This study focuses on quantifying the trapping potential in the Nisku Formation at a regional level, and at a detailed level where features have been identified by 3D seismic. Direction and magnitude of the hydraulic gradient within the Nisku Formation and the potential for effective flow are established. This study determines the significance of regional potentiometric surface variations as they relate to the known geology of the area. The oil entrapment potential is calculated through impelling force vector analysis. This study also predicts the expected dip of oil/water interface under observed hydrodynamic conditions and minimum structural closure required for oil entrapment.
