Integration of uncertain subsurface information into multiple reservoir simulation models

Successful appraisal and development of oil and gas fields requires the integration of uncertain subsurface information into multiple reservoir simulation models. This information includes seismic data, various types of well data, and geologic concepts. Over a period of five years, a workflow was developed by various organizations in conjunction with BHP Billiton Petroleum. This distinctive approach focuses first on building mesoscale reservoir models that can be constrained by seismic data (typically with a resolution up to the strati- graphic seismic loop scale, see Prather et al., 2000), then introducing the finer scale geologic concepts and well data needed for reservoir simulation models (stratigraphic first and second-order subseismic scale, where each order is about a factor of three in size) via a downscaling step that honors mesoscale model constraints. Uncertainty and correlations of the well and seismic measurements are always taken into account. In fact, they are necessary to be able to combine the various measurements. Bayesian probabilistic techniques are used extensively in this process. The result is an ensemble of reservoir simulation models consistent with all subsurface information.

Bio:
Michael E. Glinsky received a B.S. degree in physics from Case Western Reserve University in 1983 and a Ph.D. degree in physics from the University of California, San Diego in 1991. His doctoral research on magnetized pure electron plasmas was recognized by the American Physical Society as the outstanding thesis in the United States (1993 Simon Ramo Award). Before enrolling in graduate school as a National Science Foundation Graduate Fellow, he worked as a geophysicist for Shell Oil Company. After graduate school, he worked as a Department of Energy Distinguished Postdoctoral Research Fellow at Lawrence Livermore National Laboratory for 5 years. More recently he worked for three years at the Shell E&P Technology Co. doing research on Bayesian AVO and 4D inversion. After being the Section Leader of Quantitative Interpretation for BHP Billiton Petroleum, he moved into the BHP Billiton corporate centre where he was Manager, Resource R&D. Currently, he is CEO Science Leader at CSIRO, and an Adjunct Professor of Physics at University of Western Australia. He has published over 25 papers in the refereed scientific literature on subjects as varied as plasma physics, signal processing for oil exploration, x-ray diagnostics, application of exterior calculus to theoretical mechanics, and laser biological tissue interactions. He received the 2004 CSIRO Medal for Research Achievement for his research on petroleum reservoir characterization.
