Title:    The Future of Land Seismic Acquisition

ABSTRACT:

The future of land seismic acquisition surveys is with data volumes recorded with single vibrators utilizing a short sweep on each source point (VP) implemented with fire-at-will technology (FAW). These source parameters coupledwith optimized receiver deployment will yield cost effective high trace density data volumes. High trace density is necessary for enhanced image quality through less aliased spatial sampling and increased migration multiplicity. The acronym FAW represents our terminology associated with the acquisition method that allows vibrator sets to initiate sourcing upon VP arrival. We define a short sweep as time duration of 4 to 8 seconds. Vibroseis sets are defined as one or more vibroseis units, electronically synchronized to act as a single unit. Also, shear and p wave vibroseis sets can be simultaneous sourced allowing for a cost effective shear wave subset volume to be acquiredduring a conventional p-wave survey. We were provided a 6 square mile laboratory by Pioneer Resources, located in the Permian Basin approximately 20 miles southeast of Midland, Texas. The processed data offers comparisonsfrom the ten 3D volumes. The volumes were acquired with seismic parameters ranging from conventional P and S wave sourcing to a unique P and S wave sourced volume with FAW technology. Analysis of the 3D data gives us confidence to support our declaration for the future of land seismic acquisition

BIOGRAPHY:

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 forty years of exploration experience in the energy industry with thirteenyears of 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).
