New 3-D seismic data and the injection of CO have given new life to a 100-year-old oil field in Wyoming.

Dan Steward takes pride in doing a good job yet without calling attention to himself. That’s no small achievement. That play was the big reason why Steward was cited as the Explorer of the Year at the recent AAPG Annual Convention in Long Beach, Calif.

In last month’s Geophysical Corner we showed that fracture orientation across fractured-reservoir intervals can be determined by azimuth-based analyses of S-wave velocities and reflection amplitudes.

The success of technological plays such as the Barnett Shale and other shales has proven the potential of shale-gas resources -- and if the recent number of technical sessions, short courses and workshops on gas shales is any indication of its significance, gas shales will be an important component of the world gas supply in the future.

Since 1994, the Petroleum Technology Transfer Council (PTTC) has been a recognized force in the realm of technology transfer in the oil and gas industry.

Most rocks are anisotropic, meaning that their elastic properties are different when measured in different directions.

Students at the University of Calgary’s Department of Geology and Geophysics integrate maps and data to help predict where open fractures will deliver oil and gas to well bores from subsurface reservoirs.

The Energy Minerals Division is excited to present its technical program and activities for the upcoming AAPG Annual Convention in Houston April 9-12. EMD has a very attractive program and both EMD and AAPG members will be treated to a variety of technical sessions, short courses and a lignite field trip.

VG Abstract

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

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 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.
