Empyrean Energy PLC ("Empyrean" or the "Company")

Operations Update for 1+ Tcf Dempsey Natural Gas Well

· Surface conductor in place ready for the Dempsey 1-15 well

· Drilling rig mobilization underway

Empyrean, the oil and gas development company with interests in China, Indonesia and the United States, is pleased to announce that it has been advised by Sacgasco Limited ("Sacgasco") (ASX:SGC), the operator of the Company's Sacramanto Basin assets onshore California, that installation of the surface conductor for the Dempsey 1-15 Appraisal and Exploration Project is now complete.

Empyrean will have a 30% Working Interest in the Dempsey 1-15 well. The Company refers shareholders and interested parties to the announcement made by Sacgasco earlier today on ASX which can be found at http://www.sacgasco.com/wp-content/uploads/2017/07/Dempsey-Surface-Conductor-Installed.pdf and which includes photos of the drilling and cementing operations for the conductor and also shows the proximity of the JV owned gas metering station to the drill pad.

The well is currently on track to spud later this month.

Participants in the Dempsey 1-15 gas well will be:

Empyrean Energy Plc 30% (AIM: EME)

Sacgasco Limited 50% (ASX : SGC)

Pancontinental 10% (ASX : PCL)

Xstate Resources Limited 10% (ASX : XST)

Further announcements will be made in due course.

Tom Kelly, Empyrean CEO, commented: "Empyrean is delighted with the progress being made on the ground in preparation for drilling the very high potential impact 1+ Tcf Dempsey 1-15 gas well. This very exciting well comes fresh off the back of our recent exploration success at the Mako well in Indonesia. Our gas metering station is in very close proximity to the drilling location and paves the way for any gas discovered at Dempsey to be connected to existing infrastructure for early cash flow both quickly and cheaply. "

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. Empyrean recently participated in drilling the Mako South-1 well which has recorded better than expected flow rates, porosity, permeability and gas saturation in the target Intra Muda Formation. A stabilised flow rate of 10.9 million cubic feet of gas per day with multi Darcy permeability and excellent reservoir characteristics was recorded.

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' (Empyrean earning 30%) and 'Alvares' (Empyrean earning 25%) and an Area of Mutual Interest (the "Dempsey Trend AMI")(Empyrean earning 30%) 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 will be drilling and testing the Dempsey Prospect, a 1 Tcf gas target in Q3, 2017.

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.
