Reservoir geometry influenced by high-frequency forced regressions within an overall transgression: Caroline and Garrington fields, Viking Formation (Lower Cretaceous), Alberta

584 well logs and 139 cores have been used to establish a two-part stratigraphy for the Viking Formation in the area of the Caroline and Garrington reservoirs, Alberta. The lower part consists of a northeastward-prograding coastal succession of offshore and shoreface storm deposits, capped in places by nonmarine facies. The upper stratigraphic unit consists of marine black shales with five tongues of coarse sandstone and conglomerate, each 1-3 …
