Samson Oil & Gas operational advisory

Source: Samson Oil & Gas Limited

Samson Oil & Gas Limited (ASX: SSN.AX) (NYSE AMEX: SSN) advises on the following field operations:


Australia II 12KA 6, Roosevelt County, MT (SSN 100%, subject to a 33.34% back-in option)

The Australia II well has been successfully drilled to a total measured depth of 14,972 feet. The horizontal lateral remained “in zone” for the entire lateral length and returned excellent oil and gas shows. The rock samples were largely consistent, exhibiting a lithology associated with the vertical cored interval that was the porous and permeable middle Bakken zone.

The rate of penetration of the lateral was excellent and confirms that the lateral was maintained in the reservoir facies. Some operational interruptions, such as two failures of the MWD tools, were experienced; however, these types of failures are not unusual.

The 4 ½ liner equipped with 15 external casing packers was then run to total depth and set in the 7 inch casing shoe. A retrievable bridge plug is currently being set such that the well is made safe. It is expected that the drilling rig will be released to Samson’s Gretel II location in the next 48 hours.

Contract negotiations are being undertaken with a mainstream pressure pumping company such that this well would have a frac date of mid-February.


Defender US33 #2-29H, Goshen County, WY (SSN 37.5% carried working interest)

The Defender US33 #2-29H well continues to be pumped but the pump rate suggests that the pump valves may have been damaged, so this pump will be replaced in the near future. Approximately 40% of the fracture stimulation fluid has been recovered to date and it remains too early to establish an oil production rate.

The Defender US33 #2-29H is the first Niobrara appraisal well in Samson’s Hawk Springs project and is being fully carried by Samson’s farmin partner.

Spirit of America US34 #1-29, Goshen County, WY (SSN 100% working interest)

The Spirit of America well has been fracture stimulated with 92,000 pounds of proppant in the Cretaceous Muddy Formation (J-Sand). The flow back to date has resulted in only trace amounts of gas being produced (no oil or formation fluids) due to the permeability of the reservoir being too tight. We will continue to flow the well over the next few weeks to fully recover the frack fluid and further evaluate the reservoir.


Everett #1-15H, Williams County, ND (SSN 26% working interest)

Fracture stimulation operations have been completed to Stage 11 of 20 planned stages. However, Stage 11 was “screened out” and the sand in the well bore was not able to be flowed back. A coiled tubing unit is required to remove the sand in order to permit the remaining stages to be completed. Because of the holiday period, a coiled tubing unit was not immediately available but one will be mobilized early in 2012 to complete the stimulation of this well.

The Everett #1-15H well is Samson’s sixth Bakken well in the North Stockyard Field.

Samson’s Ordinary Shares are traded on the Australian Securities Exchange under the symbol "SSN".

Samson has a total of 1,996 million ordinary shares issued and outstanding (including 246 million options exercisable at AUD 1.5 cents), which would be the equivalent of 99.8 million ADSs. Accordingly, based on the NYSE AMEX closing price of US$2.18 per ADS on December 29, 2011 the Company has a current market capitalization of approximately US$212.6 million. Correspondingly, based on the ASX closing price of A$0.105 on December 29, 2011, the Company has a current market capitalization of A$205.4 million. The options have been valued at their closing price of A$0.088 on December 29, 2011 and translated to US$ at the current exchange of 1.01 for purposes of inclusion in the US$ market capitalization calculation.
