Title: Design, acquisition and processing of three Permian Basin 3D VSP surveys to support the processing and interpretation of a large 3D/3C surface seismic survey.
Richard Van Dok* and Brian Fuller, Sterling Seismic and Reservoir Services;
Ron Bianco, Fasken Oil and Ranch, Ltd.
Summary: Three 3D borehole seismic (VSP) surveys were designed and acquired in Andrews and Ector Counties, Texas in 2019 to provide data to support the processing and interpretation of a
high-fold multicomponent 3C/3D survey. The three downhole receiver well locations were chosen in available wells in three distinct geological settings within the area covered by the surface seismic surveys. Large aperture 3-component (3C)
borehole geophone arrays and both P-wave and S-wave vibrator sources were utilized, providing valuable time-depth and velocity information. In addition to the travel time information, high-resolution VSP reflection images were produced for the various wave types recorded (P-P, P-S and SS) which gave useful insights into the signal properties of each.
Richard Van Dok
Chief Geophysicist - Sterling Seismic & Reservoir Services
Rich received his degree in Geophysical Engineering from the Colorado School of Mines in 1984. He joined Western Geophysical in Houston in June of 1984 and worked for them in various positions for just over 22 years, ultimately attaining the position of Senior Area Geophysicist. Throughout his career he has been involved in all phases of surface seismic data processing including land, marine, OBC and multicomponent applications. In 1988 he transferred to Western’s Denver office. In 1996 he began working on azimuthal anisotropy issues related to both P-waves and converted waves primarily for fracture detection and reservoir characterization. In 2006, he left WesternGeco and became a partner in HiPoint Reservoir Imaging and Apex HiPoint (later to become Sigma3) to focus on all aspects of borehole seismic acquisition and processing – including active VSP imaging and passive hydraulic fracture monitoring. With Sigma3, Rich was the principal processor of borehole seismic datasets from zero-offset, 3D and 4D and converted wave VSPs. Rich joined Sterling Seismic in January 2019 and continues his work with advanced VSP and surface seismic processing and imaging.
Rich has co-authored numerous papers and articles on these subjects for the SEG, EAGE, CSEG, AAPG and various other local geophysical societies. In 2007, Rich and his co-authors, were presented with the SEG Best Paper Presentation Award at the SEG Annual Meeting. He and his co-authors were also presented with the Best Paper in The Leading Edge Award for 2011.
VP of Reservoir Geosciences - Sterling Seismic & Reservoir Services
Brian has 38 years’ experience applying and developing seismic technology. His current interest is in determining geomechanical properties of reservoirs via processing of time-lapse DAS seismic data recorded in horizontal wells.
Brian started in the oil industry in 1980 with Amoco/Denver as an exploration geophysicist. He then did a stint in graduate school at the University of Wyoming earning Masters and Doctoral degrees in Geophysics. Later industry work kept him in borehole seismic processing and software development and in 2008 he co-founded HiPoint Reservoir Imaging with Marc Sterling and others. HiPoint Reservoir Imaging was sold to Sigma Cubed in 2013 where Brian worked until March, 2018.
Brian joined Sterling Seismic & Reservoir Services with the primary goal to build a world-class seismic and geomechanics reservoir team that provides engineers with information they need to maximize production at the lowest possible cost.
Senior Staff Geophysicist - Fasken Oil and Ranch, Ltd.
Ron received both his Bachelor’s and Master’s degrees in Geophysics from Texas A&M University in 2011 and 2013. He began his career with Apache Corporation prospecting oil and gas wells across the Permian Basin, South Texas Eagleford, and GOM shelf. Ron joined the Fasken Oil and Ranch exploration team in 2016 where he continues to prospect for oil & gas production/disposal wells, induced seismicity modelling, and oversees 3D seismic acquisition, processing, and interpretation.
