Chevron Initiates Water Injection to Boost Gulf of Mexico Oil Recovery - 04 September, 2024 07:30 AM

Explorer Article By Louise Durham

Life was fairly predictable prior to 1973, Texas State Geologist Scott Tinker noted during a 'power lunch' presentation at the recent APPEX event. Then the Arab oil embargo hit, triggering the first major energy price spike.

Time Is Proving the Value of 4-D

Time-lapse, or so-called 4-D, seismic technology is proving its worth as a reservoir management tool -- not just on new fields where the technique is applied from inception, but at all stages of a field's lifecycle.

What's (Not) Happening Is Erie

The reality of significant natural gas potential found in the Great Lakes region of North America continues to emerge, and states bordering the lakes are becoming yet another battleground for the U.S. energy debate.

Sneider: A Star on the Team

Houston geologist Robert Sneider and British poet John Donne share a basic philosophy: No man is an island entire of itself. It's the people that make a difference along the way.

Precision Is Now the Norm for Pool Development

The storage field geologist, while worrying about such things as spill points and thief zones, is primarily concerned with “location, location, location.”

Probing What Makes the Crust Strong (or Weak): Insight from Boreholes, Earthquakes, Active Fault Systems, and Toy Models

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.

Estimating, Benchmarking, and Managing Subsurface Uncertainty: Principles and Examples

Subsurface risk and uncertainty are recognized as very important considerations in petroleum geoscience. And even when volume estimates are relatively accurate, the reservoir characteristics that determine well placement and performance can remain highly uncertain. In analyzing results and work practices, three aspects of uncertainty are reviewed here.

The Assembly of Pangea, a View from Laurentia: Paleozoic Orogenies and their Impact on Basin Evolution and Petroleum Systems

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.

The Shelf is a Dangerous Place: Surfing the Cretaceous Seaways

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.

Atmospheric and Social Climate Change: Implications for the Future Geoscience Workforce

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.

Tectonic Controls on Source Rock Deposition

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.

Salt versus Shales in Continental Margins and Orogens

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.

Shaping New Leadership in an Evolving Energy Business

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.

Submarine-Channel Evolution From Seismic Stratigraphy & Numerical Models: Patterns and Predictions Revisited

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.

How Orogens Could Collapse Forming Sedimentary Basins: The Case of the Betic-Rif Orogen

The Betic hinterland, in the westernmost Mediterranean, constitutes a unique example of a stack of metamorphic units. Using a three-dimensional model for the crustal structure of the Betics-Rif area this talk will address the role of crustal flow simultaneously to upper-crustal low-angle faulting in the origin and evolution of the topography.
