This study determines the relationship between structural trends within the Nisku Formation's Cynthia Member and hrydrodynamic and hydrochemical patterns. A regional hydrodynamic and hydrochemical overview of the Cynthia Member is provided. This study integrates the hydrodynamic-hydrochemical findings with existing knowledge of the local geology and outlines the extent of hydraulic continuity within and between individual Cynthia margin to basin transitions. Furthermore, and outline of the distribution and extent of individual gas/oil pools and fluid contacts is shown.
