Shale resource plays are associated with low permeability, so hydraulic fracturing is required for their stimulation and production. In order to enhance the flow of fluids with hydraulic fracturing, it is vital to understand the stress field distribution. The efficiency and effectiveness of a hydraulic fracture stimulation are predicated on adequate horizontal well placement in the subsurface. For that purpose, the horizontal wells are usually drilled in the direction of minimal horizontal stress so that hydraulic fracturing takes place in the direction of maximal stress that ensures better reservoir contact and production, which also depends on how a complex fracture network is created by induced fractures.

In 1994, while chairman and CEO of Barrett Resources, I got a call from my good friend Ray Thomasson, who said, “Bill I have a prospect Larry McPeek has worked up in the Wind River Basin that you might find interesting.” I’d worked every feature of geology in Wyoming’s Wind River Basin and was familiar with about every well drilled there during my career, so I frankly considered myself somewhat of an expert on the basin ... The Cave Gulch Prospect was located along the Owl Creek Thrust in a geologically complex area.

Proposals to ban hydraulic fracturing in the United States have drawn a wide range of responses from analysts, with projected effects ranging from cataclysmic to trifling. Legislation to phase out fracturing was introduced in both the U.S. Senate and House of Representatives earlier this year. That turned up the heat on the controversy, as did the emergence of Sen. Bernie Sanders as the frontrunner for the Democratic presidential nomination. Sanders and Sen. Jeff Merkley introduced a bill titled the “Ban Fracking Act” in January.

Now referred to as a “super basin,” the Gulf of Mexico Basin has joined other top super basins in the world that, despite their maturity, have the potential or have proven to be significant new plays all over again. The driving force behind this renaissance is, for a large part, the evolution of technology over the last two decades that has jumpstarted both offshore and onshore basins.

Presented by Kevin C. Hill, Associate Professor, University of Melbourne Gravity modelling of Australia's southern margin reveals that the initial rift with Antarctica was beneath the current Ceduna Delta. A regional, high-quality seismic traverse from the coast to oceanic crust across the Bight Basin has been assembled and interpreted in detail, then balanced, restored, decompacted, and replaced at paleo-water depths. The Late Cretaceous Ceduna Delta developed above a Late Jurassic-Early Cretaceous rift basin in three stages punctuated by significant pulses of uplift and erosion across areas >100 km wide and with up to 1 km of erosion. The Cenomanian White Pointer delta prograded into deepening water and hence underwent gravitational collapse. This was terminated in the Santonian when the Antarctic margin was pulled out from below, thus supplying heat to a remnant thicker outer margin crust, causing doming and erosion. Importantly, this established the saucer-shaped geometry of the Ceduna Delta that persisted throughout its development, so that any hydrocarbons generated in the southern half of the basin would have migrated towards this outer margin high. The Tiger Formation was deposited in shallow water in a full rift basin prior to breakup, which was followed by regional thermal subsidence. The Hammerhead delta developed on the newly formed passive margin but was terminated by another pulse of uplift and erosion, perhaps associated with a change in plate motion at the end of the Cretaceous. The finite element modelling of this proposed tectonic evolution will test its validity and predict hydrocarbon generation and migration through time.

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.

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.

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.

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.

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

Paleozoic North America has experienced multiple mountain building events, from Ordovician to Permian, on all margins of the continent. These have had a profound effect on the resulting complex basins and their associated petroleum systems. Subsequent uplift, erosion and overprinting of these ancient systems impedes the direct observation of their tectonic history. However, the basin sedimentary records are more complete, and provide additional insights into the timing and style of the mountain building events. In this study, we employ ~90 1D basin models, ~30 inverse flexural models, isopachs, and paleogeographic maps to better understand the Paleozoic history of North America.

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.
