In the July 2002 'Geophysical Corner' we described a new fracture detection method incorporating a portable laserscan unit to completely image analog outcrops in three dimensions. This month we are going to explore how simple analysis of calibrated analog fracture models can enhance exploration and production in fractured reservoirs.

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.

On the arid high plains of northeast Wyoming, the town of Gillette has become a bona fide boomtown. And it's coalbed methane creating the frenzy. The Powder River Basin has become the site of the hottest natural gas play in the country, a region most so-called experts wrote off as a wasteland for the gas.

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.

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.

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

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.
