Picking prospects in tight gas sands using multiple azimuth attributes

The first phase of a U.S. Department of Energy (DOE) funded project has been successfully completed. A drill site has been recommended and both the operator and DOE agree that it should be drilled. This article details the justification and methodology employed to spot this well, an Encinal Sand fractured-reservoir prospect. It was spotted by applying modern seismic-processing techniques followed by rigorous analysis of azimuth-dependent seismic attributes, and well-log data to qualify areas of high natural-fracture density.
