SAMSON OIL & GAS OPERATIONAL ADVISORY
Denver 1700 hours July 16th, 2012, Perth 0700 hours July 17th, 2012
Samson Oil & Gas Limited (ASX: SSN; NYSE AMEX: SSN) provides operational advice.
HAWK SPRINGS PROJECT, GOSHEN COUNTY, WYOMING
Spirit of America US34 #2-29, (SSN 100% WI)
After preparing the well for the fracture stimulation treatment, Stage 1 pumping operations (at a depth of around 10,000 feet) commenced on late Thursday, July 12th. The job went as planned with the placement of 47,560 pounds of proppant. The well was then flowed back for approximately 14 hours with the recovery of 27% of the fluid pumped.
The potential problems with moving the bridge plug during the preparations to pump Stage 2 disclosed in the July 12th Advisory were in fact encountered, with the bridge plug and packer becoming stuck by frac sand, which has required a recovery operation. This recovery operation is expected to conclude today. Accordingly, stimulation operations have been temporarily suspended until the well can be prepared to effectively stimulate Stage 2. We expect stimulation operations to continue next week.
If an adequate rate is obtained from this frac, then there would be many opportunities to pursue, both within the SOA prospect itself (such as drilling the Clipper location immediately adjacent, and subsequently the twenty-four, 40-acre spaced wells within this prospect) and in the 24 seismically defined prospects within the project area. These prospects have substantially identical seismic properties to the SOA #2 prospect, which has now been proved to be generated by porosity development within the Permian section. Some of these prospects are located at substantially shallower depths, and could provide a consequential improvement in reservoir quality.
