The Stettler field is in the central plains of Alberta, Canada, approximately 100 miles northeast of Calgary. The field was found by detailed seismograph and structural core drilling. The producing reservoir was found in May, 1949, in two reefoid zones of Upper Devonian age. As of December 15, 1950, there are 23 producing wells in the field, eight of which are producing from the D3 zone. The field has not been delineated to date, but extends 4 miles north-south, and 1½ miles east-west. Lower Cretaceous gas and oil have been found 5 miles west of the Devonian field, and a second pool is located 3½ miles northeast. Only beds of Cretaceous, Mississippian, and Devonian age have been drilled in the field.

The Devonian producing zones are tentatively correlated with the D2 and D3 reefoid zones of the Leduc area. The average depth to the porous D2 pay zone is 5,178 feet, and to the D3 pay zone 5,350 feet. The gravity of the D2 oil is 30°-31° A.P.I., and the D3 oil is 27°-28° A.P.I.
