SAMSON OIL & GAS OPERATIONAL ADVISORY
Denver 1700 hours January 12th, 2011, Perth 0700 hours January 13th, 2011
Samson Oil & Gas Limited (ASX: SSN; NYSE AMEX: SSN) advises on the following field
operations:
ROOSEVELT PROJECT
Gretel II 12KA 3, Roosevelt County, MT (SSN 100%, subject to a 33.34% back-in option)
The DHS Rig 1 is rigged up on the Gretel II well site and is ready to commence drilling operations
from the 9 5/8 inch casing shoe which had previously been set at 1,701 feet. A repair has been
necessary to the top drive unit and this is expected to be completed within the next 24 to 48 hours
and drilling operations are expected to start shortly thereafter.
The Gretel II 12 KA 3 well is Samson’s second Bakken well in the Roosevelt Project.
Australia II 12KA 6, Roosevelt County, MT (SSN 100%, subject to a 33.34% back-in option)
As previously advised the Australia II well has been successfully drilled to a total measured depth
of 14,972 feet.
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 has been set such that the well is made safe.
Contract negotiations are being undertaken with two mainstream pressure pumping companies
such that this well can be fracture stimulated in the first quarter.
HAWK SPRINGS PROJECT
Defender US33 #2-29H, Goshen County, WY (SSN 37.5% carried working interest)
The Defender US33 #2-29H work over rig is due to arrive on location on Friday January 13th and
will commence a pump change out. This operation will be completed over the weekend and the
well is expected to be pumping with the replaced pump Monday January 16th. As previously
advised the pump has not been operating efficiently and therefore the new pump is expected to
establish a rate that is diagnostic.
The Defender US33 #2-29H is the first Niobrara appraisal well in Samson’s Hawk Springs project
