NORTH STOCKYARD PROJECT
Everett #1-15H (31% working interest)
Samson Oil & Gas Limited (ASX: SSN, NYSE AMEX: SSN) advises that the Everett #1-15H well is
today drilling ahead in the lateral at a measured depth of 13,107 feet. Previous operations saw the
7 inch casing cemented at a measured depth of 11,231 feet. This depth was 112 feet shorter than
planned but should not compromise the well because this section will be cased when the 4 inch
liner is installed.
The lateral is being drilled whilst observing characteristic oil and gas shows. The Everett #1-15H
well is located in Township 154N, Range 99W, Section 15 in Williams County, North Dakota. The
Everett #1-15H well is Samson?s sixth Bakken well in the North Stockyard Field.

Earl #1-13H (32% working interest)
Significant progress has been made in recovering the parted tubing string which was being used to
drill the isolation plugs in the Earl #1-13H well. The remaining tubing and drilling assembly consists
of a 1,200 feet section and the top of this fish has been conditioned such that it should be able to
be extracted in the next 24 hours.
The Earl #1-13H well is located in Township 154N, Range 99W, Section 13 in Williams County,
North Dakota.

HAWKSPRINGS PROJECT
Defender US 33 #2-29H (37.5% working interest post farmout)
The location of the Defender well, which will be the first of the Niobrara horizontals, has been
agreed and is expected to spud in mid-July. This well is planned as a 4,000 foot lateral in the
Niobrara ?B? zone and will be fully funded by our farminee. The direction of the lateral will be
determined only after an orientated core is recovered from the vertical pilot hole. Examination of
the core and its fracture orientation will be used to finalize the preferred direction of the lateral.
The Defender US 33 #2-29H well is located in Township 25N, Range 63W, Section 29 in Goshen
County, WY.
