This is a hydrodynamic analysis of the Pekisko Formation from the Sylvan Lake area, though the Garrington area south to the Twining Area (T28-38, R 23W4-07W5). The primary objectives of this study were to examine the hydrodynamic break west of the Sylvan Lake subcrop play and determine whether it may be associated with a continuous hydrocarbon accumulation, as well as determine whether a pressure break exists between Twining subcrop play and the downdip gas located in the Swalwell/Entice area.
