Three-component 3-D (3C3D) seismic data were analyzed in this study to determine whether P or C wavefields exhibit azimuthal variations that allow the principal axis of anisotropy to be determined across a fractured interval of McElroy field, West Texas. Preliminary data interpretation implies that any azimuth-dependent seismic properties will be modest, but additional analyses will be done before the study period ends.
An extensive subsurface database was compiled to support the seismic interpretation.The study was conducted over that part of McElroy field in West Texas operated by Chevron/Texaco, using data and co-funding provided by the operator. This study was funded by the U.S. Department of Energy.
