The Viking Formation is a stratigraphic 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.[2]
Hydrocarbon production
The Viking Formation is composed of fine to coarse grained sandstone with interbeds of conglomerate and cherty conglomeratic sandstone. [1] 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.[3] Gas reserves totaled 277.9 million e³m³ (or 227,900 million m³), with 103.4 million e³m³ (or 103,400 million m³already produced.[4]
Hydraulic fracturing in Canada
Massive hydraulic fracturing has been widely used in Alberta since the late 1970s.[5]: 1044 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.
