Rubicon Unit Formed to Explore the Baxter Shale

The formation of the Rubicon Unit affects no change to the previous commercial arrangement entered into between Devon and Samson, which in summary allows Devon to earn up to 50% in the Samson leases whilst Samson retains the balance.

To maintain the Rubicon Unit a drilling program has to commence within a specified time frame and to this end Devon has proposed a well to be drilled in Section 28 which is immediately adjacent to the Samson leases. This well in which Samson has no equity (or cost) is proposed to be drilled to a depth of 16,000 feet and will evaluate the Baxter Shale. This well could be used to calibrate any 3D seismic survey which may be acquired and which could guide the exploitation effort through the use of future wells. It is expected that the Devon Rubicon 16-28-1 well will commence drilling during July 2008. A 3D seismic survey has been proposed and awaits the necessary regulatory approvals.

As previously reported the Exploration Agreement with Devon covers Samson’s 6,400 acre holding in the western flank of the Vermillion Basin in Sweetwater County, Wyoming. This area contains a 3,500 foot section of Baxter Shale which was drilled in the 1970’s and recovered a significant flow of gas from an unstimulated Baxter Shale. Since that time there has been significant development of the Baxter Shale in the Vermillion region 40 miles east of Samson’s acreage, where our competitors have expended significant funds that have resulted in flows of up to 9 mmcfpd from the Baxter Shale.

The Exploration Agreement envisages that a 3D seismic grid will be acquired in an effort to define an exploratory program. Devon would operate the seismic acquisition and any subsequent exploratory program. Samson will hold a 50% interest in the leasehold block unless Samson permits a third party to complete the second farm-in well in the Greens Canyon area and earn an 18% equity stake in Samson’s leases. In that circumstance, Samson would retain a 32% equity interest in these leases.
