Oil has flirted with 30-plus bucks a barrel, gasoline prices have soared into the stratosphere, one presidential candidate wants to open the long-off-limits Arctic National Wildlife Refuge to E&P while his opposition spouts the time-worn rhetoric about Big Oil gouging the public.

Area-wide lease sales, inaugurated in 1983, provided the oil industry an opportunity to explore for oil and gas in the deep water Gulf of Mexico, a southern extension of the oil-rich offshore Louisiana shelf province.

In this computer age it's easy to lose sight of the all-important fact that those gee whiz computer graphics and models that so beautifully depict the subsurface of the earth still have to start with the basics. The geologic data and rocks.

Stormy times brought out the risk-avoiders in the oil industry -- but now that demand for exploration is growing, will visionaries and visualists have their day in the sun?

New computer programs were designed by Shell Oil during that decade to measure seismic amplitude changes and pay thickness, and -- most importantly -- seismic data was being calibrated with petrophysical data.

The Louisiana Independent Oil and Gas Association (LIOGA) is determined to prove that a $60-per-acre seismic fee being levied by the Department of Wildlife and Fisheries (DWF) violates the constitution of the state of Louisiana.

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

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

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.
