This case history describes seismic monitoring efforts at Pikes Peak Field, a prolific heavy-oil field (production exceeding 42 million barrels) just east of the Alberta-Saskatchewan border that has been operated by Husky Energy since 1981.

The Lower Cretaceous Waseca Formation, about 450 m below surface, is the producing reservoir.
