Seismic Marine Sources: State of the Art

A new focus within marine sources is yet drawing ever-increasing expectations in the industry to meet key evolutions in offshore seismic acquisition. The environmental impact of sources requires due assessment and mitigation measures, lower frequencies are more than ever expected, and the final application steadily transitions from hydrocarbons to new energies. This workshop intends to draw a state of the art of existing and expected solutions to address at best a changing environment.

Geostatistics and its Latest Developments Using Machine Learning Methods

The main objective of the workshop is to share and discuss the place of geostatistics in the world of AI and machine learning applied to geosciences.

Since its inception in the 1970s, geostatistics has developed in two main areas, spatial statistics and probabilistic modeling. Its progress and acceptance by the geosciences community have always been conditioned by computing power and costs. In the digital age, these constraints have disappeared, unleashing the power of geostatistical algorithms to best valorize large seismic and well data sets.

Geostatistics is poised to address two major challenges facing operating companies: How best to manage uncertainty and how to ensure the transfer of in-house expertise to the next generation of digital geoscientists?

Experts, academics, software developers and users will come together to share their experiences, explain how they are integrating AI into their developments and operations today, and what key performance indicators they offer.

Fault and Top Seal Essentials

Top and fault seal assessment will play a pivotal role not only in the development of new oil and gas prospects in mature hydrocarbon provinces, but also in numerous emerging low carbon geoenergy and subsurface storage applications such as hydrogen storage, CO2 sequestration, geothermal energy recovery, etc. This workshop aims at providing a broad overview of fault and top seal research trends in industry and academia and facilitating a discussion about future development needs based on keynotes and invited talks delivered by leading experts in the field. These will be selected based on cornerstone presentations and contributions of the latest major events and key journal publications, complemented by experience sharing from practical examples of the industry. The workshop should be highly interactive, and topics should be developed along the way based on the input of the speakers and participants.

Designing the Future of the E&P Business

The future of the E&P industry is in flux as we transition from our traditional oil and gas production business to something new and uncertain. There are multiple alternatives and possible futures that we can design and construct together to develop sustainable business models that enhance our quality of life and contribute to meeting environmental commitments. We propose a workshop to explore our possible futures and the role of technologies, organizations, and people in driving the systemic transformations needed to achieve a more sustainable and just future for all. We propose a one-day workshop split into three stages. 1) An introduction to the energy transition and systems transformation topics, including a range of speakers who will share their ideas and views about future business plans to give the audience food for thought that will be helpful for the next stage. 2) A workshop based on the systems thinking approach and a cognitive mapping tool (online) to organize the audience in groups and ask them to participate actively and co-design the strategies to meet three or four possible futures. Finally, 3) we facilitate a discussion where the groups can share the results from stage two with the other groups and present the alternatives and strategies to achieve those futures.

Creating space for reflection and dialogue where multiple perspectives can be shared and listened to can be beneficial in answering questions such as: what does the future look like? How are the strategies of the oil and gas companies connected to other sectors? What are the opportunities to drive natural and sustainable transformations? Where to start?

The outcome of the workshop will be an improved understanding of possible business model pathways and their impact on what their future might look like. Also, it provides tools and methods that can be used within the companies to explore alternatives for their business and strategies.

Geoscience Driving the De-risking of Commercially Viable Geothermal Systems in Europe

The workshop will cover geoscience topics related to exploration, production, and monitoring associated with the de-risking of commercially viable geothermal systems in Europe. The impacts of both established and emerging technologies will be discussed, including active and passive seismic, as well as multiphysics techniques. Along with the utilization of existing oil and gas data and technologies (e.g., drilling, completions, infrastructure). The workshop will focus on the requirements for commercial geothermal systems and will include opportunities for co-production which can impact the potential success of a project. Attendees are encouraged to share their experiences and openly discuss the challenges facing the industry today.

Natural Hydrogen Exploration

There are several types of plays for natural hydrogen exploration which appear to be very similar to those the oil and gas industry is used to. These include cases where there is a functioning trap, due to effective top seals. Examples can be found in pre-salt traps where hydrogen has been documented as part of existing hydrocarbon accumulations (examples: Dnieper-Donets Basin, Ukraine, and Amadeus Basin, Australia). Another somewhat unusual trapping has been documented in the first hydrogen field discovery in Mali where the top seal is provided by a set of dolerite sills. In these cases, one expects finite hydrogen resources in place and the critical question becomes the recharge rate for commercial production.

Another group of natural hydrogen targets revolve around mega-seeps (fairy circles, e.g. East European Craton) and smaller, fault-controlled seepages to the surface (e.g. French Pyrenees). These plays have no traps, no seals and, therefore, they do not find a proper analogue in oil and gas exploration workflows. Yet, because these seeps correspond to ongoing charge in a dynamic, truly renewable system, if they represent a steady-state process, one could expect infinite resources via a low-flux hydrogen “farming” process. For commercial hydrogen production in this case, therefore, a totally new technological approach will be required, not existing in the hydrocarbon industry at all.

This workshop is intended to capture the state-of-the-art for hydrogen exploration discussing various case studies, including methodologies applied and technologies involved. Since gold hydrogen exploration is really in its infancy worldwide, this workshop aims to promote collective thinking about the possible ways forward.

FWI Imaging

In recent years, Full Waveform Inversion (FWI) has evolved beyond a tool for velocity model building, into a viable alternative to conventional subsurface imaging. Modern implementations of FWI utilize more of the seismic wavefield, over a broader bandwidth, to derive images of the subsurface with improved illumination and resolution when compared to traditional imaging approaches. Underpinning the success of these methodologies is a rich and rapidly growing area of research, from which a multitude of technologies has emerged, ranging from alternative objective functions to new wave equation parameterizations. The objective of this workshop is to review the latest developments in these areas, highlight successful approaches, such as FWI Imaging (also known as FWI-derived reflectivity), and to discuss remaining challenges. We will also seek to understand the connection between the FWI-based methods and related strategies such as Least Squares Reverse Time Migration (LSRTM).

Seismic Interferometry: New Advances and New Applications

Retrieving responses between receivers or sources is the base of seismic interferometry. One of the main applications is in passive seismics, e.g., the possibility of using ambient-noise records instead of performing costly active seismic acquisitions. Another application is of using already acquired active-source data for retrieval of complementary arrivals. One of the main purposes of application of seismic interferometry is for building velocity models, which can be interpreted in terms of geological structures or used for other applications (e.g., statics computation, FWI, etc.), and imaging with retrieved reflections. But later advances show the possibility of performing reservoir monitoring, determining attenuation parameters, suppression of surface waves, retrieval of first breaks, etc.

This workshop intends to connect practitioners applying seismic interferometry at different scales with different objectives. Participants will contribute case studies, highlighting both the successful and the challenging aspects of their work, and share ideas on the latest algorithms and applications.

Integrated Geochemistry Technology for Engineering Applications

Historically geochemistry has mainly served exploration objectives. Rarely, you might hear about using geochemistry technology for production allocation in the past, but broad adoption of the tools available has yet to occur despite an extensive literature base (Slentz, 1981; Cubitt & England, 1995; Cubitt et al. 2004; Jweda et al. 2017). Changes are coming though, cross-discipline technologies are emerging, and cost-efficient geochemical solutions have been implemented to support important operational decisions.

Along with digitalization in the oil industry, a large amount of subsurface data has been made available, and the divide between geoscience and engineering is diminishing. New integrated geochemical technologies lead to many engineering applications in the oil industry. The engineering applications include optimized drilling targets, well placement, completion, production optimization, and reservoir management. In addition, the new applications also cover well integrity, production targets, and Plug and Abandonment (P&A) in the overburden.

If you wish to keep abreast of the new developments and participate in discussions on how these workflows, methods and tools are optimally integrated, then we look forward to having an in-depth discussion in the workshop at EAGE Annual in 2023.

The Role of Near-Surface Geophysics and Engineering in Renewable Energies and Low-Carbon Economy Transition

Advanced geophysical techniques are required to ensure the successful and efficient use of renewable energies and to fast-track the transition into a global low-carbon economy. The interplay between engineering and geophysics is a key factor in improving renewable resources exploration, and supporting storage of CO2 and nuclear waste. In this full-day workshop we will provide the framework to tackle these issues in a varied format, ranging from panel discussions with Q&A, community-led groupwork and presentations, invited speakers and a poster session / networking event. The aim of this workshop is to bring together industry professionals with academics and practitioners in a collaborative environment as society and governments strive toward a low carbon and more sustainable future.

Last European Frontiers

For a sustainable future, replacing crude oil and natural gas as the dominant elements in the global energy supply with lower carbon footprint sources is a major challenge on its own. It is even more so in Europe given the energy supply security issues highlighted recently due to the ongoing war between Russia and Ukraine.

To work towards a future energy mix which could meet the goals of the Paris Agreement, the increasing energy demand will dictate the exploration and production of low carbon intensity and cost efficient “advantaged” hydrocarbons.

A good example of an advantaged hydrocarbon is biogenic gas which can be found in large quantities in offshore regions around Europe, such as in the Mediterranean and the Black Sea.
In addition, thermogenic gas may be found at greater depth in established hydrocarbon basins where the risk and cost of considering thee targets prevented exploration to date. There are several basins in Europe which still have plays which have not been fully explored. Last exploration frontiers also include thrust-fold belts and volcanic basins in the broader European region with considerable gas potential.

Since hydrocarbons cannot be entirely replaced by greener geo-energy solutions in the next few decades, a deliberate effort is needed to focus the carbon capture and storage capacity that will be needed to mitigate the consequences of the ongoing, but slowly decreasing reliance on fossil fuels. Given the increasing focus on low-carbon geo-energy solutions, the European region needs a modern re-evaluation of the subsurface geo-energy potential not related to hydrocarbons. For example, the willingness to interpret a collage of “old” 2D seismic reflection data could provide critical new insights in many other underexplored basin segments globally in the context of the energy transition. Oil and gas companies, given their unique subsurface legacy data sets, will play a key role in the re-assessment of “forgotten” basin segments worldwide.

This workshop is intended to capture the latest ideas about the last exploration frontiers in Europe discussing various case studies, including new plays and underexplored basin segments considered and/or innovative technologies involved.

Distributed Fiber-Optic Sensing in Geotechnical Engineering and the Energy Sector

Distributed fiber-optic sensing refers to a family of technologies that enable asset owners and operators to retrieve vital data from within structures over long lengths and at high rates and resolutions. Optical fibers, deployed as sensors over tens of kilometers, can deliver data on acoustics, static and dynamic strain, temperature and many other properties that contribute to efficacy enhancement in production and exploration, as well as risk management during construction and operation – of tunnels and roads, boreholes and wells, slopes and embankments, and any other element of today’s critical infrastructure.

The one-day workshop will focus on practical insights from successful monitoring projects, sharing hands-on experience on installation, operation and data handling. The workshop will bring together application specialists from industry and academia with anybody who wants to learn how to use this powerful technology.
