A multi-component seismic project was completed in May of 2006 in the northern portion of the Midland Basin of West Texas. The project consisted of a conventional multi-component acquisition program followed by an experimental multi-component acquisition program. During the conventional phase of the project each of the required component modes P, Sx, and Si were sourced independently over the 25 square mile project area. During the experimental portion of the project numerous source points were replicated using simultaneous acquisition of the required component modes to validate the application of High Fidelity Vibratory Seismic (HFVS) technology to multi-component seismic data acquisition. The HFVS scheme allows data from multiple vibratory sources to be simultaneously collected during the acquisition phase and separated in the processing stage. The test provided two data volumes acquired with the concurrent recording of the P, Sx and Si source modes and a third volume recorded with concurrent Sx and Si source components. The conventional P and S wave data provide a baseline for comparison with the experimental volumes acquired with the HFVS technology. The HFVS recording methodology has the potential to increase the production rate of a multi-component survey by a factor of three.
Alison Weir Small received a BS (1984) in Geology from Southern Methodist University and an MS (1986) in Geophysics from Pennsylvania State University. Alison worked for Mobil Exploration and Producing US from 1988 through 1993 in the Midland production office. She worked as an asset team Geophysicist interpreting seismic data in and around asset team production in the Permian Basin. Alison also worked with engineers and geologists on producing property Reservoir Management Teams. Alison took time off from 1994 through mid 2002 to raise a family. In 2003 she began consulting for Parallel Production Corporation in Midland, Texas. At Parallel, Alison has supervised the acquisition and processing of 25 square miles of multi-component seismic data over a producing field in Scurry County, TX and has begun interpretation of the data. Other project areas have included New Mexico and other counties of the northern Permian Basin. Alison is currently President of the Permian Basin Geophysical Society and is a member of the Society of Exploration Geophysicists.
James Walter (Tom) Thomas received a BS (1976) and MS (1980) in Physics from Pittsburg State University. From 1976 to 1981 he taught secondary school math and science and served as a varsity football/track coach. From 1981-2002 he worked for Phillips Petroleum, joining Dawson Geophysical in the fall of 2002, He has over twenty-five years of exploration experience in the energy industry with thirteen years of actual field experience with 2D and 3D production and research seismic crews. He is a recognized leader in the geophysical sector for the innovation and application of 3D seismic acquisition and specialized processing techniques. His current interests are concentrated in the development and application of seismic technology for Dawson Geophysical Company. Tom holds patents in the field of seismic data acquisition and processing and has published his concepts and methods in the geophysical literature. He is a member of the Society of Exploration Geophysicists, the Tulsa Geophysical Society, Permian Basin Geophysical Society, and Sigma Pi Sigma (Physics Honor Society).
