Samson Oil & Gas Limited (ASX: SSN) (NYSE MKT: SSN) provides an operational advisory. HAWK SPRINGS PROJECT, GOSHEN COUNTY, WYOMING Spirit of America US34 #2-29, (SSN 100% WI) Fracture stimulation operations have been completed in the SOA #2 after pumping a total volume of 57,900 lbs of proppant into Stage 3, within the Permian aged Cassa Formation. The well is currently shut-in and flow back operations are due to commence this evening (MST US time zone). Stage 2 was by-passed for the time being because it was below the bridge plug that was previously placed in the well bore and will be the subject of a further stimulation job, subject to the results obtained from the stimulated zone. It is expected that a coil tubing unit will be used to ensure that the well bore is clean of frac sand prior to being placed on a jet pump.
