BOEPD FROM PARTIAL FRAC
Denver 1700 hours April 5th, 2010
Samson Oil & Gas Limited (ASX: SSN, NYSE AMEX: SSN) provides an operational update on the
Gene #1-22H well.
Gene #1-22H (30.6% working interest)
As previously advised the Gene #1-22 well which is located in Williams County, North Dakota has
been completed as a 5,500 foot horizontal well in the Mississippian Middle Bakken Formation.
Operations to fracture stimulate the well commenced on Wednesday March 31st and Stages 1 and
2 were pumped on Thursday April 1st; this was followed by Stages 3 through 5 which were pumped
Friday and Saturday April 2nd and 3rd. The completion design is for a 16-stage fracture stimulation
so this initial operation amounts to approximately a third of the stimulation program.
Operations were suspended because of the Easter Sunday holiday and the well was flowed back
whilst the service company crews were off site.
The initial flow back results from the first 5 of a planned 16 multi-stage frac were undertaken on
Sunday April 4th. The rate at 0600 hours on Sunday was recorded at 913 mscfd of gas and 960
bopd which is a combined rate of 1,112 boepd.
The flow back continued into Monday April 5th and was recorded at 0800 hours on that day, at 650
mscfd of gas and 840 bopd which is a combined rate of 948 boepd.
The forward plan is to clean out some residual sand that was left in the well after Stage 5 using a
coiled tubing unit. This interim clean out is planned for today, Monday April 5th and the balance of
the frac stages (Stages 6 through 16) will be pumped during the balance of this week. Following
this, the well will be flowed back and the market will receive further advice on the results of the flow
back of the entire well.
