The Shell Canada oil sands acreage in Peace River, west-central Alberta, hosts a 7 billion barrel in-place bitumen thermal project, producing from the Cretaceous Bluesky sandstone reservoir. The reservoir comprises tide-dominated delta-plain sands overlain by estuarine sands of poorer reservoir quality. Regions of the field amenable to thermal recovery development techniques were identified with the help of a field-wide static reservoir model.

 

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.
