A recent geologic study may shed light on the New Madrid, a mid-western U.S. seismic zone that is much discussed but little understood.
Quality Control: In the world of seismic this could be a phrase to fear but objectivity is the better approach.
State-of-the-art seismic acquisition, processing and interpretation techniques continue to be keys that unlock the treasure for Forest Oil in South Africa.
State-of-the-art 3-D seismic technology led to a major gas discovery — and perhaps much more — in South Africa.
Tom Temple's poster on 'The Use of Seismic Stratigraphy for Waste Site Characterization' will be presented during the morning of Tuesday, May 13, at the AAPG Annual Meeting in Salt Lake City.
They're not just for oil anymore: Seismic technologies are proving their value in the environmental arena.
Seismic technology: What's ahead? A road full of advances in computing, digital recording, massive channel counts, 3-D imaging, time-lapse 4-D ... just to name a few.
Did you hear the one about the fella with a cell phone for an office and no seismic equipment, jockeying with the big seismic industry's guys for a job?
This month's column is by Jorge/Jordi Ferrer Modolell, general chair of the 2003 AAPG International Conference and exhibition in Barcelona, Spain.
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.

Physics is an essential component of geophysics but there is much that physics cannot know or address.

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.

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.
