Similar to the Cardium, the Devonian Duvernay formation is part of the Western Canadian Sedimentary Basin group. Duvernay is characterized by an average porosity of 6.5%; an average permeability of 394 nD; and an average of 4.5% TOC.
The Duvernay Shales have been credited as the source rock for many of the large Devonian oil and gas pools in Alberta, including the most famous, The Leduc Field discovered in 1947.
The Duvernay compares favorably to other North American Shale plays, showing good porosity, overall thickness, organic content and is overpressured - all of which are key to a successful play
An estimated 7,500 square miles is thought to be in the liquids-rich gas window where reported liquid recoveries range from 75 to 150 bbl/MMcf Targeted for its shale gas condensate, the Duvernay is a popular target amongst Canadian exploration and production companies.
