This model was assembled by integrating
2-D and 3-D seismic data, well-logs and detailed core descriptions.
Electrofacies, reservoir quality and stratigraphic architecture were identified
and mapped. Reservoir quality plays an important role in directing steam into
the formation and draining bitumen back to the well,
hence its 3-D distribution was captured in the model.
Net pay, bottom water, top gas isopach
maps and 3-D reservoir property models helped in identifying thermally amenable
regions of the field. These areas were devoid of intraformational gas and water
thief zones.
