Mmboe

Anschutz Exploration Corp. has exited the Bakken Shale play after closing the sale of its remaining operated and nonoperated oil and gas producing properties in the Williston Basin, including undeveloped acreage, to an undisclosed Canadian oil company for $115 million. The deal comes less than a year after the company sold 180,000 net acres to Oxy USA in December 2010 for $1.4 billion.

The bet made by Pioneer Natural Resources Co. to focus on U.S. exploration appears to paid off — proved reserves grew by 128 MMboe last year, and the producer replaced 357% of production primarily in its core onshore areas and through several key U.S. acquisitions.

Following an appraisal of its deepwater Droshky prospect in the Gulf of Mexico, Marathon Oil Corp. estimates the discovery holds mean recoverable resource of 80-90 MMboe. The Droshky discovery is located in 2,900 feet of water on Green Canyon Block 244, about 137 miles south-southwest of Venice, LA. The appraisal process consisted of drilling a down dip sidetrack well and a lateral sidetrack well. The wells are about two miles south of the Troika Field Production System. The initial well was drilled to a total depth of 21,190 feet and encountered 250 feet of net oil pay. The down dip appraisal sidetrack encountered more than 600 feet of net oil pay, while the lateral sidetrack encountered 300 feet of net oil pay. All pay intervals are Upper Miocene in age. Marathon expects to produce the field via subsea completions through the Troika system and Bullwinkle Platform, with terms already in place. The timing of initial production will be dependent upon delivery of key equipment (i.e., drilling rig and subsea equipment) and regulatory approvals, but could be as early as 2010. Marathon holds a 100% working interest in the Droshky prospect and a 50% working interest in the Troika unit.

Devon Energy estimated that first quarter oil and gas production will fall 2 MMBoe short of its previous estimate. It also revised its U.S. gas and Canadian oil price realizations.
