Special interest community launched for geochemistry

Boiling mudpots in the geothermal area Hverir, Myvatn region, northern Iceland.

EAGE prides itself on being a uniquely multi-disciplinary professional network, and it is always growing. This is why we are excited to be launching a new special interest community on Geochemistry, in collaboration with EAG (the European Association of Geochemists). Geochemistry is a key topic featured in many EAGE and EAG events, including Goldschmidt meetings, the EAGE Annual and the recent GET conference. It is therefore no surprise that this group has been in the works for some time, but you will notice it is also the pilot for the first joint community with an associated society. We are happy to join forces on this project with EAG, a globally recog-

nized non-profit organization promoting excellence and knowledge exchange in geochemistry, and an associated society of EAGE since 2017. This collaborative initiative will bring our cooperation with EAG one step further in facilitating connections between industry and academia, and exploring new opportunities in all areas of organic and inorganic geochemistry. What can members of each society (or both) expect? A network dedicated not only to those whose main focus is geochemistry, but also for everyone interested in geochemical applications that may contribute to their work. We especially invite you to join if you’d like to explore new opportunities in FIRST

the field or if you are considering pursuing a career in geochemistry. Just like our other special interest groups, the community will have a space on LinkedIn to connect, share news and ideas, participate in discussions, career development activities, etc. In addition, we will make sure to share opportunities offered by both societies to present or publish your work, tools to support your career progression and learning resources.

NO MORE SEPARATION ANXIETY

DUG DEBLEND

Blended surveys provide a number of operational and technical advantages. In the OBN example pictured above, three triplesource vessels were firing within 15 km of each other. Such overlapping shots must first be separated to permit subsequent processing. DUG Deblend is our inversion-based solution which can reconstruct shots as if they had been acquired separately. It generalises to a wide range of scenarios and can also simultaneously deblend seismic interference, which is simply an unintended form of blended acquisition. With DUG Deblend, there is no more separation anxiety. (Data courtesy of AGS and TGS)

EAGE near surface sessions featured at North American events

Mount Assiniboine in Banff National Park, Alberta, Canada.

The tradition of our professional societies exchanging some of the best presentations from their major events lives on. In March, eight papers previously presented at EAGE’s Near Surface Geoscience were presented in North America at the near surface SAGEEP 2021 annual conference and at the KEGS Symposium of the Canadian Exploration Geophysical Society. Over the years our Near Surface Conference series have been able to attract participants and papers from a wide variety of countries, disciplines and institutions. Selecting some of the highy rated presentations to form ‘Best of’ sessions has provided a great currency to exchange with other societies. The cooperation helps provide a wider platform for excellent research, and also strengthens ties in the professional community. The SAGEEP conference is home to the longest running ‘Best of’ exchange programme. One of the presenters this year was George Apostolopoulos from the National Technical University of Athens and former chairperson of the Near Surface Geoscience Division. ‘My contribution to the session focuses on geoarcheology, a topic well established in Europe. Subsurface research on anthropogenic activities is of great interest outside of Europe as well, so it’s great to connect to my peers outside ’ Myrto Papadopoulou (Politecnico di Milano) relates her SAGEEP expe8

rience: ‘The presentations included in these sessions are a sample of the innovative research and technological achievements advancing in Europe in the field of near-surface geophysics, while topics such as mineral exploration, can be highly interesting for the North American community’. Janaa Gustavson (Guideline Geo) was one of the presenters selected to also present her work at the KEGS Symposium. ‘My work focuses on the benefits of using modern non-destructive geophysical techniques compared to more traditional ways of investigation. Sound knowledge of efficient geophysical investigation techniques transcend borders, after all, so

it’s good to connect to like-minded people in Canada on this.’ Magdalena Markovic Juhlin (Uppsala University) agrees. ‘My contribution focused on reflection seismic methods for mineral exploration. Canada is well known for its advances in mineral exploration, so I’m hoping to get good questions and comments about my work. Having this platform with European and North American researchers can only benefit the development of new approaches in methodology and technology.’ The eight EAGE ‘Best Of’ presentations can all be accessed through EarthDoc as part of the Near Surface Geoscience proceedings.

How GET21 presents energy transition challenge to future of geoscience and engineering community

SERIES

PREVIEW

Welcome to our new First Take event preview series. This is where we go behind the scenes to talk to organizers about their goals for upcoming EAGE meetings and what participants can expect. Here we feature the upcoming GET21 (Geoscience and Engineering for the Energy Transition) conference due to be held in Strasbourg on 23-25 November as a hybrid event (in person and virtual). We spoke to Esther Bloem (Norwegian Institute of Bioeconomy Research – NIBIO), Karin de Borst (Shell) and Giovanni Sosio (Schlumberger).

Esther Bloem

How did the idea of the GET conference series come about?

Karin de Borst

de Borst: Energy transition has been on EAGE’s agenda for quite some time. The idea emerged to organize an event that would span across the Near Surface Geoscience and Oil and Gas divisions, and one that would address all subsurface components that have a relevance to energy transition and require input from geoscientists and engineers. Bloem: We see the Near Surface community growing and introducing new topics at conferences. So there is a lot of discussion going on around energy transition. In addition, society is asking for new energy sources. The EAGE is listening, and so is the professional community working in this field.

What did you learn from organizing the first GET in 2020?

Giovanni Sosio

de Borst: It may sound simple, but it’s particularly important to reserve enough time for discussion and participant interaction. It was especially challenging for GET 2020 in a virtual setting. I was quite impressed by the level of engagement of the delegates and the very active discussions that we had during the technical sessions. In the closing sessions,

delegates came together with the co-chairs and session chairs with highlights of the programme during the day. This is an element we intend to promote for GET2021.

Which topics were of most interest? And will there be any changes? Sosio: The one that drew the largest audience was the plenary session on Solutions and Society. It was so successful that we’ve agreed to keep it this year. In order to add to these non-technical type of topics, we’ve decided to include a session on environmental sustainability. Bloem: We hope to really engage participants in the society discussion, to see what this means for energy transition, what kind of impact it has on our ecosystem services, and the implications for the value chain related to near surface energy resources.

What are the specific changes being made to the scope of the conference? de Borst: As well as more on environment and sustainability, we are expanding the scope of the more technically focused programme,


EAGE NEWS

for example, with an offshore wind energy theme. Last time we focused on the more classical subsurface uses in the energy transition, such as geothermal, CO2 storage and energy storage. But it was always the intention to arrive at some point at a platform that would address all different subsurface uses. Wind energy seemed like an obvious choice, because you have quite some common topics with the more classical and deeper subsurface fields, be it related to subsurface characterization, monitoring, data interpretation, data integration, or data analytics. We hope that this gives a setting that will result in interaction between participants coming with a background in one of the fields. With luck, we will see some integration and cross fertilization arising from this initiative.

There are a lot of different topics that have to be put together to achieve some measure of integration. So how realistic is this goal? Bloem: Well, what we see is that there are different approaches being taken, and lots of new initiatives ongoing. There are actually a lot of opportunities to optimize energy demands and availability and at the same time to reduce waste products. But to what extent it will really be integrated is difficult to predict. de Borst: We will start on a small scale, zooming in on the technical challenge of integrating different subsurface uses. This would be in response to having many claims to a limited resource like the subsurface and also hoping to get benefits from the combined use of the subsurface from an economic point of view. For example, we can integrate CO2 storage and thermal energy production in the context of CO2 plume geothermal. There are also ‘dual play’ opportunities with regard to integrating elements of new energies into conventional oil and gas facilities. We hope to see a lot of contributions, plenty of ideas being presented and shared, as well as finding out how knowledge, workflows and metadata can be transferred across different subsurface applications and disciplines.

Does the choice of Strasbourg, home of the European Parliament, mean a European focus for the meeting. de Borst: We want to take the opportunity that we are very close to many European institutions. It may help to attract European officials to the conference, so that we can also have a discussion around legislative issues, policy issues, and also to share information about funding opportunities. We hope for integration in a different context, namely integration between technical experts and officials. Collaboration is key to make impactful changes. Sosio: Strasbourg also has another significance. The area around Strasbourg has an association with the French petroleum industry. It is where the first wireline log was acquired nearly 100 years ago. Now one century later today, both the German and

French sides of the Rhine are becoming a centre of the European drive to transition to geothermal energy. So the technologies that were used for petroleum exploration are now being applied to the development of geothermal energy.

What about energy poverty, and the challenge of bringing transition to developing countries? Is that included in the programme? de Borst: We definitely want to address this and have included equitable energy transition in our Society and Solutions theme. Because this is a technical programme, our call for abstracts may not give the topic enough traction. But we will try to stimulate discussion and awareness through keynote speeches and panel sessions. This should generate a conversation around the technical and financial challenges and potentially how we best can transfer technologies or skills to developing countries to help them to be successful on their decarbonization journey. Bloem: There are great opportunities here, because alternative energy sources offer more power generation options, so you’re not depending on just one single source. You can really look into what is the best solution for different regions, for example, some countries might not have such a good national grid and alternative sources may provide an option to solve this.

The really big question is how much of an opportunity does energy transition promise for geoscientists and engineers going forward? de Borst: It is probably difficult to put it in quantitative terms, but this is definitely an opportunity. The subsurface will play a key role in energy transition, for energy production and energy storage, and you also need a lot of minerals that come from the subsurface for batteries, and potentially for increased nuclear power. For the subsurface, we will always need geoscience and engineering skills to image the earth’s structure, but also to make sure that we operate in a safe and sustainable way. Sosio: We need to adapt our skills to these new and different uses of the subsurface. In our call for abstracts, we are pushing the authors not to shy away from discussing which skills are relevant to embrace energy transition, and how much of a change there will be? This was a topic that in 2020 was perhaps a bit overlooked given the technical focus of the conference.

So for the EAGE as a professional society, how do you see the significance of the event? de Borst: It is very important that the Association embraces changes in the role of the members as they are encountering the energy transition and to offer events, information and training that address this changing professional working environment.

International audience for LC Aberdeen near surface geoscience workshop Local chapter committee members Anna Fulop and Simona Caruso report on a successful near surface geoscience online workshop organized by the EAGE Local Chapter Aberdeen on 2 February 2021.

Fictional island of Windia (photo courtesy of RockWave and Minecraft).

Following the format of the 4D workshop organized by the LC Aberdeen in January 2018, the idea for the workshop evolved over the last couple of years, initially as an offshoot of the EAGE’s Near Surface Geoscience/Shallow Marine conference. However, with the travel restrictions imposed on all of us over the past several months, it was decided to host this as a free online event instead. To everyone’s surprise - and delight - the workshop registration, capped at 200 delegates, was oversubscribed a few days ahead of the event, and attracted a global interest (something an in-person workshop could not have allowed). The workshop opened with a brief introduction of the LC Aberdeen’s activities by our chair, Paul Mitchell, and was followed by five captivating and complementary talks related to shallow geoscientific data for marine engineering projects, delivered by a range of UK-based industry experts.

The first talk on ‘UHR3D Seismic Data for Sub-seabed Boulder Detection’ presented by Scott Griffiths (Fugro) showed how, in the context of the glacially influenced Pleistocene deposits in NW Europe, an ultra-high resolution 3D seismic solution can be used to resolve buried boulders, thus constraining one of the main hazards likely to be encountered during the planning, design and installation of seabed infrastructure, such as fixed offshore wind turbines. The talk illustrated examples of semi-automated mapping tools resulting in more informative distribution maps. Next, Peter Cox (RockWave) took us on a journey to the fictional island of Windia and demonstrated the hidden potential of advanced and bespoke marine seismic data re-processing and ‘repurposing’, in his talk on ‘Improved Certainty in Ground-Modelling with Optimized Seismic Processing’. He showed how the near-surface information contained in both oil and gas

exploration data and UHR seismic data, in particular mixed-phase sparker data, can be retrieved and exploited through optimized processing flows to support and refine ground models. The third talk was jointly presented by Simona Caruso and Lewis Cottee (Vysus Group) on ‘Extended Top-hole and Foundation Zone Interpretation Techniques’. As oil and gas exploration and offshore wind developments move into ever more complex environments, with increasing foundation challenges, our presenters highlighted the importance of comprehensive desktop studies and the need to appreciate data limitations as the way forward to understand localized variations and bring regional context to the results. Through case studies they presented some of the ways advanced techniques, such as seismic attribute analysis, seismic geomorphology, seismic inversion and semi-automated mapping can be used to improve the detection of shallow geohazards and overall interpretation reliability of marine near surface data, ultimately offering some insight or input to quantitative models. Robert Mullen (RPS) delivered the penultimate talk on ‘Collaborative VSP Acquisition to Optimise Velocity Control and High Resolution Imaging’. He described the many challenges faced during a unique collaboration project for DTEK Oil and Gas in Ukraine, and how this approach provided high resolution imaging of the top carbonate structure, velocity control and assisted calibration of quantitative interpretation using the Amplitude Variation with Offset (AVO) response. The talk highlighted how an accurate velocity model from surface was key to generating the high-resolution images which informed the structural model. The acquisition of Vp/Vs veloc-

Bill Barry, Mullen’s former colleague and main man in the field on this project, took part in the questions. Mark Finch (Ternan Energy) returned to the challenges of offshore wind development with the final presentation of the day entitled ‘It is what it is: managing

ground risk in offshore wind’. Drawing from his more than 30 years’ experience working in marine geotechnical engineering and more specifically his 15 years in offshore wind, Finch discussed ground conditions uncertainty and seabed risk management.

Our special thanks to the EAGE, and to Francis Buckley and Kinga Wróblewska for initiating this workshop and helping us move it forward, and to the rest of the LC Aberdeen committee for its support in making this event a success.

Looking forward to the 23rd edition of Geomodel Anticipation is growing for EAGE’s 23rd Scientific and Practical Conference on Geological Exploration and Development of Oil and Gas Fields (Geomodel 2021) due to be held on 6-10 September in Gelendzhik, Russia. Geomodel 2020 was held in a difficult environment, but we became one of the first events to successfully meet in real and virtual space. Over the course of the year we have become more technically competent and we are not afraid of the opportunity to take part in conferences from our office or home. The conference format allows you to choose the form of participation: you can come to the conference and participate in all events in person, or connect to the conference remotely. In any case, we look forward to your participation and hope that your presentations, questions and participation in discussions will influence the collective

work of everyone who wants to improve the level of knowledge and achievements. We like to think that Geomodel conferences differ from others as they offer more opportunities for professional communication and growth to everyone, regardless of experience and direction of work. The organizing committee, chaired by Alexey Shevchenko (PetroTrace) and Alexander Mityukov (RN Exploration), and EAGE will try their best to make your participation in the conference as rewarding as possible. Abstract submission is open until 20 May 2021. In addition to traditional topics, such as general geology and regional sessions, geophysical research, processing and interpretation of geological and geophysical data, field geophysics and petrophysics, exploration, geomechanics, AI and machine learning, and unconventional resources, this year we are inviting

discussion on new and hot challenges for the geoscientists such as the technologies of remote work, digitalization of data processing in oil companies and government departments in the field of subsoil use, and decarbonization in the oil industry. Registration with discounted registration fees is available until 15 June 2021, so be sure to book your spot.

Plenary sessions at Geomodel have always been provocative and inspiring.

Berlin students reflect on chapter life during pandemic

Field trips are a welcome diversion.

EAGE Student Chapter Berlin from the Freie Universität Berlin consists of a multi-disciplinary group of undergraduate and postgraduate students. Having such a diverse cast of members helps us network and find common ground when working on an international scale with other student chapters. For example, a great event, despite the pandemic, was the field camp we organized and ran with Uppsala University in Sweden focused on ‘Mitigating landslide hazards: Characterization of quick clay deposits along Göta River, Sweden’.

More fun ...

Like many other chapters in the world, we are also limited in our possibilities due to the Covid-19 pandemic. But we realized it is important to have regular meetings and plan projects for the future. A reframing of the situation was necessary and so we see the current state as an opportunity to try out new ideas. We hope to take part in the online GeoQuiz again, as we do every year as well as host regular meetings where students can present their current Bachelor or Masters theses followed by a discussion. We want to give everyone the opportunity to improve their presentation skills and to discuss scientific topics. To compensate for the lack of large projects, we will opt for one-day excursions that can be planned flexibly, such as to the German repository for low- to medium-level radioactive waste in the Konrad mine or the open-pit lignite mine of MIBRAG south of Leipzig. Here, we

will consider not just the purely geoscientific aspect but also the immense significance to society. As we had an incredible and enriching experience last year through our field camp, we plan to pass on this concept to our future chapter members. We are currently in talks with the EAGE Student Chapter at the University of Rio de Janeiro for a joint field camp in Brazil in Summer 2022. The idea here is to try out and learn about the very environment-friendly exploration method deploying magnetotellurics in the field. Every year in December there is a geophysics Christmas party at our university, which is co-organized by our student chapter. Last year it had to be

canceled but we hope that it can take place again this year and that we can all talk about our experiences together. We continue to network and work on projects. Unfortunately, this also must take place online, but this does not detract from our meetings in the meantime and we still have a lot of fun.

The EAGE Student Fund supports student activities that help students bridge the gap between university and professional environments. This is only possible with the support from the EAGE community.

PERSONAL RECORD INTERVIEW

Nina Hernandez

Personal Record Interview

From under the volcano to high tech business and contemplating Mars Five years ago Nina Hernandez founded Kuala Lumpur-based Iraya Energies. The company harnesses AI techniques to extract extra value from unstructured document databases stored in oil and gas and energy sector companies. Hernandez has degrees in chemical engineering and petroleum engineering from the University of Philippines and Technical University of Denmark. In this first article in our new Personal Record interview series, she provides a glimpse into the life and times of a start-up entrepreneur.

Tell us a little about your background and how you got into geoscience? I was born in a small village at a foot of a volcano and as a child used to watch the lava flow from our window. My first summer job as a student engineer was to repair corroding water pipes in a geothermal field close by. I thought it was very cool to wear a steel toe and be with nature at the same time, so I fell in love with the idea of measuring the earth as a profession.

for several years, which enabled us to develop the technology very fast, and we are deeply proud about that. Fast forward, Microsoft became a partner and Petronas in Malaysia came in as an institutional investor, and that changed many things for us. We were able to scale our infrastructures and professionalize our support functions so we can serve our customers better.

How did the idea for your company arise? It was during the oil crisis of 2016 (we seem to have a lot these days). There was another round of reorganization in Schlumberger where I worked for almost 13 years, and I had to leave. The new-found time gave me an opportunity to study the latest trends in digital technology such as Netflix, Spotify, and understand how we could use those human-tech interaction principles in a very traditional industry such as oil and gas.

You are working with EAGE on EarthDoc. What would be the benefit to members? ED2K is our very ambitious, and future-forward collaboration with EAGE. All of EarthDoc’s 70,000 articles are geotagged to 800+ basins. Natural language processing, auto-image recognition, and recommender systems are fully built-in into the ED2K system. The goal is to use decades of O&G subsurface knowledge to provide answers to some of the most pressing questions of our generation: energy sustainability, transition, and climate change. The benefits – now we can read the Earth better, and hopefully support the net zero agenda by 2050.

What were the main challenges in starting and financing your own company? When we started in Singapore, it was already a very hip and happening place for B2C tech start-ups. However, there was a limited support system for a B2B energy deep tech like us. So Iraya bootstrapped

Your moonshot moment? Perseverance, Nasa’s fifth rover and geologist landed on Mars on 18 February this year to seek signs of ancient life. In Iraya part of our work is using neural network techniques to detect fossils and understand biomarkers. My ‘Mars-shot’ moment is for Iraya’s technology to support space FIRST

exploration by doing what we do best – reading the earth. Where do you see yourself in 10 years time? I hope to see myself to be in a position where I can mentor young tech movers and be an angel investor myself, or maybe in government policymaking. I believe that the world is changing a lot these days; there are many great, benevolent tech ideas from our young people for an equitable world. We need to enable them because they will be the ones to inherit the planet that we will leave behind. What would be your advice to young entrepreneurs? Gain experience, do a job, work for a boss. From a practical perspective, not everyone can drop out of college and be Mark Zuckerberg, as we often have family and financial responsibilities that have to be balanced with entrepreneurship. Before founding Iraya, I learnt many things in my normal job – how to manage priorities, deal with people, sales, technique. Invest in your training and in yourself. How do you spend your free time? As much as possible I try to do long walks in my free time, and listen to music. Ensuring that we take care of our physical and mental health is one of the best gifts that we can give to ourselves and families in this time. BREAK

PGS and Shearwater sign long-term framework agreements with Equinor for 4D surveys

Amazon Conquerer is among the vessels expected to be deployed.

Equinor has awarded PGS and Shearwater GeoServices framework agreements for a range of seismic services in a move that is expected to be copied throughout the industry. The agreements, which have an estimated value of around $83 million, will cover 4D towed-streamer seismic acquisition on the Norwegian Continental Shelf (NCS) for an initial two years. ‘This is a new way of working with seismic suppliers. We are moving away from annual tenders towards a more long-term collaboration model. This will ensure improved predictability and more sustainable rates for suppliers in the seismic industry that is traditionally exposed to significant cyclicity,’ said Peggy Krantz-Underland, Equinor’s chief procurement officer. The two-year agreements — which will give the heavily leveraged seismic contractors important visibility of future earnings

in what is predicted to be a continuing uncertain market — include additional two two-year options and can also be applied for the UK continental shelf. ‘4D seismic gives us better data to map remaining oil and gas resources as the reservoirs are being produced. These contracts will help us to optimize the reservoir drainage and place new wells, and thereby achieve our ambition of recovering 60% of oil and 85% of gas on the NCS,’ said Charlotte Bøe Tjølsen, vice-president of petroleum technology operations in Equinor. As part of the agreement, PGS is scheduled to acquire two 4D GeoStreamer monitoring surveys in 2021 over Fram and Tordis/Vigdis fields. The first survey is scheduled to start in June 2021, and the total duration for the two 2021 projects is estimated at around two and a half months. PGS has also been awarded a specific framework agreement for 4D seismic services at the Gullfaks field in the Norwegian FIRST

North Sea. The agreement comprises an exclusive right to acquire up to three surveys prior to 2031. Rune Olav Pedersen, president and CEO of PGS, said: ‘We operate in a cyclical industry with low visibility, and longer-term contracts improve our order book and financial predictability in a challenging seismic market. An important part of our strategy is to maintain leadership in the production 4D segment. ‘The confidence Equinor shows by awarding us these frame agreements confirms our strong position in the 4D market, the reliability of our Ramform vessels and the data quality provided by our GeoStreamer technology.’ Shearwater has been awarded an initial survey over the Heidrun Field in the Norwegian North Sea. It will allocate one of its Isometrix vessels for the one-month survey, which is expected to start in Q2. ‘Shearwater’s established leading 4D technology positions us well to deliver high-quality time-lapse measurements for Equinor. This new framework agreement provides us with increased visibility and the opportunity to optimize utilization and efficiency into the future,’ said Irene Waage Basili, CEO of Shearwater. Equinor said: ‘PGS and Shearwater are Norwegian seismic suppliers with strong technical solutions, modern and well-equipped vessels and a good track record for Equinor.’ BREAK

Rystad predicts surge in deepwater offshore projects in next five years Offshore project commitments are expected to reach a new record of almost 600 projects in the period to 2025, according to new research from Rystad Energy that will be music to the ears of struggling seismic and oilfield contractors. Deepwater commitments will enjoy the largest growth as their cost has now become much more competitive against greenfield continental shelf reserves.

more economically viable after day rates for drilling rigs and offshore supply vessels fell in the wake of the oil price crash in 2014 and 2015. This offers significant support for companies interested in deepwater,’ said Rajiv Chandrasekhar, energy service analyst at Rystad Energy.

Total offshore project commitments (25% of overall capex awarded through contracts) declined in the period 20162020 to 355 projects, from 478 in 20112015. From the beginning of 2021 to the end of 2025, Rystad has forecasted 592 commitments, with growth across all water depth levels. Although shallow water commitments will take the largest share of the total offshore project pie, rising to 356 from just 206 in the last five years, the increase is more modest, about 10%, compared to the 2011-2015 count of 323 projects. The most impressive growth is that of deepwater commitments with the number of projects rising to 181 from 106 in 2016-2020 and 115 in the five years before that, said Rystad. Ultra-deepwater commitments will also tick up but not by similar margins, as costs still bite. Rystad is expecting about 55 projects from this year until 2025, up from 43 in the previous five years. ‘The search for large new fields in deep and remote waters became much

reserves compared to deepwater has fallen dramatically from the highs seen in 2014 – from more than $5 per barrel of oil equivalent to only around $1/boe in 2020. In terms of greenfield expenditure, Rystad expects offshore project commitments in 2021-25 to be worth more than $480 billion, eclipsing the 2016-20 tally of around $320 billion by 50%. However, this is still well below $673 billion worth of commitments made in 2011-15. ‘We expect ultra-deepwater activity to be primarily concentrated in South America, with over 50% of the total committed value, while the Middle East is likely to lead shelf developments with 40% of the total value,’ said Rystad. ‘Deepwater investments are forecast to be less dependent on any particular region, with a quarter of greenfield expenditure expected in Europe.’ Meanwhile, Rystad research has shown that the number of offshore wildcat wells will rise over the next two years despite the fact that in 2020 the success

rate of wildcat wells plummeted to an alltime-low of 10.6%, marking an annual decline for a fourth year in a row. During the first half of the last decade, operators enjoyed high success rates in their wildcat drilling campaigns, of 40-60% for onshore and 30-40% for offshore. The 2020 score ended at 24.8%, down from 28.6% in 2019 but slightly higher than the 24.1% score recorded in 2018. ‘The lack of availability of easily exploitable prospects, combined with dying exploration activity in once rich onshore areas such as the Middle East, has led to the decline in the onshore success ratio. Most of the easily mappable structural prospects with shallow reservoirs have already been thoroughly explored, leaving wildcatters to struggle primarily with technically challenging prospects,’ said Palzor Shenga, vice-president at Rystad Energy’s upstream team. Rystad Energy said that it does not foresee a significant improvement in the onshore success ratio soon and much more activity will be focused on offshore areas. ‘Deep and ultra-deepwater areas have delivered decent success over the past couple of years,’ it said. Although new volumes found in 2020 exceeded 10 billion barrels, only 12% of the wildcats had a volume potential greater than 250 million barrels of oil equivalent (boe). Of these, 66% targeted reservoirs in deep and ultra-deep waters, 20% were in onshore basins and the remaining 14% were in shallow waters, said Rystad. ‘In 2021, Rystad expects around 70% of the high-impact wildcats to target deepwater and ultra-deepwater plays, while 17% will be in offshore shelf areas and the remaining 13% onshore. From about 474 onshore wildcats in 2020, Rystad Energy projects the number to fall to 253 in 2021 and rise slightly to 270 in 2022, never exceeding 300 wells per year through to 2025. The number of offshore wildcats, however, is forecast to increase to 217 in 2021 and 300 in 2022, from about 180 last year.

PGS releases final data offshore Malaysia

Final data is now available for the entire Sabah area, including the phase 5 sector (marked in orange).

PGS has released final imaging products on all parts of the giant Sabah multi-client project, enabling AVO analysis of prospects and leads within the entire offshore Sabah Basin.

Phase 5 covers the inboard trend of the Sabah basin, providing imaging of Miocene-Pliocene turbidite complexes where reservoirs are trapped in the complex fold and thrust structures, as well as stratigraphic settings. This structural trend has produced many discoveries. Tad Choi, PGS sales and new ventures manager for Asia said of the survey covering several of the blocks on offer in the recently announced 2021 Malaysian Bidding Round (MBR): ‘The new, fully AVO-compliant dataset for Phase 5 will improve understanding of the complex geology across the Sabah Trough and the Fold and Thrust Belt terranes, enabling advanced QI workflows to derisk reservoir presence and variability.’ FIRST

Phase 5 was acquired by PGS in 2020 and brings the total coverage to 47,000 km2. PGS said the Sabah project would continue to expand on the expectation of new licensing opportunities offshore Malaysia. The consortium partners are planning further shallow-water acquisition inboard in 2021. Meanwhile, PGS said that it is experiencing an increase of seismic acquisition project activity. Based on project awards so far, PGS has started preparations to reactivate Ramform Vanguard for the summer season, with acquisition expected to commence in April. In addition, PGS will activate Sanco Swift to be used as a source vessel for at least three months on awarded projects. BREAK

Norway launches streamlined digital platform for reporting seismic surveys The Norwegian Petroleum Directorate has launched a digital platform for reporting geophysical surveys. The new system will streamline reporting of geophysical surveys and ensure that all players in the fisheries and the oil industry have a complete overview of data acquisition, both planned and current, as well as which companies are involved. Users can follow case processing in real-time. New and enhanced mapping technology has made it easier to visualize reported

plans and to give good ‘snapshots’ of the activity, said the NPD. At the same time, the system provides an overview of fisheries and spawning fields, making it easier for companies planning geophysical data acquisition to schedule their surveys in a way that can be adapted to the fishing industry. The NPD said its existing digital solution for companies to report their plans for collecting geophysical data on the Norwegian was a ‘cumbersome system which did not accommodate newer digital technology’. All parties with permits for acquiring geophysical data on the Norwegian Shelf must report their plans to the authorities at least five weeks before they plan to start the activity. The companies must report when they plan to collect data, in which area, what type of survey (for example, seismic or electromagnetic surveys), and also specify what type of equipment they will use. Changes are often reported in the plans once they are under way.

Alongside the Norwegian Petroleum Directorate (NPD), both the Directorate of Fisheries (Fdir) and the Institute of Marine Research (HI) are consultation bodies in the work on geophysical surveys. ‘We process around 500 reports and change reports every year. Since these reports have been processed manually until now, this has been time-consuming work with numerous letters, phone calls and a lot of emails back and forth across the agencies,’ said NPD director technology and coexistence, Torgeir Stordal. Seismic contracting and data companies were consulted prior to development of the system and certain requirements were established for functional solutions based on user input, said the NPD. The reporting system is the first interactive solution developed for external users on the NPD’s new IT platform, and Library of the Norwegian Continental Shelf. The information can be found on npd. no. Users can log in securely via altinn.no

CGG to shoot new survey in the Northern North Sea CGG has announced phase two of its multi-client 3D survey in the Northern North Sea that will add a second azimuth over CGG’s existing Northern Viking Graben (NVG) multi-client 3D survey and extend coverage into the UKCS. Starting in early May and continuing throughout the North Sea season, the 2021 phase two acquisition will add approx. 8000 km2 of new data in an E-W direction. Similar to the 2020 phase one, multi-component technology will be used for the acquisition, and this new data will be processed together with the existing N-S data, using CGG’s latest velocity modelling and imaging technology, to produce a dual-azimuth volume. As already confirmed by initial results from the 2020 phase one acquisition, the added azimuth will enable CGG’s proprietary processing to address

and improve the imaging of the multi-directional fault patterns prevalent in the region. Improved resolution will help to resolve complex and marginal reservoir stratigraphy. Fast-track data from the phase two acquisition are expected to be available by the end of 2021, and final processed data during the second half of 2022. Sophie Zurquiyah, CEO, CGG, said: ‘With phase two of our planned multi-year project, CGG continues to follow its strategic path of expanding and enhancing its data library in mature and prolific hydrocarbon regions. This expansion draws on CGG’s extensive understanding of the Northern Viking Graben and builds on our 44,000 km2 of existing coverage in the Northern North Sea. The new data will further de-risk existing fields and unlock the significant remaining near-field potential.’

3D at Depth moves into geophysical surveys

Shearwater wins contracts offshore Norway, Australia and Angola

3D at Depth will provide surveys for offshore wind farms.

3D at Depth has launched an offshore Geophysical Survey Services division. The division will provide surveys in the areas of offshore wind farms, pipeline routes, environmental site surveys, offshore hydrocarbon projects, and civil engineering. The Geophysical Survey Service division is supported by a team of 3D data specialists, geophysical and hydrographic professionals providing a multi-disciplined approach to guide, identify and analyse data acquisition initiatives across survey campaigns, said 3D at Depth. The Geophysical Survey Services division will leverage 3D at Depth’s in-house electronics, system integration, and design capabilities as key differentiators. The company’s patented Subsea LiDAR (SL) 3D laser data sets will be merged with multibeam echosounder (MBES) multi-frequency, multi-spectral data acquisition and optical technologies to enable more robust, higher-quality output, said 3D at Depth. Deepwater offshore, inshore, and nearshore projects will use 3D at Depth’s integrated autonomous or tethered underwater vehicle and vessel-mounted survey solution. The fully integrated solution incorporates a hovering supervised autonomous AUV/ROV package and takes advantage of 3D at Depth’s Subsea LiDAR (SL) laser with remote sensing technology – inertial navigation coupled with a multibeam echosound-

er and pipeline and hydrocarbon leak detection sensors. ‘Since the company formation, we’ve focused on developing flexible site and subsea asset characterization technologies designed to reduce crew time and dramatically lower CO2 emissions, while increasing the speed and quality of the results,’ said Neil Manning, COO of 3D at Depth. ‘By deploying smaller, more efficient vessels that can be operated safely outside the 500 m zone or offshore exclusion areas without sacrificing data quality is a differentiator. When we looked at the problem, we found a gap in the geophysical market for this type of implementation that delivers cost-efficient surveys that still provide maximum data quality. Specifically, we have used a solution from our deep-water technology portfolio to meet the current requirements of the shallow-water survey market. 3D at Depth recently completed a big project for post-hurricane NTL surveys in the Gulf of Mexico for a large US-based pipeline company. The project continues with expanded requirements. ‘Geophysical and geotechnical capabilities for the projects will be available from vessel-mounted or subsea vehicle-mounted methods to allow for both long and close-range inspections which enable a blend of efficient data collection and high data quality to meet and exceed the demands from the end-users,’ said 3D at Depth.

Shearwater has won a contract or an ocean bottom seismic (OBS) 4D survey from Aker BP at the Ivar Aasen field in the Norwegian North Sea. The survey will commence in Q2 2021 and will employ Shearwater’s multi-purpose vessels the SW Cook and SW Tasman, using proprietary technology. The project duration is approx. 1 month. Meanwhile, Shearwater has won a contract for a 3D multi-sensor marine seismic survey in the Otway Basin, offshore Australia. The two-month survey is expected to start in Q3 2021 covering an estimated 2700 km2, employing the vessel Geo Coral using a multisensor streamer system with a variable streamer spacing configuration. ‘We see a solid, consistent level of activity in Australia where we have multiple projects booked in 2021, said Basili. ‘We observe increasing regional demand for our vessels equipped with high-end technology, which is reflected in backlog and utilization.’ Finally, Shearwater has won a contract for a 4D monitor marine seismic acquisition survey in Angola from Total. ‘We have seen a notable increase in interest for 4D technology for our clients’ planned projects in 2021, which is demonstrated by the award of this project in West Africa’, said Irene Waage Basili, CEO of Shearwater. The survey comprises a twomonth project on the GJDR Development area of Block 17 commencing in Q1 2021. One of Shearwater’s multi-sensor equipped vessels will be used for the survey in conjunction with source vessels from the Shearwater fleet.

TGS prepares for offshore wind revolution

An offshore windfarm under construction off the English coast at sunset.

TGS has predicted that 2021 will be a bumper year for the offshore wind industry as the company prepares to devote more of its geoscience resources to the sector. ‘Already this year there have been a number of eye-catching announcements that indicate a positive direction of travel for the sector and bodes well for considerable growth in the near-term and the years beyond,’ the company said. ‘One of the industries that are best placed to take advantage of offshore wind’s growth is the oil and gas industry, with its unique history of decades of

shallow and deepwater field development. From fabricators and seismic operators to construction specialists and shippers, a large number of oil and gas companies are swiftly making the transition over to the offshore wind market due to the alignment of the skills required for both industries.’ TGS pointed to the auction of seabed plots for offshore windfarms off the coasts of England and Wales and two windfarm sites in the Irish Sea that are attracting bids of some $200 million each. Meanwhile, the Danish government confirmed that it had taken a majority stake in a £25 billion artificial ‘energy

island,’ due to be built 80 km offshore, in the middle of the North Sea. The energy hub will be the largest construction project in Danish history. Alongside an additional wind hub on the Baltic island of Bornholm, the two hubs will initially support 5GW of wind generation and triple Denmark’s installed offshore wind to as much as 12GW. Finally, Shell has signed an agreement with Irish marine renewables developer, Simply Blue Energy to acquire a 51% share in a floating wind farm to be built in the vicinity of the Kinsale gas fields off the southern Irish coast, which are being decommissioned. As floating wind technology can be installed in deep waters, it will allow the Emerald Project to be sited between 35 km and 60 km offshore, while reducing any visual impact, said TGS. ‘These and other recent heavyweight announcements prove that Europe is now a clear leading force in offshore wind and other green technologies that power the energy transition.’ TGS said. In 2020, the European Commission laid out its Green Deal to achieve carbon neutrality by 2050. As part of this goal, it stated a need to increase offshore wind capacity to 300GW for the continent’s targeted carbon reductions to be met. The EU has highlighted its €672.5bn ($800 million) Recovery and Resilience Facility, of which it has earmarked a minimum of 37% towards green transition, said TGS.

DMT shoots 2D survey for geothermal project in Germany DMT is carrying out a 2D survey to analyse the potential of geothermal energy in Hagen, Germany. Two seismic profile lines, each 11 km long, have been measured in the urban areas of Hagen, Dortmund, Herdecke and Schwerte on behalf of Kabel Premium Pulp & Paper from Hagen, together with the Fraunhofer Institute for Energy Infrastructure and Geothermal Energy IEG. The aim is to find out whether the location in Hagen is suitable for using geothermal energy at a depth of 4000 m both technically and economically. Kabel Premium has set itself the goal of covering large parts of its process steam generation – currently around 500,000

MWh annually on the basis of natural gas – with renewable energies. The first profile line runs from the northeast to the southwest, for the most part on the A1 motorway (Schwerte driveway to the Eichenkamp rest area), the second profile line extends from Schwerte-Ergste in the southeast via Dortmund-Syburg and Herdecke to Dortmund-Kirchhörde in the northwest. A few days before the measuring vehicles left the route on 20 February, geoscientists distributed the geophones along the route. The geophones were collected on 24 February. The research project and the seismic investigation are funded by the state of

ION agrees financial restructuring with shareholders ION Geophysical has completed its direct offering of 2,990,001 shares at $3.50 per share. The company intends to use the $10.5 million raised, excluding transaction expenses, for working capital. Chris Usher, ION’s president and chief executive officer, said, ‘It strengthens our balance sheet and provides additional flexibility to manage the business through the tail end of the pandemic. We

continue to proceed with the upcoming bond restructuring transactions and associated rights offering, pending shareholder approval, in early April.’ On 22 January the company’s shareholders voted 98% in favour of proposed bond restructuring, and 96% in favour of the associated increase to our available shares of common stock. It has also secured more than $20 million in backstop support for its rights offering,

which supporting bondholders had laid down a condition of their participation in the upcoming bond exchange offer. To address the upcoming maturity of the $120.6 million Second Lien Notes on 15 December 2021, ION executed a restructuring agreement in late December. The deal will extend the bond maturity by four years to December 2025 with a lower 8% interest rate.


Special Topic

UNCONVENTIONALS AND PASSIVE SEISMIC Large-scale exploration of shale oil and gas in America has driven innovation in the unconventionals sector in the past few years and some of the latest developments will be showcased here. Meanwhile, interest in passive seismic techniques, such as microseismic monitoring has continued to grow, driven by the success of such techniques in providing insights into subsurface geomechanical processes. Vasilii Ryzhov et al demonstrate the offshore deployment, acquisition and applicability of LFS to delineate hydrocarbon deposits in the North Sea. They show how low-frequency seismic sounding (LFS) technology has the potential to delineate oil and gas reservoirs to derisk drilling decisions and shorten the appraisal and development timeframe. Joshua Richard Williams et al discuss the development of an artificial neural network for classifying seismic triggers as events or blasts using source parameters estimated in real-time. Thomas L. Davis answers the question as to what natural fractures tell us about the origins of faulting in the Wattenberg Field in the Denver Basin. D Kühn et al present recent work on reservoir-triggered seismicity (RTS) from Koyna, western India, a prominent site where a large artificial water reservoirtriggered earthquake of magnitude 6.3 occurred on 10 December 1967. Majid Nasehi demonstrates potential for enhanced oil recovery in the Western Canada Sedimentary Basin (WCSB). Stephen A. Sonnenberg demonstrates how unconventional-style completions have unlocked resources in the Three Forks play comprising the Bakken petroleum system, a giant, continuous accumulation in the Williston Basin. They demonstrate the effective deployment of horizontal drilling and multi-stage hydraulic fracture stimulation.
