“Practical Considerations for Designing, Acquiring and Processing a VSP for Time-Lapse CO2 Injection Monitoring“
Richard Van Dok, Chief Geophysicist, Sterling Seismic Services
Borehole seismic (VSP) surveys can be an ideal tool for monitoring CO2 injection given their high degree of repeatability, low noise levels, overall improved resolution and reduced cost when compared to equivalent surface seismic surveys. This presentation will discuss the various options available for permanent, or semi-permanent, seismic monitoring using downhole receivers, including their benefits and limitations. In addition, some practical insights will be shared related to the design process and how this can ultimately affect the long-term monitoring plan for any given project. Ensuring the repeatability of the data acquisition is obviously critical, but time-lapse monitoring also requires careful attention to all aspects of the processing and analysis in order to preserve meaningful changes in the reservoir while removing or reducing other changes related to the different acquisition conditions. Some thoughts on time-lapse processing best practices will be also discussed.
Speaker Bio
Rich received his B.Sc. in Geophysical Engineering 1984 from the Colorado School of Mines. He joined Western Geophysical in Houston in June of 1984 and worked for them in various positions for just over twenty-two 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. He currently oversees all borehole seismic processing (3C geophone and DAS) and CCUS projects as well as all depth imaging at Sterling. 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.
