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.

DL Abstract

For well over a century there have been conflicting indications of the strength of the crust and of faults and what controls them.  Much of our ignorance comes quite naturally from the general inaccessibility of the crust to measurement--in contrast with our understanding of the atmosphere, which is much more accessible to observation as well as more rapidly changing.  Crustal strength is best understood in deforming sedimentary basins where the petroleum industry has made great contributions, particularly in deforming petroleum basins because of the practical need to predict. In this talk we take a broad look at key issues in crustal strength and deformation and what we can learn from boreholes, earthquakes, active fault systems, and toy models.

Local sea-level changes are not simply a function of global ocean volumes but also the interactions between the solid Earth, the Earth’s gravitational field and the loading and unloading of ice sheets. Contrasting behaviors between Antarctica and Scotland highlight how important the geologic structure beneath the former ice sheets is in determining the interactions between ice sheets and relative sea levels.

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.

DL Abstract

Three-dimensional (3D) seismic-reflection surveys provide one of the most important data types for understanding subsurface depositional systems. Quantitative analysis is commonly restricted to geophysical interpretation of elastic properties of rocks in the subsurface. Wide availability of 3D seismic-reflection data and integration provide opportunities for quantitative analysis of subsurface stratigraphic sequences. Here, we integrate traditional seismic-stratigraphic interpretation with quantitative geomorphologic analysis and numerical modeling to explore new insights into submarine-channel evolution.

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.

While there are many habitats that are associated with the deposition of organic-rich marine and lacustrine source rocks, one important pathway is linked to the onset of increased basin subsidence associated with major tectonic events. A key aspect is that this subsidence is spatially variable, with the uplift of basin flanks contemporaneous with the foundering of the basin center, resulting in a steeper basin profile.

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.

DL Abstract

Climate change is not only happening in the atmosphere but also in the anthroposphere; in some ways the former could drive or exacerbate the latter, with extreme weather excursions and extreme excursions from societal norms occurring all over the earth. Accomplishing geoscience for a common goal – whether that is for successful business activities, resource assessment for public planning, mitigating the impacts of geological hazards, or for the sheer love of furthering knowledge and understanding – can and should be done by a workforce that is equitably developed and supported. Difficulty arises when the value of institutional programs to increase equity and diversity is not realized.
