North American Bakken Oil Field Play - covering parts of Montana, North Dakota, and Saskatchewan.

The USGS estimate of 3.0 to 4.3 billion barrels of undiscovered, technically recoverable oil in the Bakken Formation, and a mean estimate of 3.65 billion barrels, is an estimate of what industry may recover if the entire area of prospective Bakken Formation is produced using current technology. The current USGS mean estimate is a 25-fold increase over the previous USGS estimate, in 1995, of 151 million barrels of undiscovered technically recoverable oil in the Bakken Formation. As of August 2009, cumulative oil production from the Bakken Formation totaled about 190 million barrels (up from 164 million barrels in March 2009, 149 million barrels in December 2008 and 135 million barrels in September 2008).

Woodford Shale Emerging as a Leading Domestic Oil and Gas Play

Recent Commentary: Patrick J. Murphy, of Murphy Analytics LLC

Full article: http://www.investorideas.com/CO/AAPH/news/2011/03301.asp

As noted by American Petro-Hunter (OTCBB: AAPH) CEO Robert McIntosh in the Company's January 2011 Corporate Newsletter, production in the Woodford Shale has skyrocketed over the last few years. CEO McIntosh and others have referred to the Woodford as a world class oil and gas target, an assertion that seems justified given that the Woodford Shale now ranks second domestically in gas production and fifth in oil production. Following is data and commentary related to the operations and outlook for some of the Woodford Shale's most active players.

Devon Energy (NYSE: DVN): In a presentation1 at the Oppenheimer Unconventional Oil and Gas Conference, DVN noted that its Woodford assets benefit from a low cost of entry at approximately $2,200 per acre and a low average royalty burden at approximately 21%. The Company also notes that it recently completed construction of a gas processing plant, and after drilling 87 wells in 2010, DVN plans to drill over 200 wells in the Cana-Woodford Shale in 2011. Discussing the Company's Q4 20102 earnings, CFO and Executive Vice President Jeffrey Agosta commented on DVN's interest in the shale:

"Moving to the Cana-Woodford Shale in Western Oklahoma, we continue to add to our acreage position during the fourth quarter and now have approximately 243,000 net acres. Devon is currently operating 23 out of the 39 rigs running play-wide."

Marathon Oil (NYSE: MRO): At a recent Credit Suisse conference, MRO noted its interest3 in the Anadarko Woodford Shale play, with 3 rigs operating currently and 8 planned by the end of 2011. The company also observed that returns there are among the highest of domestic resource plays, and while exiting 2010 at approximately 1,500 BOED, MRO estimates that, by 2015, it could reach a peak rate of 30,000 BOED. In the Company's Q4 20104 conference call, Executive Vice President David Roberts noted that MRO plans to more than double its acreage in the area:

"Marathon also holds 86,000 acres in the Anadarko Woodford area, an area where we have operated for decades, and we have line in sight on new opportunity to increase that position to over 100,000 acres shortly. Importantly, we will have eight rigs in the play by 2011 by the end of this year."
