming back to Olympia in central London. We have three dedicated organising committees (Technical, Business and Visitor Experience) working hard with the YPs and PESGB office staff. This new structure enables many more people to become involved. Our aim is to deliver an enjoyable, high quality event that showcases state of the art technical content and gives companies, universities and individuals an opportunity to showcase their latest thinking. Please help us deliver this vision. Get involved, submit an abstract, book floor space, plan to attend, and help us build upon the growing sense of optimism that is emerging in our industry. 22 PESGB April 2018

PETEX 2018 exhibition space is now open For more information, or to book a booth please contact or visit 26 PESGB April 2018

66 66 66

Kept exhibitor costs at 2016 rates – as we come out of this downturn together, we wanted to ensure PETEX was still accessible to you Exhibitor badges – exclusive to exhibitors, it helps you get your booth staff in at a more reasonable rate. They are designed to supplement your complimentary exhibitor passes. Guest passes – each exhibitor will be given 10 complimentary guest passes for clients to be used on the Thursday. Those individuals can join in the Technical conference on Thursday also. Moved to Olympia: transport, hotels and refreshments are all more reasonably priced. We are surrounded by bars and pubs and walking distance to Earls Court. Meeting rooms onsite – should you need them for meetings with clients, we can provide them Speakers get complimentary tickets to attend all three days of the show. We’ve moved show suppliers from Freeman’s to Showlite, they’re promising lower costs for extras that you may need on your stand.







We’ve moved to the National Hall, Olympia. You spoke, we listened. It is a fantastic bright venue, with high ceilings and great character. Transport is much more straightforward. Kensington Overground is right next door, High St Kensington tube is 5 mins away and we are within walking distance of Earl’s Court. Given that, it’s now much simpler for companies to send staff in for the day and not have to pay hotel rates. Conference and exhibition in the same hall, separated by a set of stairs (which can be branded) You’re dealing with the PESGB office, (and we’re all really nice). We’ll make the whole process as easy for you as possible! To those exhibitors who don’t have the time to produce a stand but still want to make an impact, our new show supplier Showlite can provide full panel printing and basic booth design. We can also recommend a very good stand builder if you need one!

A full list of sponsorship opportunities are available at AUDIENCE 66

Advances in Production Geoscience as an enabler for maximising economic recovery and ensuring a future for the UKCS 5-7 June 2018 Robert Gordon University, Aberdeen

Jon Gluyas University of Durham Cliff Lovelock Shell UK Limited John Underhill Heriot Watt University Confirmed Keynote Speaker: Al Tucker Brent Asset Manager, Shell

Out of adversity comes opportunity. A significant change is required in the North Sea petroleum industry to keep it profitable and growing, and geoscience has the opportunity to lead the way in delivering this change. New plays, fields, technologies and alliances are required in order to increase recovery and reduce the cost of delivering hydrocarbons. In 2014 the Maximising Economic Recovery UK report suggested that 12-24bn barrels of oil equivalent remained to be produced from the North Sea. This conference aims to show how geoscience is helping to develop and recover as much of this remaining hydrocarbon as possible. It will showcase the range of solutions maximize economic recovery from the UKCS. Specific themed sessions may include: • Near Field Exploration • New field developments • Short radius sidetracks • Infill drilling • Production from secondary reservoirs • The value of surveillance • Existing infrastructure - hosts for new opportunities, making it last longer, novel maintenance, alternative uses (wind/CO2 disposal)

• Shallow gas (fuel source) and water (for injection) • Novel drilling technology as an enabler for difficult geology • Exploiting difficult fluids • Use of new technology or first application of technology to the UKCS • Enhanced Oil and Gas recovery • Adding value from co-produced fluids • Decommissioning

The focus of the meeting will be on Geoscience, Reservoir Engineering and Petrophysics with the recognition that successful integration across the subsurface and surface disciplines is at the heart of a successful shift in future fate of the UKCS.

Chasing the Triassic Continental Sandstone Play Fairway across NW Africa Characteristics, Challenges and Opportunities With Professor Jonathan Redfern, University of Manchester Thursday 19 April 2018, 7pm Herdman Lecture Theatre, University of Liverpool During the breakup of Pangea, Triassic rift basins developed across North Africa, filled by thick sequences of continental red beds. These sequences comprise ephemeral and perennial fluvial sandstones, aeolian sandstones, alluvial fan conglomerates, playa, floodplain and lacustrine mudrocks. Toward the end of the Triassic many basin experience a transgression with deposition of marine limestones and mudstones, and where the palaeogeography and climatic conditions were conducive, thick sequences of evaporites were deposited that act as a regional super-seal. This interval forms an important reservoir across North Africa, with over a billion barrels discovered in Algeria, Libya and Tunisia. The Triassic system is now being actively explored in Morocco, with the recent Tendrara wells drilled by Sound Energy testing gas from Triassic sandstones, extending this play fairway to the west. There are many other Triassic rifts along NW African margin where a similar play exists, some undrilled, whose prospectivity is unknown The talk will review our understanding of the controls and characteristics of the main depositional systems, reservoir distribution and quality, source and seal and implications for the petroleum system. We will discuss challenges for exploration and development and the opportunities for this play along the NW Africa margin.

PESGB win two awards at the European Excellence Awards

The European Association Awards recognise excellence and exceptional quality delivered by associations across Europe. At the 2018 ceremony in Brussels, the PESGB was awarded Silver for the ‘Best National Association’. The organisation was particularly commended for supporting unemployed members through the industry downturn by providing a regular support forum for members based in Aberdeen and London, by providing low cost courses and giving concessionary rates to events. The judging panel commented: “The Petroleum Exploration Society of Great Britain (PESGB) has a strong relationship with its membership. Their feedback is important to them and they take it into consideration while recommending new activities and programmes.” “A dynamic approach with an unusually rapid reaction to the changing external environment. Particularly stimulating is the approach of offering training and interviewing to out of work staff from the industry.” “Great recovery from a tricky spot. True test of an association.” The Society’s public outreach initiative GEOLiteracy 2017 was awarded Bronze for ‘Best Membership Initiative by an Association’. The tour headlined by TED Speaker, Professor Ken Lacovara of Rowan University engaged over 1500 attendees in seven locations across the country. 2017 was a stepchanger with an unprecedented level of public engagement. We hope to carry on the momentum of this outreach campaign with future initiatives, but a new benchmark was certainly set this year. The judging panel commented: “An interesting approach and lovely innovation.” Additionally, the PESGB’s revamped website was recognised as a finalist in the ‘Best Association Website’ category. The judging panel commented: “A very comprehensive website. Creative, and educative content; nice visuals that are information driven.” “Audience targeted and well-identified.” We hope that you agree that the Society has adapted to meet the needs of its members during this difficult time and that it continues to deliver an exceptional quality service to our community.

SEMINAR: Seismic Imaging of Salt Structures: Some Pitfalls and Interpretation Guidelines With Ian Davison, EarthMoves Wednesday 18 April 2018, 6.15pm IHS Markit Global Headquarters, 25 Ropemaker Street, London, EC2Y 9LY Seismic imaging of evaporite bodies is notoriously difficult due to the complex shapes of steeply dipping flanks, adjacent overburden strata, and the usually strong acoustic impedance and velocity contrasts at the sediment-evaporite interface. This talk will review the geology of salt bodies, salt composition and internal structure and the problems and pitfalls associated with salt imaging such as complex ray paths, seismic velocity anisotropy, P- and S-wave mode conversions, and reflected refractions. Seismic examples will be used to illustrate well failures which could have been avoided, and where new or betterdefined prospects have been generated by careful velocity analysis and processing. Some recent developments in seismic acquisition and processing will be outlined, which have led to significant improvements in seismic illumination, and image quality; in particular, reverse time migration, larger source bandwidth and OBN surveys.

SEMINAR: Career Changers – From Petroleum Geologist to… Tuesday 19 June 2018 Petroleum geology is a great career - but we all know the industry has its ups, and more recently, its downs. As a result many were out of work and graduate recruitment came to a halt. If you want to learn how your skills as a petroleum geologist can be used elsewhere come along to this talk to hear how some ex-petroleum geologists have done just that. If you can’t find that coveted graduate geologist job, just fancy a change in career or keen to explore (pardon the pun!) what other petroleum geologists have gone on to do outside of oil and gas then join us for some inspiring talks!

African discoveries prior and post the 2014 oil crash Between the start of 2012 and the end of 2017 some 42 Billion barrel oil equivalent (Bboe) were discovered in Africa and some 1,700 exploratory wells were drilled. This article describes the resources split between the three years prior to the 2014 oil price crash (start 2012 to end 2014 or initial period) and the three years after (start 2015 to end 2017 or second period). Where were the most prolific African regions in terms of added resources and exploratory drilling? How Africa compares with the worldwide top 10 discoveries over the studied period? Did the oil price crash significantly impact the exploration drilling activity? RESOURCES In Africa some 42 Bboe of resources were discovered between 2012 and 2017. Just less than two thirds were discovered in the three years prior to the 2014 oil price crash, when within a six month period, the oil price fell from around USD 100 per barrel to less than USD 60 per barrel. Between the beginning of 2012 and the end of 2017, the resources

discovered in Africa were primarily gas (33.2 Bboe of gas vs 8.7 Bbo of liquids). Specifically, 74% of the hydrocarbons discovered during the initial period were gas, a proportion increasing to 89% in the second period. Between 2012 and 2014, some 26 Bboe were discovered in Africa. Out of which, 61% was discovered in East Africa (primarily in Mozambique and Tanzania). West Africa contributed to

27%, with the largest discoveries located in Nigeria, Angola, Congo and Gabon (Fig 1). For the second period, the picture is slightly different. North West African countries emerged (Mauritania and Senegal) and hosted 48% of the added resources, followed by North Africa with 30% and West Africa with 17%. East Africa contributed to only 5% (Fig 1).

Figure 1. Comparison of added resources per region between 2012-2014 and 2015-2017 44 PESGB April 2018


EXPLORATORY DRILLING Based on the available data, almost 1,700 African exploratory wells (including appraisals) were drilled during the entire studied period. If outposts and new-pool wildcats are excluded, the number of wells drops to about 890. In the initial period, some 1,270 exploratory wells were drilled, of which 52% were new-field wildcat wells (NFW). During the second period, the number of exploratory wells declined by 76%. It is worth noting that the percentage of NFWâ&#x20AC;&#x2122;s drilled remained almost the same. Overall success rate was in the

range of 40%. For the initial period, 44 % of wells were successful while the rate slightly decreased to 36% in the second period. The most successful regions in the initial period were East Africa and North West Africa with success rates of over 50%. In the second period, only North West Africa had a success rate higher than 50%. In both periods, the highest number of NFWs drilled was in North Africa (Fig. 2) but the region had one of the lowest added resources per well rate in the initial and the second period; 6 MMboe/well and 30 MMboe/well

respectively. The second most active region was West Africa that added 44 MMboe/well in the initial period and 68 MMboe/well in the second one. However, in the initial period, the region with the highest added resources per well was East Africa with 228 MMboe/well. The region holds 61% of the added resources (16 Bboe) for the period with only 10% of the NFWâ&#x20AC;&#x2122;s drilled. In the second period, North West Africa added 799 MMboe/well. Only 4% of the wells were drilled in North West Africa, for 48% of the added resources.

PES African discoveries prior and post the 2014 oil crash (cont.) AFRICAâ&#x20AC;&#x2122;S BIGGEST DISCOVERIES Between 2012 and 2014, out of the 290 discoveries or so, over 30 hosted resources in excess of 200 MMboe; with 16 discoveries located in East Africa and 10 in West Africa. Only three discoveries hold resources in excess of 1 Bboe, all of which are located in East Africa and are gas. The Golfinho/Atum, Coral and Orca gas discoveries were all made offshore Mozambique in deep water, within the prolific Rovuma Basin. The combined total resources for the three discoveries is 8.6 Bboe, accounting for over half of the resources discovered in the region during the period and 33% of all the African discoveries between 2012 and 2014. Golfinho and Atum were discovered in 2012 by Anadarko in the Rovuma Offshore Area 1, but a successful appraisal programme confirmed the connectivity between the reservoirs, leading to a giant field holding 4.8 Bboe (28.6 Tcf). First gas is expected in 2020 via phased LNG development. The project includes the construction of two initial LNG trains with a capacity of 6 Million ton per annum (MMtpa) each. The project could further be expanded to 50 MMtpa, which may allow for production from the Orca giant gas field discovered by Anadarko in 2013. The Orca field is located south of the Golfinho/Atum field, and hosts 1.8 Bboe (10.4 Tcf).

The 2 Bboe (12 Tcf) Coral discovery was made by Eni in 2012. First gas is scheduled for 2021. The first development phase will include the development of 5 Tcf via a Floating Liquid Natural Gas (FLNG) facility with a 3.3 MMtpa capacity. The three biggest oil discoveries are located in North West Africa and West Africa. North West Africa held the SNE oil and gas field (Senegal) that discovered 75% of the resources in the region. West Africa hosted the Owowo West oil field in Nigeria and Nene Marine oil and gas field in Congo, accounting for 20% of the added resources in the region. Cairn discovered the giant SNE oil field in 2014 in the deep offshore Senegal (M.S.G.B.C.) Basin. Some 740 MMboe were discovered in Albian sandstones along the shelf edge of the NW African passive margin. First production is expected for 2021 with a production plateau of 100-120 Mb/d. The Owow West oil field in Nigeria was discovered by Total in 2012 and hosted about 770 MMboe. The Nene Marine oil and gas field was discovered by Eni in 2012 in Congo. It tested the Lower Creataceous Djeno sandstones in a pre-salt structure within the Lower Congo Basin. The field hosts some 650 MMboe (390 MMbo of liquids and 260 MMboe of gas).

Table 1: 2012-2017 top ten discoveries (as of early January 2018) 46 PESGB April 2018

In the second period, about 10 discoveries (out of a 100 or so) were larger than 200 MMboe. Three discoveries contributed 59% of the resources discovered in Africa during the period. The biggest discovery was Zohr in Egypt (North Africa) followed by Ahmeyim/Guembeul (Tortue) on the Mauritania/Senegal border and Yakaar in Senegal (North West Africa). The Zohr gas field was discovered by Eni in 2015 in the Mediterranean deep waters at the junction of the Eratosthenes High and the Nile Delta Basin. It hosted 3.6 Bboe and accounted for 80% of the discovered resources in North Africa during the period. Eni tested a new play concept based on the presence of Lower Middle Miocene and Lower Cretaceous carbonate reservoirs. Gas is set to flow at an initial rate of 350 MMcf/d, with production expected to increase to 1 Bcf/d in June 2018 and to 2.7 Bcf/d by the end of 2019. The Ahmeyim/Guembeul (Tortue) and Yakaar gas fields are both located in the deep water offshore Senegal (M.S.G.B.C.) Basin and were discovered by Kosmos. The two discoveries host 74% of the resources discovered during the period in North West Africa. Kosmos discovered the 2.7 Bboe Ahmeyim/Guembeul field in 2015 by testing a Cretaceous fan

structure. First gas is expected in 2021 from the first FLNG facility and in 2023 from the second FLNG. The Yakaar gas discovery was made in 2017 by the Kosmos/BP joint venture, using the same exploration concept as for the Ahmeyim/Guembeul field and hosted 2.7 BBoe. AFRICA’S VS WORLDWIDE BIGGEST DISCOVERIES Table 1 lists the ten biggest discoveries worldwide between the beginning of 2012 and the end of 2017. Five African fields are part of the ten largest discoveries that added approximately 27.8 Bboe. About 30% of the discovered resources are added by the two biggest fields; both located in Africa (Golfinho/Atum in Mozambique and Zohr in Egypt).

The Mauritania and Senegal discoveries, Yakaar and Ahmeyim/ Guembeul, despite their sixth and seventh positions, averaged the same size as the Atapu field in Brazil and the Tulimaniq field in United States; all between 2.4 Bboe and 2.8 Bboe. The biggest oil discoveries in Africa rank in 29th and 30th position and are located in Nigeria with Owowo West with 770 MMboe and in Senegal with the SNE field containing 740 MMboe. CONCLUSION The mid-2014 oil price crash resulted in exploratory budget cuts in oil and gas companies. The companies had to refocus their exploration targets at prospects that were economically viable at less than USD 60 per barrel, leading to a significant reduction in

the number of exploratory wells drilled and as a consequence, the number of discoveries. This is well illustrated by the reduction of NFW drilled (from 660 to 290) and the amount of resources (from 26 Bboe to 16 Bboe). It’s worth noting that success rates decreased slightly in the second period (44% to 36%) however, resources added per well increased (from 40 MMboe/well to 69 MMboe/ well). This might suggest that, in the second period, exploration targeted larger prospects even if slightly riskier. Nevertheless, as described, five of the ten biggest discoveries of the studied period are located in Africa and over 30% of the resources discovered between 2012 and 2017 are located in Africa.

PES South East Asia News Rain has caused problems for Buru Energy’s final quarter 2017 results, as the company struggles back on its path towards production from its Ungani oil field in Western Australia’s Canning Basin. The field, which was only returned to production recently, was shut in for almost a month during the December quarter for the workover and recompletion of wells. While the work was completed on time and budget, the fields were only able to produce for two months before the wet season unleashed its fury, dumping 260 millimeters (10.2 inches) of rain over the field, almost half of the average annual rainfall for the area in a three-day period. A tropical low-pressure system dumped more than 400 millimeters (15.7 inches) of rain on the nearby Kimberley town of Broome in early February, close to the record daily rainfall for Broome of 476 millimeters (18.7 inches) The Australasian Oil and Gas Exhibition and Conference in March 2018 will hold another Diversity and Inclusion Breakfast to highlight the increasingly important role a diverse workforce plays in industry, with the issue now being considered at the executive level. Woodside CEO Peter Coleman said at the World Petroleum Congress in July last year that his least diverse department was human resources, which was 85% female and largely white. “Delivering superior shareholder returns depends on our ability to attract and retain a talented, engaged, diverse and high performing workforce,” a Woodside statement said. ConocoPhillips top executive Al Hirshberg said in Q1 2018, the company was “very pleased” with the progress of the Barossa development 48 PESGB April 2018

concept in the Timor Sea, and expects the project could be in frontend engineering and design before the end of Q2. Acknowledging some press chatter that ConocoPhillips and Santos were looking to develop the field as backfill gas for Darwin LNG more aggressively this year, to target first production to replace the aging Bayu-Undan field early in the next decade, Hirshberg implied a final investment decision could be taken in 2019. Hirshberg said the appraisal drilling in 2017 had delivered impressive results, a 35% increase in the 2C resource base and strengthened the field’s position as the lead candidate for Darwin LNG backfill. Wheatstone has sent its first cargo of condensate to Thailand, just a few months after owners Chevron Corporation, Woodside Petroleum and Kuwait Foreign Petroleum Exploration Company (KUFPEC) shipped the first LNG cargo to Japan in October 2017. China’s gas imports and oil imports sped past the United States for the first time, according to the US Energy Information Administration (EIA), pushed by many factors including a concerted infrastructure expansion. The EIA report comes just as China National Offshore Oil Corporation reported its first serious increase in investment in four years, with most of the money going to develop what is an increasing global portfolio. State-owned Korea Gas Corporations is in arbitration with the North-West Shelf Venture, the first upset in what has been a longstanding energy export relationship between Australia and the world’s third largest LNG importer, South Korea. Court-based arbitration cases are by nature confidential,

but Reuters reported overnight it is based on a price dispute based on a 2016 contract with its joint venture partner. Though LNG price arbitration cases have come up in Europe it is something of a first for Asia and it could set a precedent. The Inpex-led Ichthys LNG field is facing another potential cost blowout, French supermajor Total suggested in early February 2018. It also implied that the project will not meet its end of March 2018 deadline for first production, as planned by operator Inpex, as it could slip into the second quarter. At a Paris earnings conference Total’s CEO Patrick Pouyanne said that “…maybe..” the megaproject will end costing US $40 billion, but that “…the project is moving on…” regardless. Woodside Petroleum is undertaking a A$2.5 (US $1.95) billion equity raising to acquire the additional 50% of the Scarborough gas field from ExxonMobil, which is a sign Woodside is keen to put one of Australia’s most remote gas fields on production. The purchase of ExxonMobil’s long-held gas interests will give Woodside a 75% interest WA-1-R, host to the main seven TCF Scarborough field, and a 50% interest in WA-61-R, WA-62-R and WA-63-R that cover the smaller Jupiter, North Scarborough and Thebe fields. The leases are valid until November 2020.

International News ARGENTINA Vista Oil & Gas has entered into a series of agreements to acquire a large packet of assets from Pampa Energía and Pluspetrol. Under the terms, Vista will purchase 58.9% of Petrolera Entre Lomas SA (PELSA) from Pampa and a further 39.2% stake from Pluspetrol, plus 100% of the capital stock of its subsidiary company APCO Oil & Gas. As a result, Vista will hold a majority operating stake in three Neuquen Basin concessions, plus a direct minority stake in the Entre Lomas, Bajada del Palo, and Agua Amarga concessions and 100% interest in the 25 de Mayo-Medanito SE and Jaguel de los Machos blocks in the Rio Negro Province. Once the transactions are complete, Vista will be the fifth-largest energy company operating in Argentina, with assets producing 27.5 Mboe/d (of which 60% oil) and 1P reserves pegged at 55.7 MMboe. The exact financial terms of the transactions have not been disclosed, but Vista noted that it has secured USD 800 million to fund the purchase, plus a credit facility of USD 300 million to be used if necessary. AUSTRALIA A geological assessment of the WA-521-P exploration permit in the Roebuck Basin has enabled operator Carnarvon Petroleum to estimate the total prospective resource potential at almost 1.6 Bbbl. Eight prospects have been identified, notably Ivory (formerly, Labyrinth), with a Pmean recoverable volume of 322 MMbbl in the Lower Depuch Formation, and Ivory Deep, with an estimated 99 MMbbl in the Bedout Formation. The permit covers 5,050 sq km on the North

West Shelf, directly northwest of the Phoenix South and Roc discoveries. WA-521-P was originally offered as block W15-5 in the 2015 Federal Offshore Acreage Release, and was granted for six years in March 2016. The work programme calls for various geological and geophysical studies in the first three years, followed by the acquisition of around 300 sq km of 3D seismic data in the second phase. Carnarvon holds full interest and operatorship in WA-521-P, which is also commonly referred to as the Labyrinth project, and is currently looking for a farm-in partner to advance the exploration work. Woodside has reported an agreement with ExxonMobil for the acquisition of the latter’s 50% operated interest in WA-1-R, which contains most of the Scarborough gas field. In return, Woodside plans to make an initial USD 444 million payment, followed by a secondary contingent payment of USD 300 million upon the Scarborough project reaching Final Investment Decision (FID). The transaction is subject to a number of conditions. Upon completion, Woodside will hold a 75% interest in WA-1-R and a 50% interest in the neighbouring WA-61-R, WA-62-R and WA-63-R, which also contain the Jupiter and Thebe discoveries. BHP holds the balance in all licences, as well as pre-emptive rights. Scarborough, Jupiter and Thebe in the North Carnarvon Basin are estimated to contain gross 2C gas resources of 8.7 Tcf. Current development plans call for a tie-back to the Pluto LNG facilities, with a FID by 2020 and a planned start-up around 2025. Woodside plans to raise USD 1.96 billion from shareholders, with proceeds to be used for Pluto

expansion and other operations in Australia and Senegal. CHINA CNOOC has announced plans to bring four new fields in the South China Sea onstream in 2018. The Weizhou 6-13 oil field is expected onstream in the first half of the year, followed by the Penglai 19-3 oil field in the Bohai Gulf and the Dongfang 13-2 and Wenchang 9-2/9-3/10-3 gas fields - all in the second half of the year. The state company is targeting 470 – 480 MMboe production for the year, of which 64%, or 300 – 307 MMboe, is expected to come from Chinese fields. Notably, that target represents an increase from its 2017 guidance, which projected 450 – 460 MMboe in 2017 and 455 - 465 MMboe in 2018. Total capex is budgeted at CNY 70 – 80 billion (USD 11 – 13 billion), of which 65%, or CNY 46 – 52 billion (USD 7 – 8 billion), will be allocated to development projects. CYPRUS The first exploration well in Block 6 has yielded encouraging results for operator Eni. The Calypso 1 wildcat, spudded in late December, has encountered an extended gas column in rocks of Miocene and Cretaceous age. Drilling operations were conducted in 2,074 m of water with the “Saipem 12000” drillship, ending to a total depth of 3,827 m. While no firm resource estimates have been provided, some sources mention a potential volume of 6 to 8 Tcf. However, this is early days and appraisal work is required to better define the size of the find. Most importantly, the well has proved the extension of the Zohr carbonate play into Cyprus, boding PESGB April 2018 49

well for upcoming exploration efforts. Block 6 covers 4,555 sq km in the Herodotus Basin, southwest of the island and is one of six blocks in which Eni is present. The lease was granted to a 50:50 consortium composed of Eni and Total in April 2017, following the Third Offshore Licensing Round. GAMBIA Operator FAR has signed a farm-out agreement with Petronas regarding a 40% interest in offshore Blocks A2 and A5. Under the terms, the Malaysian company will fund 80% of total well costs of the Samo 1 exploration well, to be drilled in late 2018, up to a USD 45 million cap. Based on a completion date of 31 March 2018, FAR is also to be paid an estimated USD 13.5 million to cover back costs and cash consideration. In addition, Petronas will fund the Australian company’s share of nonwell costs up to a USD 1.5 million cap. Blocks A2 and A5 are contiguous and cover a total area of 2,683 sq km in water depths ranging from 50 to 1,200 m. Two drillable prospects have been identified. Samo is on trend with the SNE oil field in the neighbouring Sangomar Offshore Deep permit in Senegal, and is estimated to contain a resource potential of 825 MMbbl in Albian sandstones. Bambo is of Late Cretaceous age and partially overlaps Samo. FAR currently holds an 80% operated interest in Blocks A2 and A5, following a farm-in agreement with Houstonbased Erin Energy in March 2017.

50 PESGB April 2018

The new transaction is subject to both government and partner approvals, and upon completion, will mark Petronas’s first foray into the Gambian E&P sector and provide it the right to become operator in the case of a development. INDONESIA The Ministry of Energy and Mineral Resources (MEMR) officially launched the 2018 conventional and unconventional licensing rounds on 19 February. The tender includes 24 conventional blocks, of which five under direct offer (South East Jambi, Citarum, East Ganal, East Papua, and East Seram) and 19 as regular tender blocks (South CPP, Nibung, Batu Gajah Dua, Air Komering, Bukit Barat, East Sokang, Banyumas, East Muriah, North Kangean, Andika Bumi Kita, Belayan, West Sanga-Sanga, Suremana I, Southeast Mahakam, Manakarra Mamuju, Karaeng, Ebuny, and Cendrawasih Bay II). Bid documents can be accessed until 27 March, with a bid deadline set for 4 April. For the regular tender blocks, interested companies are invited to submit their bids by 19 June. Licence terms include a government/ contractor split of 57/43 for oil and 52/48 for gas. The 2018 unconventional bid round includes two blocks in Sumatra under direct offer: MNK Sumut Tenggara (for shale hydrocarbons) and GMB Sumbagsel (for coal-bed methane). The bid deadline is also 4 April, with the same government/contractor split as the conventional blocks.

IRAQ The ownership of Block 9 is set to change again following a farmout agreement between operator Kuwait Energy and partner Dragon Oil. Under the terms, the former will transfer a 15% participating interest to the latter, of which 8.57% in consideration for USD 100 million in cash and the remaining 6.43% in settlement of a dispute between the two parties. The transaction is subject to government and partner approval. Upon completion, interest in the lease will be divided between Kuwait Energy, operator with 45%, Dragon Oil 45% and Egyptian General Petroleum Corporation (EGPC) 10%. Block 9 covers 866 sq km in the Basrah province, on the Iranian border, surrounded by the Azadegan, Majnoon, Nahr Umr, Sindbad and Yadavaran oil fields. Awarded in May 2012 as part of Iraq’s fourth licensing round, the tract contains the Faihaa field, which was brought online in 2015 and is currently producing approximately 18,000 b/d. Block 9 is Dragon Oil’s sole asset in the country. MEXICO The CNH-RO2-LO4/2017 Bid Round, also known as Ronda 2.4, has concluded successfully. The Comision Nacional de Hidrocarburos (CNH) announced in late January the pre-award of 19 of the 29 deep-water blocks on offer, of which nine in the Salina Basin, six in the Perdido Area and four in the Mexican Ridges Province. The newly-allocated tracts,


which cover a combined area of 44,180 sq km, received a total of 39 bids from 18 companies. Twentythree wells have been committed and total expenses relating to the planned work programmes are estimated at around USD 1.3 billion. In addition, tie-break bonus bids resulted in a total of USD 525 million offered to the state. The most successful companies were Shell, present in nine blocks, PC Carigali (6), Qatar Petroleum (5), PEMEX (4) and Repsol (3). The most disputed block was Area 29 in the Salina Basin, with five bids; a consortium led by Repsol ultimately won the contest. The 10 remaining blocks received no bids. NAMIBIA ExxonMobil is preparing to enter the Namibian E&P sector following Galp’s farm-out of a 40% interest in PEL 82. This petroleum exploration licence was granted in August 2016 and comprises Blocks 2112B and 2212A in the Walvis Sub-basin. The blocks cover a total area of 11,444 sq km in 300 to 2,500 m water depths, encompassing the Wingat 1 and Murombe 1 wildcats, drilled by Brazil’s HRT in 2013. Although both wells failed to uncover commercial volumes of hydrocarbons, the former proved the existence of a working petroleum system with some 38 42° API oil in thin-bedded sandy reservoirs, and the latter highlighted the presence of a mature Aptian source rock. The work programme for the first three-year term includes a 1,500 sq km 3D seismic survey. Once the

farm-out is effective, interest in PEL 82 will be split between Galp, operator with 40%, ExxonMobil, with 40%, and Custos and Namcor, each with 10%. This latest move marks the second foray of a major oil firm into the country since July 2017, when Total took over a 70% operated interest from Impact Oil & Gas in Block 2913B in the Orange Sub-basin. THAILAND Following the cancellation of a previous USD 900 million deal with Kuwait Foreign Petroleum Exploration Company (KUFPEC) in October, Shell announced in 31 January 2018 that it will sell subsidiary companies Shell Integrated Gas Thailand (SIGT) and Thai Energy Co (TEC) ‒ which hold a combined 22.22% in the Bongkot field and adjoining offshore blocks 15, 16, 17 and G12/48 ‒ to existing operator PTTEP. The latest deal has a value of USD 750 million and is driven by Shell’s strategy to sell non-core assets, bringing it closer to completing its ongoing USD 30 billion divestment programme. The transaction is expected to complete in the second quarter of this year, subject to closing conditions. The assets in question cover 3,200 sq km in the Malay Basin within the Gulf of Thailand. Following completion of the deal, PTTEP will hold a 66.67% operated stake, partnered with Total (33.33%). Bongkot is an important contributor to domestic production, with approximately 1.1 Bcf/d of gas and 26,800 b/d of condensate as of November.

UNITED ARAB EMIRATES Abu Dhabi National Oil Company (ADNOC) has signed an accord with Cepsa for a 20% interest in a new 40-year development contract that mainly pertains to the offshore Satah Al Razboot (SARB) and Umm Lulu oil fields. Umm Lulu has been under an early production phase since October 2014. With a yield of 25,000 b/d in the last quarter of 2017, the field is expected to produce 105,000 b/d when fully commissioned in 2020. The long-planned SARB development is underway, and the project is now anticipated to come onstream in 2018 and provide 100,000 b/d. The new lease also includes the smaller Bin Nashef and Al Batteel fields, which could be developed as satellites to the SARB infrastructure. ADNOC will retain a 60% operating interest in the concession, which will be effective on 9 March 2018, while other partners will be awarded the remaining 20%. Cepsa, whollyowned by Abu Dhabi’s Mubadala Investment Company, paid USD 1.5 billion for its 20% participation.

DRILLING ACTIVITY UNITED KINGDOM At the end of February one exploration well was active in the Northern North Sea. To date in 2018, one well has spudded and one has completed. In the West of Shetlands, there is no current E&A drilling activity. The next well that is expected to be drilled is Siccar Point’s Cambo appraisal well, for which permission was sought from the OGA in January. In the Northern North Sea, Apache spudded its Middle Jurassic Garten exploration well on 5 February with the WilPhoenix (SS). The well lies between the Beryl and Buckland fields in the Northern North Sea and is Apache’s eighth near-field target to be drilled with the aim of adding new reserves over its Beryl area infrastructure. The final E&A well of 2017 was spudded on 21 December by Apache and targeted the Upper Jurassic Val d’Isere prospect with the WilPhoenix (SS), immediately north of the Forties Field. Well 21/10b-11 however was abandoned as a dry hole towards the end of January, having failed to find hydrocarbons. The rig then moved to drill the operator’s Garten exploration well. 52 PESGB April 2018

In the Southern North Sea, there is no current E&A drilling activity. The next well that is expected to be drilled is the Andromeda prospect, close to Spirit Energy’s Pegasus development. Notification for the drilling of this well, however, has yet to be submitted to the OGA. UK ONSHORE Cuadrilla is continuing the drilling of the Preston New Road-1 well sidetrack (LJ/06-9Z), with plans to then drill a horizontal well from Preston New Road-2 (LJ/06-8). Hydraulic fracturing of both horizontal wells is expected in Q2 2018. Testing operations at the Angus Energy operated Broadford Bridge (BB-1Z) well continue and are expected to complete in March. In late February oil was flowed from the BB-1Z Kimmeridge KL5 zone. The operator is evaluating a possible sidetrack to re-test the KL3 and KL4 intervals, after completing current tests at the KL1 interval. NORWAY In February, a discovery was made at Frosk, three appraisal wells were spudded (of which one was also completed in February), two exploration wells were spudded


and one well sidetracked . There were seven active wells at the end of February, with the total number of seven well starts and five completions in 2018. On 7 February Lundin spud appraisal well 16/4-11 from the COSL Innovator, targeting the Luno II discovery to the south of the Edvard Grieg field. Following the junking of well 35/9-13 due to technical issues on 20 January, Spirit Energy spudded well 35/9-14 from the Songa Enabler targeting the Tethys prospect and it remains active. Aker BP announced that it made the Frosk (Frog) discovery with well 24/9-12 S, drilled from the Transocean Arctic, which completed on 8 February. The subsequent sidetrack was then abandoned on 25 February, having also encountered oil within sand injectites. This well is presumed to have targeted the Marihøne B (Ladybird) prospect and appraised the Frosk discovery. Statoil’s appraisal well 30/8-5, investigating the Statfjord Group within the Tune field is reported by the NPD to have been junked as a dry well on 19 February, however, results are still to be formally released. Aker BP spudded the Raudåsen 34/9-14 A well with the Songa Enabler on 28 February. On 3 February Spirit Energy spud appraisal well 6506/9-4 S, from the Island Innovator, to test the commerciality of the Fogelberg discovery made by Centrica in 2010. Well 6604/5-1 was spudded on 10 January 2018 by Wintershall using the West Phoenix targeting the Balderbrå prospect and is still active. The OMV operated well 6506/11-10, being drilled from the Deepsea Bergen and targeting the Iris and Hades prospects, was also active at the end of February. Aker BP spudded the Kvitungen Tumler prospect with the 6507/5-8 well with the Transocean Arctic on 24 February. There is no current E&A drilling in the Barents Sea, following completion of the Hurri well 7219/12-3 S in January. DEAL ACTIVITY Neptune’s acquisition of ENGIE, which was first mooted in November 2016, but was officially announced in May 2017, was reported as having completed in February. The deal brings E&P interests in the North Sea, North Africa and Southeast Asia, with total average production of 154,000 boepd in 2017. In the UK, ENGIE held interests in the Cygnus field and the Cepheus and Sillimanite

discoveries in the Gas Basin. In Norway, ENGIE held interests in the Gjøa, Gudrun and Snøhvit fields, each producing over 10,000 boepd net, along with the recent Cara discovery. UNITED KINGDOM Baron Oil announced on 27 February that it had agreed with Corfe Energy to farm-in to block 11/24b (Licence P2235). Baron will pay 20% of the costs of the 2018 exploration well on the Wick prospect (currently estimated at £840,000 net), plus £6,500 in back costs in return for earning a 15% interest in the licence (a 1.333 for 1 promote on the well). UK ONSHORE Solo Oil Plc has entered into a definitive sales and purchase agreement for an additional 5% interest in Horse Hill Developments Ltd (HHDL) from Primorus Investments. The deal is an aggregate of cash and shares worth £1 million, bringing Solo Oil’s interest in HHDL to 15% which equates to 9.75% in the Horse Hill licences (PEDL 137 and PEDL 246). NORWAY In February, Suncor announced it had acquired a 17.5% interest in the Norwegian Sea Fenja development from Faroe for a consideration of US$54.5 million. Based on operator VNG’s reserves estimate of 97 mmboe, the deal is valued at US$3.2/boe. Repsol acquired Total’s 7.7% interest in the North Sea Visund oil and gas field in February, thereby increasing its production by 9,600 boepd (based on 2017 output). As a result of the deal, Total will no longer hold an interest in the field. Lime Petroleum has agreed to sell its 20% interest in PL762, to an as yet unnamed buyer, with an effective date of 1 January 2018. The licence lies north of the Skuld field and includes one well, drilled in 1983 which tested the Upper Paleozoic on the Nordland Ridge, but was abandoned as a dry hole.

Figure 2 shows the discovered volumes in South America from 2005 to 2017, split by life-cycle and key unsanctioned projects. By far the best year for exploration in the region was 2010, when almost 16 billion boe were discovered. The Libra and Buzios discoveries in Brazil make up over 50% of the 2010 total discovered volumes. Other large discoveries include the Lula field (2006 and 2009), as well as Junin, Iara, Jupiter, and Orinoco project discoveries (2007 and 2008). Since 2010, there has been a visible reduction in discovered volumes. 2012 was an exception to the trend when Petrobras made the Carcara and Pao de Acucar discoveries in Brazil (now Statoiloperated). We saw some growth in discovered volumes in the region also in 2015. Back then, ExxonMobil made the Liza discovery, adding 1200 million boe in reserves in Guyana. The phase 1 of the project has already been sanctioned and start-up is planned for 2020. Last year, the company added an additional 900 million boe to Liza through the discovery of the Turbot and Snoek fields. Although fewer resources have been found since 2010 compared to historical levels, significant production contributions are expected from the discoveries that have been made in the past twelve years. Figure 3 displays the total spending in South America over the period 20102025. Investments (capex and exploration capex) decreased by 9% last year and are forecasted to stay flat in 2018, growing to over $65 billion by 2025. In Brazil, production start-ups of fields within the Lula and Sapinhoa projects (where a large part of the development cost has already been incurred), as well as corruption allegations and lower oil prices, are the main triggers for decreasing investments in 2016-2018. Spending is estimated to recover from 2019 with Brazil’s Libra, Iara (Atapu North) and Pao de Acucar, Neuquen Basin tight gas developments in Argentina and the Liza discovery in Guyana contributing significantly to this growth. Post 2020, increasing investments are expected in the Statoil-operated Carcara project and the Lula Oeste field in Brazil, as well as the second phase of Junin-6 in Venezuela. Operating costs (opex) are expected to grow to $43 billion by 2020 and increase to $54 billion by 2025.

output is forecasted to continue to decline towards the early 2020s before flattening out at the level of 2.3-2.4 million boe/d. Supply in the remaining South American countries has been rather stable before 2014, with declines observed in Colombia, Argentina and Trinidad and Tobago from 2016 onwards. We currently forecast production in these countries to continue to fall in the future, particularly led by Colombia and Argentina, where fields like Loma de la Lata and Rubiales-Piriri exhibit decline rates of 10-20% per year. 18,000 Discovery (Other)

Ravenspurn South

Helvellyn Helvellyn was discovered in 1985 and was acquired by Alpha in 2001 from BP. The field has been developed by as a single subsea well tied back to the Perenco operated Amethyst A2D platform from where gas is exported to Dimlington. Gas Production began in February 2004, and 19bcf of gas had been produced up to end 2016. There are estimated remaining reserves of c.1bcf. No further development activity is currently contemplated at Helvellyn.

TORS DEVELOPMENT AREA Kilmar was discovered in 1992 and has gas in Carboniferous Namurian sandstones. Alpha acquired 100% equity from BP (2001) and GDF (2004), subsequently selling interests to Sojitz (2005) and Edison (2008). Garrow was discovered in 1991 and has a Rotliegend reservoir. Garrow was an out of

Kilmar is a large structure and the 3 current producing wells do not access all of the calculated gas in place. Detailed reservoir engineering work has identified infill locations and we are evaluating further development options The Garrow NUI platform was installed in July 2008.This is a 3 slot platform, two production wells have been drilled and, up to end of 2016, 7.6 bcf of gas had been produced. Remaining recoverable gas is estimated at 4 bcf.

HELVELLYN Tors The Tors development consists of 2 gas fields, Kilmar in Block 43/22a and Garrow in Blocks 42/25a and 43/21a.

Wenlock The Wenlock gas field was discovered in 1974. Equity in the licence was acquired from BP in 2001 and from ConocoPhillips in 2005. The Wenlock NUI platform was installed in September 2006 with 3 production wells drilled resulting in first gas production in December 2007. Gas is exported via a 37km p i p e l i n e t o t h e Pe r e n c o o p e ra t e d Indefatigable Wenlock has produced 41bcf of gas up to end 2016. There are estimated remaining reserves of 4.5bcf.

Alpha has used the extensive available database to define an optimised, low cost F ield Development Plan that gained technical acceptance from the OGA in December 2015. That plan is based on the development of oil from the Cheviot and satellite Peel fields. There will be a subsequent simple development of the Cheviot gas caps and Padon satellite field. Alpha is developing oil reserves of at least 55 mmbbls and future gas volumes of 120 bcf. Alpha will also look to use the Cheviot facility as a hub for other nearby discoveries and prospects, which have an unrisked potential of some 400 mmboe.

New Broadband 2D Multi-Client Seismic

Legend Spectrum Mozambique proposal: 19,000 km, 10x10 km grid License blocks

in association with

Spectrum is undertaking a comprehensive long-offset Broadband 2D Multi-Client seismic survey offshore Mozambique. The survey comprises a variable grid totalling approximately 19,000 km. This new seismic data will image the subsurface potential in open areas of the southern Rovuma Basin and the western flanks of the Kerimbas Graben, west of the Davie Fracture Zone, revealing the prospectivity in this region for the first time. New 2D data will play a key role in refining our understanding of the hydrocarbon potential of the area and accelerate exploration activity in what is believed to be an oil-dominated region offshore Mozambique. Survey acquisition is due for completion in Q2 2018 with final products available in Q4 2018. +44 1483 730201 PESGB April 2018 63
