Samson Oil & Gas Advises the Gene #1-22H Well Ready to Frac

Gene #1-22H

(30.6% working interest)

Samson Oil & Gas Limited (ASX: SSN)(NYSE AMEX: SSN) advises that the

Nabors 668 rig was released as scheduled on February 16th

after successfully running 5,500 feet of production liner, thus readying

the well for fracture stimulation and production. The liner was run

incident free in just 8.5 hours, completing a very successful drilling

operation that was ahead of time and under budget.

The Operator advises that this well is expected to be fracture

stimulated in mid to late March. Further advice is that the Operator is

expecting to maintain the contract on the Nabors 668 drilling rig

through the balance of the calendar year, alternating between the North

Stockyard Oilfield and other wells in the immediate area. Samson

therefore expects several additional wells will be drilled during 2010

in the six 640 acre sections in which Samson has equity.

The production liner run at Gene #1 22H is the same type as is generally

used by the industry in the Williston Basin. The liner has external

packers that swell and seal the liner through the absorption of drilling

fluids. This eliminates the need to cement the liner, which would fill

the natural fractures in the target formation and inhibit hydrocarbon


The external packer system has been largely responsible for the recent

success of the Bakken Formation and, more recently, in the development

of the “perf and plug” technique that has established record production

levels within the Formation

Once the production liner is set, and the drilling rig released, a

perforation gun equipped with a plug is pumped into the liner on a wire

line. The plug is electrically set and seals the previous fracture

stimulated stage then four single perforations are sequentially fired

along a 200-foot section between two of the external packers (One

stage). The proppant is then pumped and a fracture is initiated and

rather than propagating a single fracture "swarm" there is the potential

to initiate four "swarms" through each of the perforations. This is

achieved because the weakest rock breaks down first and as that frac

grows the friction losses increase and diverts to the next weakest rock

and then the third and fourth.

When all of the sixteen 340-foot stages have been fracture stimulated,

the plugs separating the stages are reamed out and the well is placed in


The Gene #1-22H is the second well in which Samson has an interest

within the North Stockyard field. The previously drilled Leonard well

established the productivity of the Bakken in this field. However

significant improvements in completion technology have occurred in the

intervening two years that are now being applied to the Gene well,

including the “plug and perf” method described above and the utilization

of higher strength proppants. Samson currently expects that the Gene

#1-22H and other wells in the North Stockyard field will add significant

oil production to its existing producing assets.

Samson’s Ordinary Shares are traded on the Australian Securities

Exchange under the symbol "SSN". Samson's American Depository Shares

(ADSs) are traded on the New York Stock Exchange AMEX under the symbol

"SSN". Each ADS represents 20 fully paid Ordinary Shares of Samson.

Samson has a total of 1,294 million ordinary shares issued and

outstanding, which would be the equivalent of 64.7 million ADSs.

Accordingly, based on the NYSE AMEX closing price of US$0.48 per ADS on

February 16th 2010 the company has a current market

capitalization of approximately US$31.06 million. Correspondingly, based

on the ASX closing price of A$0.028 on February 16th, 2010,

the company has a current market capitalization of A$36.2 million.
