'Sourced in part by the Eagle Ford Group, the Austin Chalk has been a hot spot for operators on and off for a century. The rise of horizontal drilling and hydraulic fracturing brought a renewed interest in the formation, which has produced new discoveries in Texas and Louisiana. Yet in parts of the Austin Chalk, extracting oil and gas can be extremely tricky. Several years ago, the Carbonate Reservoir Characterization Research Laboratory at the University of Texas began a project to analyze approximately 40 cores from the Austin Chalk – the first group to do so.

If recent events in the oil and gas sector, especially as it relates to the fallout and contraction from COVID-19, illustrate anything, it is the need for companies to create resilient businesses and business models. “That means having a business plan that anticipates and can adapt to changing conditions due to evolving environment, societal, and governmental pressures.” That’s Joseph R. Davis, independent direct at BKV Corp, an investment E&P firm. “You can’t separate ESG from sustainability,” he said, “for ESG is how business addresses sustainability.”

Understanding source rock provides a key to evaluating the hydrocarbon potential of super basins and an important tool for basin exploration. Geologists get the basics right, in general, but sometimes they might be thinking about source rock the wrong way. They are definitely talking about it in the wrong way.

Exact predictions of the future have always been close to impossible. For the oil industry today, they might be even harder than that. Some oil companies are taking a wait- and-watch approach to planning, as multiple unknowns face the industry in a period of extreme uncertainty. Trying to predict a precise outlook right now isn’t just foolish, said Mark Finley. It could be dangerous.

What is “brand”? The London-based Design Council notes that: “Brand is a set of associations that a person (or a group of people) makes with a company, product, service, individual or organization. These associations may be intentional – that is, they may be actively promoted by marketing and/or corporate identity – or they may be outside the control of the business.” For example, the growing belief among younger demographics that the fossil fuel industry represents the fuels of their parents.

Explorer President’s Column

“The only certainty in geology is the unexpected will happen” is a bit of wisdom my friend and mentor John Shelton likes to quote. If anything, in this environment, it’s an understatement. AAPG, our members and industry were hit with the perfect storm: —COVID-19, geopolitics and commodity prices. Of course, I don’t need to tell you about it. We have all adjusted to a new world, which includes quarantines, masks, eating in, ordering out, Zoom, MS Teams, etc. The dogs love it, the cats hate it. It’s been tough on all of us and my thoughts and prayers are with you and your families, especially those who have lost loved ones. So … how does all this impact your society?

I know I’m not alone. Each day, as part of my morning routine, just as reliably as I brush my teeth and brew strong coffee, I check the price that oil is trading for on global markets. How do I know I’m not alone? Because my first calls of the day – usually with AAPG leaders – usually begin or end with a reference to oil prices. We all know that watching the price of oil does nothing to boost demand, but still we watch, ever hopeful that today will be a good day in the markets.

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.

DL Abstract

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.

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.

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

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.

DL Abstract

Around 170 million years ago, the Gulf of Mexico basin flooded catastrophically, and the pre-existing landscape, which had been a very rugged, arid, semi-desert world, was drowned beneath an inland sea of salt water. The drowned landscape was then buried under kilometers of salt, perfectly preserving the older topography. Now, with high-quality 3D seismic data, the salt appears as a transparent layer, and the details of the drowned world can be seen in exquisite detail, providing a unique snapshot of the world on the eve of the flooding event. We can map out hills and valleys, and a system of river gullies and a large, meandering river system. These rivers in turn fed into a deep central lake, whose surface was about 750m below global sea level. This new knowledge also reveals how the Louann Salt was deposited. In contrast to published models, the salt was deposited in a deep water, hypersaline sea. We can estimate the rate of deposition, and it was very fast; we believe that the entire thickness of several kilometers of salt was laid down in a few tens of thousands of years, making it possibly the fastest sustained deposition seen so far in the geological record.

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.
