Abstract

The Spearfish, or more proper(v, Lower Amaranth Formation in southwest Manitoba is a low permeability sandstone reservoir con- taining low GOR light oil. Wells drilled into this formation are generally not capable of commercial production until after a hydraulic fracturing stimulation. Factors such as an underlying water zone, along with an unconfined producing interval, have resulted in numerous hydraulically fractured Lower Amaranth wells producing water rather than oil, limiting potential field de- velopment.
