Reservoir Characterization in the West Baram Delta Through Rock Physics Constrained Data Integration

It is well established fact that seismically derived petrophysical properties provide a more complete description of the reservoirs than what could be done through the conventional statistical techniques based on wells and seismic maps. The main objective of present study is to determine which petrophysical parameters control the reservoir quality and how these are related to the elastic properties that control the seismic propagation. Constraining a geological model using seismic derived properties always represents big challenges, mainly because of the uncertainties associated with the seismic properties, and the differences in resolution of the measurements involved in the process. This can only be achieved if a complete and well organized integration between the different disciplines involved is achieved. We present the methodology and results that allowed conditioning the geological model using seismic derived properties in the Siwa field, Sarawak basin, Malaysia.
