In 2014, we grew our proved plus probable reserves by 7%, to 429 MMBOE.
This represented a 175% production replacement, net of acquisitions and divestments.
Reserves are presented on a company interest basis at year end, in accordance with National Instrument 51-101, based on evaluations from third party reserves engineers.
Our "best estimate" of contingent resources is 449 MMBOE. This estimate includes the Marcellus, the Bakken and Three Forks, a portion of our Waterfloods and our Wilrich assets.
We believe there could be further upside associated with the Duvernay.
At our production rate for 2015, this resource estimate would provide approximately 13 years of organic reserve replacement.
