The Cadomin Formation in the Leland and Ansell areas transitions west to east and stratigraphically upward from poorly-sorted alluvial sands and conglomerates to well-sorted fluvial sands. Reservoir quality, pressures and productivity vary dramatically through the area. The objective of this study is to determine if specific geologically or geophysically mappable features exist that define the higher productivity trends. Results show that variations in productivity seem to be related to the stratigraphy of individual channel units. Although the Basal Channel appears to be a better producer, there is a large variability in production rates and reservoir pressures within this stratigraphic unit. The core analysis also shows there is a large variability in reservoir quality. Mapping of the Basal Channel Unit show it is less constrained by paleotopography than the Conglomerate and follows the depositional trend of the mid and upper Gething. This implies the Basal Channel Unit may actually be part of the Gething Formation.
