Seismic Reservoir Characterization, also known as reservoir geophysics, has evolved over the past several years into a multidisciplinary, business-critical function in most ED&P organizations. Sheriff defines reservoir geophysics as “The use of geophysical methods to assist in delineating or describing a reservoir or monitoring the changes in a reservoir as it is produced.” Reservoir geophysics is applied across a wide spectrum of the oilfield life cycle, from discovery and early development, to tertiary recovery. One critical part of this process is careful analysis and understanding of petrophysical properties from well logs and core data (seismic petrophysics).
This presentation illustrates why seismic petrophysics is so important and shows how carefully constructed synthetic models can help the geoscientist interpret acoustic and elastic impedance inversion from seismic data.
Joel Walls obtained his Ph.D. in geophysics from Stanford University in 1983. He has been active in research and technical services related to core analysis, rock physics, and seismic reservoir characterization. Dr. Walls founded PetroSoft Inc. in 1992 to bring rock physics technology to the desktop. Rock Solid Images (RSI) was founded in 1998 from the merger of PetroSoft Inc., Seismic Research Corp., and Discovery Bay. RSI has 30 employees in Houston and Oslo, Norway. Dr. Walls is Vice President of New Business Development.
