Extended Production Test Planned for Dempsey Gas Well

Sacgasco Limited (ASX:SGC), operator of the Dempsey 1-15 well in the Sacramento Basin,
California advises that initial flow testing of the second deepest zone of gas shows in the
Dempsey 1-15 well is complete.
This zone flowed gas on 12/64 inch choke at a rate of approximately 140 mcf/d with
approximately 150 psi tubing pressure at the time testing concluded. No water was produced.
Following the test, shut in tubing pressure rose to over 6000 psi within 32 hours.
This zone is interpreted to be a significant gas discovery with high pressures, but low
permeability over the zone of perforations. The forward plan is to fracture stimulate this zone
to improve the permeability in the vicinity of the wellbore and achieve greater connectivity
to the zones immediately above and below.
Planning, design and the approval process has commenced. At this stage it is not known
exactly how long the approval process will take. The well is to be placed on production to
sales until the approvals are gained and the well is ready to stimulate.
As previously advised, testing is occurring from the bottom up. This zone of gas must be
adequately assessed before moving up hole to the next zone of interest that exhibited
significant gas shows whilst drilling.
No conclusions should be drawn as to the ultimate flow rates or commerciality of this second
deepest zone until the extended production test and stimulation program and testing are fully
completed.
