This report details the field work undertaken Blackhawk Geosciences and Lynn, Inc. during August 1994 to July 1995 at a gas field in the Wind River Basin in central Wyoming. The field surveys were performed for the Department of Energy, Morgantown Energy Technology Center, under Contract No. DE-AC21-94MC31224, "Naturally Fractured Tight Gas Reservoir Detection Optimization". The work described herein consisted of four parts: -9C VSP in a well at the site: - Additional Processing of the previously recorded 3-D survey at the site -Multicomponent feasibility studies during the 3D P-wave survey on the site, and Minivibrator testing -Planning and Acquisition of a 3-D, 3-C seismic survey The objectives of all four parts were to characterize the nature of anisotropy in the reservoir. With the 9C VSP, established practices were used to achieve this objective in the immediate vicinity of the well. The additional processing of the 3- D uses developmental techniques to determine areas of fractures in 3-D surveys. With the multicomponent studies, tests were conducted to establish the feasibility of surface recording of the anisotropic reservoir rocks. The 3-D, 3-C survey will provide both compressional and shear wave data sets over areas of known fracturing to verify the research.
