Seismic interpretation is fundamentally based on interpreting changes in amplitude.

During 2003, our societies — the American Association of Petroleum Geologists, the European Association of Geoscientists & Engineers, the Society of Exploration Geophysicists and the Society of Petroleum Engineers — held extensive discussions about working together to organize a new oil and gas conference and exhibition.

Increasingly sophisticated E&P tools have proven to work near-miracles in much of the oil patch -- but high-tech applications usually carry a correspondingly high price tag that would break the budget of the increasing numbers of small companies dotting the landscape.

The impressively large response to the call for papers is an indication that the 2004 AAPG International Conference and Exhibition in Cancun, Mexico, is shaping up to be one of the year's most important meetings.

A big challenge for modern seismic is the ability to image complicated structures. Fold and thrustbelts are characterized by rapid velocity variations due to juxtaposed rock types.

Honey, I shrunk the … vibroseis truck? Robert Stewart, a professor of geophysics at the University of Calgary (Canada), is the alter ego of the fictional movie scientist who accidentally shrinks his kids in an experiment that goes terribly wrong.

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.

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.
