Alberta Bakken Pool

Alberta Bakken Schematic Cross Section

Granite’s oil production comes from the Mississippian-aged Upper Bakken siltstone, which lies at a depth of 1,250-1,300 metres and has a thickness of 2-14 metres.

The Upper Bakken siltstone has very low clay content, average porosity of 9-12 percent and average permeability of approximately 5 millidarcies, less "tight" than many unconventional reservoirs. The eastern pool area is up to 14 metres thick, while the largely underexplored western land base, is thinner with more unconventional characteristics.
