Most NW‐SE trending, offshore, tide‐generated reservoir sandstones in the Lower Cretaceous Viking Formation of Alberta and Saskatchewan produce oil and/or gas from their NE flanks. This is because stronger tidal currents sorted and shifted finer sediments from the NE to the SW in the direction of sandbody migration. Thus, the NE flanks are older, thinner, coarser and better sorted with good reservoir characteristics. Post‐despositional tilting, however, provided optimal conditions for oil and gas entrapment. This pattern of hydrocarbon occurrence may be more profitable if applied to the exploration and development of oil and gas in the less‐developed sand units.
