Delineating a Sand Reservoir Using 3C-3D Seismic Data, Horizontal Well Logs, and VSP

A20 DELINEATING A SAND RESERVOIR USING 3C- 3D SEISMIC DATA HORIZONTAL WELL LOGS AND VSP Abstract This paper uses 3C-3D seismic data horizontal and vertical well logs and VSP to delineate a sandstone reservoir. The 3C-3D surface seismic data was acquired over Husky Energy’s Ross Lake oilfield in south-western Saskatchewan. In previous work a Vp/Vs map between two marker horizons (the IHACM and RushLake) was calculated by combining PP and PS travel time thickness maps. In this paper the impedance inversions are performed on the poststack PP and PS data. By dividing the average of the inverted P-impedance over a
