The Viking Formation is a stratigraphical unit of Cretaceous age in the Western Canadian Sedimentary Basin.
It takes the name from the town of Viking, Alberta, and was first described in the Viking-Kinsella oil field by Dowling in 1919.
The Viking Formation is composed of fine to coarse grained sandstone with interbeds of conglomerate and cherty conglomeratic sandstone. Nodular phosphorite, coal fragments and concretionary siderite occur in the coarse beds.
Oil is produced from the Viking Formation in eastern and central Alberta as well as in west-central Saskatchewan.
The Viking Formation had an initial established recoverable oil reserve of 88.7 million m³, with 66.8 million m³ already produced as of 2008.Gas reserves totaled 277.9 million e³m³ (or 227,900 million m³), with 103.4 million e³m³ (or 103,400 million m³already produced.
Massive hydraulic fracturing has been widely used in Alberta since the late 1970s. The method is currently used in development of the Cardium, Duvernay, Montney and Viking formations in Alberta, Bakken formation in Saskatchewan, Montney and Horn River formations in British Columbia.
