Samson, Devon, Enter JV in Baxter Shale Operations

Samson Oil & Gas Limited ("Samson") has executed an Exploration Agreement with Devon Energy Production Company ("Devon"). The agreement 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 will operate the seismic acquisition and any subsequent exploratory program. Samson anticipates that the seismic acquisition will be undertaken in the summer of 2008. 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.

The acquisition of 3D seismic is a necessary first step in the evaluation process such that naturally occurring fractures systems can be identified and evaluation drilling. This appears to be one of several technical keys to the successful flow rates seen to date in the Vermillion region. Samson's agreement with Devon Energy would appear to complement their existing lease holding which is shown on the attached map. This map shows both Samson's acreage (in yellow) and Devon's (in green).
