Samson Oil & Gas Advisory on Gary #1-24H Frac Operations

Gary #1-24H (37% Working Interest)

DENVER & PERTH, Australia--(BUSINESS WIRE)--Samson Oil & Gas Limited (ASX: SSN) (NYSE AMEX: SSN) advises that the first fracture stimulation stage pumped 150,000 pounds of proppant into the Gary #1-24H well according to the planned program, however in preparing for the second stage the isolation plug set prematurely above its planned setting depth. It is now required that the second stage isolation plug be drilled out using a coiled tubing unit before continuing the remainder of the fracture stimulation job. This operation is expected to be undertaken later this week and the stimulation program should re-commence on or about September 13th. We do not anticipate any reduction in well performance.
