Boundary-Element Dynamic Reservoir Simulator to Integrate Transient Pressure and Rate Data with the Geo-Seismic Information

Summary A new semi-analytical reservoir simulator has been used to integrate pressure and rate transient analysis with the geo-seismic information. The simulator is based on the boundary element method for accurate simulation of fluid flow in reservoirs, without the need for numerical areal gridding. The user draws complex reservoir regions on a seismic structural map and the tool simulates well pressure analytically in a few seconds and compares it with the pressure measured by downhole pressure gauges in the same wells. This helps test different reservoir heterogeneities, fault transmissibility and connectivity in an instant, integrating pressure transient analysis with the geo-seismic information.
