Don't believe it when some of the pundits tell you South Louisiana is 'all drilled up.' Indeed, there's compelling evidence that the onshore region harbors a vast storehouse of hydrocarbons yet to be tapped by the drillbit.

With a patented technology that allows it to shoot seismic so it does not disturb urban areas, one Denver-based company is moving into suburbs and other cityscapes to search for oil and gas deposits.

In a perfect world, direct hydrocarbon indicators would be just that -- direct hydrocarbon indicators. But that term is a misnomer that since its inception has plagued the exploration business.

There has always been a slight element of mystery surrounding those seismic squiggles for geologists, even for all the geologists who know how to work with seismic data.

Once data compression for geophysics was criticized for promising more than it could deliver, but no more -- improved techniques have made it a reality for the industry.

DL Abstract

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.

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

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.
