Most Significant Gas Shows to Date at Dempsey 1-15 Well
-- Drilled through hard siltstone/shale section into a primary gas bearing sand
-- Drilling ahead below 2,760 m (9050 feet) to evaluate
remaining conventional sandstone reservoir targets in next
approximately 440 m (1,400 feet) of drilling
-- Dempsey is testing the largest undrilled structure in northeastern Sacramento Basin
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 the Dempsey 1-15
well is currently drilling ahead in 8 1/2" vertical hole.
After penetrating a thick section of hard shales and siltstones,
drilling yesterday has intersected a potential sandstone reservoir
with high gas shows. These have occurred even though the drilling
mud weight has been further increased to control the levels of
background gas for safe drilling.
Shareholders and investors are advised that the significance of
these shows will become more apparent when the next wireline logs
are run to more fully evaluate the intersected gas shows and
reservoirs. This is planned after reaching the proposed total
drilling depth of approximately 3,200 metres.
The Dempsey 1-15 well is currently drilling ahead below 2,760 m
(9,050 feet) to the highly under-explored deeper targeted
reservoirs in the approximately 440 m (1,400 feet) of remaining
section to be drilled.
Dempsey is drilling the largest undrilled mapped structural
closure in the northeastern part of the prolific Sacramento Gas
Basin and is interpreted to be optimally located to trap gas
migrating out of gas generating areas located to the west and
south.
Empyrean CEO Tom Kelly commented, "After slow and steady
drilling through some very hard rocks over the last few days, we
are very encouraged to see the best looking gas shows from another
sand in what we now believe to be part of the primary target zone
in this well. We have not drilled out of this latest gas bearing
sand yet, so it will be interesting to see how thick this zone is.
We look forward to keeping investors appraised as we progress."
Dempsey Prospect and Dempsey 1-15 Well
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. Individual, unrisked Deterministic Prospective
Resources for the primary targets range from 116 Bcf to 352 Bcf of
recoverable gas. Should all the stacked reservoirs be full of gas,
the cumulative unrisked recoverable Prospective Resources within
the Dempsey prospect could exceed 1 Tcf.
The primary targets are interpreted in a series of Cretaceous
sandstone reservoirs that exhibit structurally consistent amplitude
anomalies similar to those that are observed on seismic data
elsewhere in the basin where conventional sandstone reservoirs have
trapped natural gas in mapped structural closures, for example the
Tulainyo / James and Alvares wells.
Sacgasco expects to intersect gas shows in a number of zones in
the Dempsey 1-15 well and these will be assessed based on the
information available, but quantitative results will need to await
conventional logging after drilling each section of the well and
may need flow testing to be definitive.
The Dempsey 1-15 well is planned to be drilled in three discrete
sections to depths of approximately 600m, 2,000m and 3,200m
associated with decreasing planned casing sizes. The well has been
designed conservatively to provide flexibility to respond to well
bore conditions and progressive results.
Empyrean has also been informed that since the Dempsey 1-15 well
will be exploring for a new gas pool, Sacgasco has requested that
the regulator keep the records confidential for two years as
allowed by Section 3234 of the Public Resources Code of California.
The regulator has approved the "Confidential Status" for Dempsey
1-15 in order to protect longer-term shareholder value.
Aside from compelling technical merit, the Dempsey 1-15 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 announcement has been reviewed by Empyrean's Technical
Director, Mr Frank Brophy BSc (Hons), who has over 40 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 commenced 3D seismic Q2, 2017 to further mature two
large oil prospects, Jade and 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 Company plans
to commence a 3,200 metre (10,500 feet) combined appraisal and
exploration well, Dempsey-1, in Q3 2017 to evaluate this
prospect.
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 drilling and 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.
