You’d have to call leasing in the Gulf of Mexico more focused than frenetic.

For two years the Minerals Management Service (MMS) and the NOAA Ocean Exploration had expeditions in the Gulf of Mexico. The intent was to learn about chemosynthetic communities associated with surface gas hydrates, which may be used as a clean-burning fuel.

The use of 3-D seismic data has become so commonplace in the E&P world that for the most part it’s now considered just part of the everyday routine.

As seismic interpreters, most of us believe that robust reflection events are associated with drilling targets. In this article, we look at the opposite principle as: “Drill where there is no reflection signal.”

Read an interview of U.S. Geological Survey Director Mark Myers. He's an AAPG member, was nominated by President Bush and confirmed by the Senate in 2006, and heads up an entity that has more than 10,000 scientists, technicians and support staff. It covers a range of issues, from research to funding to the tricky areas of politics and science.

Don't feel bad if you haven't grasped the uses and benefits of geophysical tools in unconventional plays -- you're not alone. But here's something you need to know.

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.
