Dempsey 1-15 well second zone to be placed on production pending
stimulation
Empyrean Energy (EME: AIM), the oil and gas development company
with interests in China, Indonesia and the United States, is
pleased to announce that it has been informed by Sacgasco Limited
(ASX: SGC) ("Sacgasco"), the operator of the Dempsey 1-15 well in
the Sacramento Basin, onshore California, 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 150psi tubing pressure
at the time testing concluded. No water was produced. Following the
test, shut in tubing pressure rose to over 6000psi 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 stimulation
production test and stimulation program and testing are fully
completed.
Empyrean CEO Tom Kelly commented, "It is very early days in the
testing of the Dempsey 1-15 well, and whilst the bottom two zones
have both flowed clean dry gas with very high down hole pressures,
both zones exhibit tight permeability. The pressure and potential
extent of gas reservoir are significant and every effort is being
made to use industry best practices in order to see if we can
stimulate the second deepest zone to achieve a much better flow
rate before moving up hole to test the next zones of interest."
This announcement has been reviewed by Empyrean's Technical
Director, Mr Frank Brophy BSc (Hons), who has over 50 years
experience as a petroleum geologist.

Notes to Editors
About Empyrean Energy Plc (LON: EME)
Empyrean is a London AIM listed oil and gas explorer with three
potentially high impact new projects. Empyrean has a 1800km2
offshore oil permit located in the Pearl River Mouth Basin, China
where it has completed 3D seismic in Q3, 2017 to further mature two
large oil prospects, Jade and Topaz. Processing and interpretation
is underway and preliminary internal interpretation of the raw
seismic data has confirmed the structural validity of the Jade and
Topaz prospects and also identified a third significant target
named Pearl, which is located north of Topaz. The permit is
directly South East of the billion barrel+ Liuhua Oil Field
operated by CNOOC and two recent discoveries to the permits West
and South further enhance the merit of Jade and Topaz. Empyrean is
operator and holds 100% of the exploration rights through to
commercial discovery where CNOOC have a back-in right to 51%.
Empyrean also has a 10% interest in West Natuna Exploration
Limited that holds 100% of the Duyung PSC in offshore Indonesia and
is targeting the Mako Shallow Gas Discovery that has an
independently verified 2C and 3C gas resource of between 430-650
Bcf recoverable gas. Successful testing operations were recently
completed at the Mako South-1 Well with 10.9 million cubic feet of
gas flow and better than expected reservoir quality and multi Darcy
permeability. The operator is currently analysing data with a view
to providing a development plan.
Empyrean also has a joint venture with ASX listed Sacgasco
Limited on a suite of projects in the Sacramento Basin, onshore
California, USA. The package includes two mature, multi-Tcf gas
prospects, 'Dempsey' and 'Alvares', and an Area of Mutual Interest
(the "Dempsey Trend AMI") that includes at least three already
identified, large Dempsey-style follow up prospects. Dempsey is a
large structure mapped with 3D seismic and interpreted by Sacgasco
to have the potential to hold a prospective resource of over 1 Tcf
of gas in up to seven stacked target reservoirs. The joint venture
has completed drilling of a 2,970 metre (9,747 fee) combined
appraisal and exploration well; Dempsey 1-15, to evaluate this
prospect. Wireline logs confirmed numerous zones for production
testing.
Aside from compelling technical merit, the Dempsey-1 well
location sits next to existing gas metering and surface
infrastructure that is owned by the joint venture. This will allow
for any gas discovery to be tested and connected into the local
pipeline at relatively low cost and in an accelerated timeframe.
This early potential for short-term cash flow in the event of a
commercial discovery would be significant for the joint venture and
for the state of California where gas demand is high and
approximately 90% of consumption is imported from other states. Gas
produced in the Sacramento Basin currently prices at a 10-15%
premium to Henry
Hub Gas Prices. The joint venture is currently testing the Dempsey Prospect.
Alvares is a large structure mapped with 2D seismic and
interpreted by Sacgasco to hold prospective resources of over 2 Tcf
estimated potential recoverable gas. A well drilled by American
Hunter Exploration Limited in 1982 for deeper oil intersected
5,000ft of gas shows. No valid flow test was conducted due to
equipment limitations and the deeper oil target failing. However
minor gas flows to surface were recorded even with these
limitations. The possibility of using the existing well bore to
sidetrack and get a valid flow test, thus reducing costs will be
examined.
The Dempsey Trend AMI is an Area of Mutual Interest extending to
approximately 250,000 acres and containing the Dempsey prospect
(described above) as well as at least three other, Dempsey-style
prospects which have been identified on existing seismic.

About Sacgasco Limited (ASX. SGC)
Sacgasco Limited (ASX: SGC) is an Australian-based energy
company focused on conventional gas exploration in the Sacramento
Basin, onshore California. SGC has an extensive portfolio of gas
prospects at both exploration and appraisal stages, including
multi-Tcf opportunities. The Company is targeting gas supply to the
local Californian gas market and burgeoning LNG market in North
America. SGC is of the view that the size of the prospects in
California have the potential to supply both the domestic
Californian gas market and export LNG markets.
