operational advisory

DENVER & PERTH, Australia, Jun 04, 2012 (BUSINESS WIRE) -- Samson Oil & Gas Limited (asx:SSN) /quotes/zigman/478556/quotes/nls/ssn SSN -3.70% provides operational advice on its Hawk Springs and Roosevelt Projects.

HAWK SPRINGS PROJECT, GOSHEN COUNTY, WYOMING

Spirit of America US34 #2-29, (SSN 100% WI)

The Spirit of America #2 well was drilled into granitic basement at a total depth of 10,634 feet. The well was logged and a production liner is in the process of being run to around 10,100 feet and cemented. Quantitative log analysis is being undertaken which will be used to finalise a cased hole testing program. The forward plan for the drilling rig is to run the liner, cement it and then run production tubing and a packer such that the balance of the production test can be conducted using wireline equipment.

ROOSEVELT PROJECT, ROOSEVELT COUNTY, MONTANA

Australia II 12KA 6, #1-29H, (SSN 100%, subject to a 33.34% back-in right)

The well is currently pumping and has been on stream for 8 days. The oil rate has ranged from 244 BOPD to 79 BOPD with an average rate of 147 BOPD. The well has experienced a decline in oil rate and oil cut over this period. This is contrary to the early production history of offsetting Bakken wells in the region, but production may improve due to the requirement to reduce the hydrostatic pressure on the reservoir and to reduce frac and kill fluid saturation in the near wellbore.

Gretel II 12KA 3 #1-30H, (SSN 100%, subject to a 33.34% backin right)

The production facilities have been installed and the well is expected to be put on pump this week.
