Vast quantities of shallow, biogenically derived methane are purported to be trapped under hydrodynamic conditions in various basins throughout the world, with one of the best being the Medicine Hat/ Milk River Gas Fields in SE Alberta and SW Saskatchewan. The term "hydrodynamic condition" in this case refers to a situation where downdip formation water flow occurs under hydrodynamic gradient that is sufficient to counteract the natural updip buoyancy drive causing gas migration. The objective of this study is to determine if hydrodynamic and geologic conditions capable of trapping gas ('Medicine Hat Style' gas trap) may occur in under explored Cretaceous areas of SE Saskatchewan at depths above 500 metres. The Jurassic, Mannville, Viking (Newcastle), Second White Specks (Favel), and Riding Mountain (Pierre Shale) were examined in close detail to have potential reservoir quality sands at desired depths.
