Serinus Energy Inc.: Ukraine: Olgovskoye-11 Finds Multiple Gas Zones

CALGARY, ALBERTA - Serinus Energy Inc. (SEN.TO)(SEN.TO) ("Serinus", "SEN" or the "Company") is pleased to announce that the Olgovskoye-11 ("O-11") development well has been drilled to its total depth ("TD") of 3,230 meters. Logging is now complete and has identified net pay in four zones of Bashkirian or Serpukhovian age, three of which have been established as productive within the Company's Ukrainian Licences. The operator, KUB-Gas LLC ("KUB-Gas") has set production casing and a testing programme will begin once the workover rig currently on the Makeevskoye-17 ("M-17") well finishes its operations there. The drilling rig will now move from O-11 to the North Makeevskoye-4 location to test a seismically-identified stratigraphic play. Drilling is expected to commence by the end of June. KUB-Gas is a partially owned subsidiary in which Serinus has a 70% effective ownership interest through its 70% interest in KUBGAS Holdings Limited.

O-11 Finds Multiple Stacked Gas Zones

The O-11 well was drilled as a step out location from the O-9 well with respect to the Bashkirian R30c zone, and to appraise the gas discovery made in the S6 sandstone in O-15. It is located about 1 kilometre to the south of O-15 within the same structural closure. Drilling commenced in early April 2014 and reached TD on May 18^th. Cores were cut in both the R30c and S6.

The following table shows the results of the log analysis for the four zones encountered:

Summary Log Results for O-11

The two primary targets are the R30c and S6 zones.

R-30c

Preliminary inspection of the core from the R30c indicates that it is a fine grained sandstone with minor shale laminations, similar to that found in the O-15 and O-6 wells. Initially, the R-30c zone in O-6 was not capable of commercial flow rates, but commenced production in early 2012 at 1.5 MMcf/d after being stimulated. No gas-water contact is seen in the R-30c in O-11, and the Company anticipates no issues in stimulating it as well.

S6

Initial inspection of the core from the S6 sandstone indicates a clean sand with no observed gas-water contact, similar to the S-6 in O-15 which commenced production in August 2013 at an initial rate of 1.7 MMcf/d, and did not require stimulation.

The B8b and S7 zones are secondary targets, and logs indicate potential pay in both formations. Testing will be required on both zones to confirm this potential.

Olgovskoye Field

Olgovskoye is Serinus' second largest producing field at 12.4 MMcf/d (8.7 MMcf/d net to SEN 70% WI) from 10 wells. Most of the production is from Bashkirian aged sandstones, and with the success in the Serpukhovian in both O-15 and O-11, the Company's future exploration and development efforts will include that deeper section as well.
