As part of a DOE Class II Oil project, a wide variety of data were acquired in a Permian Basin oil field. This included core, log and petrophysical data, as well as interwell borehole seismic data. Borehole seismic data was acquired to provide baseline surveys for future CO2 monitoring, but also to investigate its use for high resolution reservoir characterization. A method was developed to derive detailed porosity and permeability maps between wells using the log, core, and interwell seismic data together with certain petrophysical relationships. The resulting interwell porosity and permeability maps provide a natural basis for extracting statistics, such as variograms, needed for geostatistical reservoir modeling and simulation. This procedure provides an important new alternative for obtaining spatial statistics needed for geostatistical reservoir studies.
