Serinus Energy Inc./Ukraine: M-17 Tests Gas in S7 Zone, a New Pool Discovery

CALGARY, ALBERTA--(Marketwired - May 6, 2014) - Serinus Energy Inc. ("Serinus", "SEN" or the "Company") (TSX:SEN)(WARSAW:SEN), an international upstream oil and gas exploration and production company, is pleased to announce that the S7 zone in the Makeevskoye-17 ("M-17") well tested gas at a rate of over 0.9 million standard cubic feet per day ("MMcf/d") through a 7 millimetre choke.

The S7 has 5.5 metres of net pay and is a new pool discovery as it has not been previously produced elsewhere on the Company's licenses. Serinus currently carries no reserves for the zone. While logs had indicated the S7 as potentially hydrocarbon-bearing, stimulation had been deemed necessary to get a commercial rate, and consequently, the Company was pleasantly surprised by the test result. Stimulation is still being considered for the S7, and as such it remains in the campaign currently scheduled for October this year.

Gas samples taken during testing indicate that the gas has a carbon dioxide ("CO₂") content of 8.8% and a heating value of 6,960 kilocalories per cubic metre ("kcal/m³"). While this is below the sales gas pipeline specification of 7,600 kcal/m³ and 2% CO₂, it can be mingled with production from the Makeevskoye and Olgovskoye fields and the resulting blend will meet or exceed all pipeline requirements. Serinus is confident that the gas composition will not pose any material issues in development.

The plan now is to dually complete M-17 as an S6/S7 producer, with the S7 producing unstimulated. This will require the snubbing unit to avoid having to kill and potentially damage either formation. The snubbing unit is currently performing operations on the O-4 well. Until it arrives, M-17 will be suspended. A bridge plug will then be set above the S7, after which the S6 zone, which is the primary target in the M-17 well and 45 metres above the S7, will be perforated and tested. Wireline logs indicate 9 metres of net gas pay in the S6.

"The S7 test results are very encouraging, and potentially open up a new play in the Company's licences. We are also pleased that work is continuing uninterrupted through this stressful period in Ukraine, thanks to the efforts and dedication of our Ukrainian staff" - said Jock Graham, Executive Vice President and Chief Operating Office of Serinus.

M-17 was drilled to a total depth ("TD") of 3,475 metres in early March to appraise the gas discovery made in the S6 sandstone in M-16 well, which is currently producing at a rate of 3.9 MMcf/d. In addition to the S7 and S6 zones, wireline logs on M-17 indicate 2.5 metres of net pay in the S5 carbonates and 22 metres of resource potential in the R30c.

The M-17 well is operated by KUB-Gas LLC, a partially-owned subsidiary in which SEN has a 70% effective indirect ownership interest through its 70% shareholding of KUBGas Holdings Limited.
