The global shift from greenhouse gas-intense, carbon-based fuels toward alternative energy sources and technologies sometimes produces unintended negative impacts. Experts at the Bureau of Economic Geology at the University of Texas at Austin are mounting a major study of these effects – the Comparing Electricity Options research consortium – with the intention of helping to identify and mitigate such unintended outcomes.

In February, TotalEnergies announced a significant light oil discovery in the Orange Basin, offshore Namibia. Reuters reported a source suggesting that the Venus-X1 well may have found more than 1 billion barrels of oil equivalent. This was the second significant discovery announced in the basin that month. The offshore continues to deliver new oil and natural gas discoveries worldwide. And as this issue hits your inbox, the offshore is the primary topic of discussion in Houston as the 2022 Offshore Technology Conference returns to NRG Park from May 2-5.

Explorer Foundation Update

Geoscience education is essential to the AAPG Foundation. In fact, it’s promised right there in the Foundation’s mission statement, to “… support(ing) education and scientific activities in the field of geology.” Also crucial to the Foundation: engaging and informing the general public about the importance of energy, geology and the world in which we all reside. That’s why there are many, many Foundation programs supporting all those goals. But some Foundation-backed projects exist to do both at the same time – and one, in particular, is making a big impact on both students and the public by merging geology, geosciences and video production techniques into one informative, often timely and always accessible package.

Listening to “King of the Mountain” by Midnight Oil, a song about a foot race up the wickedly steep Mount Cooroora in Australia, prompted me to think about whether it is good to be the king, or to be in a position to just help others get to the top of the mountain. We do not need royal powers or superhuman running ability to make a difference for people participating in AAPG activities. Making a difference can be much simpler and just requires the will to make the climb and help others along the way.

The challenges in acquiring quality laboratory flow measurements in very low-permeability reservoir rock samples has furthered the development of image-based rock physics simulations of multiphase transport properties. The concept of “digital rocks” originated 50 years ago and has become more widespread recently with advances in imaging technology, computing power and robust algorithms for representing complex multiphase flow behavior at the pore scale. Simulation results based on high-resolution images have the dual role of complementing laboratory measurements on conventional reservoirs and acting as a stand-alone predictive tool for unconventional reservoirs where the very low permeability values limit what can be measured in the laboratory.

Explorer Historical Highlights

There are two main oil and gas producing sedimentary areas in France: the Paris Basin and the Aquitaine Basin. The presence of oil seeps and bitumen deposits has been known since ancient times in the western part of the Aquitaine basin, a 35,000-square-kilometer triangular polygon bordered to the north by the city of Bordeaux, to the east by Toulouse and to the south by the Pyrenees Mountain chain separating France from Spain. These hydrocarbon shows were observed close to surface anticlinal structures such as the Sainte-Suzanne dome, southwest of Pau or in the caprocks of salt diapirs at Salies de Bearn and Dax to the north.

In the first part of this series, we showed the energy transition will follow an “all of the above” trajectory, irrespective of aspirational messages. Our conclusions are based on the inherent limitations of wind and solar low-density energy machines for generating base-load power: low-density energy machines would cover hundreds of millions of acres. Also in part 1, we discussed Princeton University’s Net Zero America report, an outstanding, 18-author study of five models to de-carbonize the United States by 2050. The report does not mention environmental impact of LDEMs.

While it is evident that the world will rely on oil and gas for years to come, some industry geoscientists are paving a path toward a future in alternative energy and other geoscience-related careers. Geoscientists are needed for research and development in areas of geothermal science, minerals and mining, and carbon and energy storage. They also are needed for projects that require knowledge of geology, subsurface imaging, reservoir development, satellite mapping, geotraining, multiphysics and smart data solutions.

What seemed like excellent news for the oil and gas jobs outlook turned into something less positive for companies in the first months of 2022. Hiring increased, but a few areas saw more openings than applicants. However, job hunters and even those already employed in oil and gas got some welcome security and relief, as recent cycles of industry layoffs finally turned into a round of rehires and new hires. Analysts expect this job growth to continue for the foreseeable future.

Located in the Orange Basin, along the passive west coast of the continental margin that straddles the borders of South Africa, there has been a discovery of an oil province in Namibia – the offshore Graf and Venus fields – that likely contains billions of barrels of oil resources. That’s according to Robin Sutherland, an exploration manager for Monitor Exploration, a UK-based private exploration company involved in oil and gas exploration in Africa. Of equal importance, he said, is the recent drilling by ReconAfrica, which “clearly proves” that the Ovambo Basin, a large pre-Cambrian basin in the far north of Namibia, is oil bearing with very significant potential. “Both of these events represent major changes to our understanding of the potential of Namibia,” said Sutherland.

Sequence stratigraphy is a method for stratigraphic interpretation, pioneered by Vail and colleagues in the mid 70’s, which explains the complex geometries that sediments create as they fill accommodation in response to changes in rates of sedimentation, subsidence, uplift and eustasy. This method was developed based on observations and concepts developed as early as in the 1800’s. Based on this strong scientific foundation, pioneer work from Caster, Sloss, Wheeler, Campbell, and Asquith established the basis for the methodology. These researchers established a new way to correlate stratigraphic units, demonstrating the time-transgressive nature of lithostratigraphic formations.

This presentation and demonstration will focus on a machine learning workflow in the upstream Oil and Gas domain to predict formation tops by applying artificial intelligence and machine learning techniques to learn the well logs signatures. This deep learning model provides high quality predictions to aid the geologists in picking lithology markers consistently and in an accelerated fashion thus boosting their operational efficiency. The self-learning model, which is a unique differentiator of dataVediK and encompasses the detection of outliers and data quality issues and their subsequent validation and suggested corrections to improve the quality of data in an automated fashion during the model training process. The demo will then showcase a real-time drilling solution built using this ML model, whereby the formation tops are predicted, and the structural model is updated automatically as the GR log is acquired.

In the span of a mere few months, the much of the world went from a state of exuberant self-actualization to the most primal level of survival (health, food, shelter) insecurity. Consequently, the world has changed. Shock change due to pandemic-triggered chain reactions, supply / demand and price instability, rapid technological innovation, new plays and changing markets, distributed teams and workforces, the powerful force of social media, shortages of technical expertise, and supply chain issues have come together to create new challenges and opportunities for leadership. We will analyze how the issues relate to the oil and gas business (exploration, development, oilfield services, support services, financial sector) and we will propose solutions for immediate real-world emergencies, together with longer term challenges. In addition, we will evaluate what prominent thinkers and academics have written about leadership and strategic planning.

Engineering of wind farms, development of carbon sequestration projects in shelfal waters, the proliferation of communication cables that connect the world, all of these things suggest that it is time to re-examine what we know about shelf processes both updip-to-downdip and along shoreline, and the influence of shelf processes on erosion and transport of sediments.

In comparison with the known boundary conditions that promote salt deformation and flow in sedimentary basins, the processes involved with the mobilization of clay-rich detrital sediments are far less well established. This talk will use seismic examples in different tectonic settings to document the variety of shale geometries that can be formed under brittle and ductile deformations.

The Energy sector is a changing business environment. Throughout the 20th century fluctuations of oil supply and demand produced changes in the barrel price that pushed the growth or shrinkage of the industry. In this 21st century, new challenges such as diversification of the energy mix, boosting gas demand, require the exploration of critical minerals and development of new technologies as well.

President Biden has laid out a bold and ambitious goal of achieving net-zero carbon emissions in the United States by 2050.  The pathway to that target includes cutting total greenhouse gas emissions in half by 2030 and eliminating them entirely from the nation’s electricity sector by 2035. The Office of Fossil Energy and Carbon Management will play an important role in the transition to net-zero carbon emissions by reducing the environmental impacts of fossil energy production and use – and helping decarbonize other hard-to abate sectors.

VG Abstract

The carbonate sequences that were deposited in the now exhumed Tethyan Ocean influence many aspects of our lives today, either by supplying the energy that warms our homes and the fuel that powers our cars or providing the stunning landscapes for both winter and summer vacations. They also represent some of the most intensely studied rock formations in the world and have provided geoscientists with a fascinating insight into the turbulent nature of 250 Million years of Earth’s history. By combining studies from the full range of geoscience disciplines this presentation will trace the development of these carbonate sequences from their initial formation on the margins of large ancient continental masses to their present day locations in and around the Greater Mediterranean and Near East region. The first order control on growth patterns and carbonate platform development by the regional plate-tectonic setting, underlying basin architecture and fluctuations in sea level will be illustrated. The organisms that contribute to sequence development will be revealed to be treasure troves of forensic information. Finally, these rock sequences will be shown to contain all the ingredients necessary to form and retain hydrocarbons and the manner in which major post-depositional tectonic events led to the formation of some of the largest hydrocarbon accumulations in the world will be demonstrated.

DL Abstract

As oil and gas exploration and production occur in deeper basins and more complex geologic settings, accurate characterization and modeling of reservoirs to improve estimated ultimate recovery (EUR) prediction, optimize well placement and maximize recovery become paramount. Existing technologies for reservoir characterization and modeling have proven inadequate for delivering detailed 3D predictions of reservoir architecture, connectivity and rock quality at scales that impact subsurface flow patterns and reservoir performance. Because of the gap between the geophysical and geologic data available (seismic, well logs, cores) and the data needed to model rock heterogeneities at the reservoir scale, constraints from external analog systems are needed. Existing stratigraphic concepts and deposition models are mostly empirical and seldom provide quantitative constraints on fine-scale reservoir heterogeneity. Current reservoir modeling tools are challenged to accurately replicate complex, nonstationary, rock heterogeneity patterns that control connectivity, such as shale layers that serve as flow baffles and barriers.
