Denver 1700 hours August 8 th , Perth 0700 hours August 9 th , 2011 Samson Oil & Gas Limited (ASX: SSN; NYSE AMEX: SSN) advises that the Evergreen Rig 22 has been released from its previous well and is being mobilised to the Defender US33 #2-29H location, and will then be deployed at three additional Samson drilling locations. The initial trucks arrived today and the rig up at Defender US33 #2-29H has commenced, and it is expected that the rig will be ready for its final inspection such that drilling operations should begin late Thursday or Friday this week. Defender US33 #2-29H, Goshen County, Wyoming, Samson 37.5% working interest The Defender US33 #2-29H, is the first Niobrara appraisal well in Samson?s Hawk Springs project. Initially, a vertical pilot well will be drilled to around 7,450? and a conventional core will be cut from the Niobrara Formation. After the orientation of the fractures has been identified from core and FMI logs, the vertical pilot borehole will be plugged back to a kick-off point above the Niobrara. From the kick-off point, the borehole angle will be built until it is horizontal and the bit is positioned within the Niobrara ?B?. Then 7-inch intermediate casing will be set through the curve and the lateral will thereafter be drilled for a distance of approximately 4,300? within the Niobrara ?B?. The well will be completed using a plug and perforation process in 15-stages that is expected to involve the placement of approximately 3,000,000 pounds of proppant into the Niobrara Formation. Sprit of America US34 #1-29, Goshen County, Wyoming, Samson 100% working interest The Defender well will be followed by the Spirit of America US34 #1-29. This well is the first Permian and Pennsylvanian appraisal well within the Hawk Springs project. Preparatory operations, including the well site construction and the setting of the 20 inch surface casing, have been accomplished. The Spirit of America US34 #1-29 will be drilled as an 11,000? vertical test to the Precambrian basement to evaluate multiple conventional targets; in particular, two closed structural traps in the Permian and Pennsylvanian sections. Following the completion of the two Hawk Springs wells, the Evergreen Rig 22 will be mobilised to Montana to drill the initial two wells in the Roosevelt project. Australia II KA6 #1-29H and Gretel 11 KA12 #1-30H, Roosevelt County, Montana, Samson 100% working interest These wells will be the first two appraisal wells in the Roosevelt Project. Both wells will be drilled initially as vertical pilot holes to enable cores to be cut in the Bakken Formation, and then completed as a 15,500? measured depth horizontal wells in the middle member of the Bakken Formation. The wells will then be fracture stimulated. The design of this completion is currently being undertaken but the final design will build on industry results previously achieved in the area.
