Multicomponent seismic characterization and monitoring of the CO₂ flood at Weyburn Field, Saskatchewan

High-resolution, time-lapse (4D), multicomponent (9C) seismic monitoring of a tertiary oil recovery project is being conducted by the Reservoir Characterization Project of the Colorado School of Mines. The project involves a miscible CO₂ flood in a thin (30 m) carbonate reservoir at 1450 m depth in Weyburn Field, Saskatchewan. Multicomponent time-lapse seismic images illustrate the influence of fracture zones on the flood. These fracture zones are very important to characterize and monitor in order to manage the flood successfully and to achieve the desired improved recovery efficiency. The monitoring project offers insights into the future of dynamic reservoir characterization...
