Integrated geological and geophysical analysis of a heavy-oil reservoir at Pikes Peak, Saskatchewan.

摘要

Various seismic techniques can be used for monitoring zones of steam injection in heavy-oil recovery. In this integrated case study, post-stack interpretation based analysis techniques are used to delineate steamed and heated reservoir zones at Husky Energy's Pikes Peak heavy-oil field in Saskatchewan. Four methods are compared including reflectivity differencing, impedance differencing, P-wave traveltime ratios, and an isochron method for examining VP/V S. All methods show promise and consistency for delineating areas of steam injection and temperature increase in the reservoir away from well control.; The integration of well and seismic data reveals methods to further understand the reservoir. The percentage of sand in the reservoir interval is estimated using VP/VS. The reservoir trap and bottom-water presence are interpreted using isochron measurements of a deeper interval.; A single multicomponent seismic survey is a powerful tool for reservoir surveillance and interpretation at any stage of field development.
