The Anadarko Basin granite wash play has been considered difficult to interpret both geologically and geophysically. Consequently, the application of seismic attribute analysis to mid-continent washes has not been widely published.

With technical sessions designed to have cross-discipline appeal across the industry, Buford Pollett, chairman of the AAPG technical subcommittee for OTC, said this year’s topics were specifically chosen to attract a broad spectrum of professionals.

Spectral decomposition of seismic data helps in the analysis of subtle stratigraphic plays and fractured reservoirs. The different methods used for decomposing the seismic data into individual frequency components within the seismic data bandwidth serve to transform the seismic data from the time domain to the frequency domain– and generate the spectral magnitude and phase components at every time-frequency sample.

The Upper Jurassic Smackover formation in northern Louisiana and surrounding states has been explored and drilled for decades, but has only recently seen the sophisticated approach needed to decipher its challenging geology.

When 3-D seismic technology became a must-have tool for the E&P crowd beginning in the mid-1990s, there was considerable scurrying to get up to speed on this then-daunting high-tech application. Even today, it’s not uncommon to see a non-geophysicist’s eyes glaze over when a discussion turns to even basic seismic terminology like P-waves, which move through both solid rock and fluids, and S-waves, which travel only through rock.

Like much of the technology used in the oil and gas industry, advances in the geophysical realm have evolved somewhat sporadically, yet with great impact overall.

If operators take the “glass half full” approach and use their idle time wisely during the industry’s current downturn, the seismic industry – at least parts of it –could experience an upswing.

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.

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.
