Serinus Energy Inc.: Ukraine-Olgovskoye-24 Well Cased As Potential Producer

CALGARY, ALBERTA--(Marketwired - Oct. 29, 2013) - Serinus Energy Inc. (TSX:SEN)(WARSAW:SEN) ("Serinus", "SEN" or the "Company"), an international upstream oil and gas exploration and production company, is pleased to report that the Olgovskoye-24 ("O-24") well has been cased to total depth ("TD") as a potential gas producer. The O-24 well is operated by KUB-Gas LLC ("KUB-Gas"), a partially-owned subsidiary in which Serinus has an effective 70% ownership interest through its 70% shareholding of KUBGas Holdings Limited.

The O-24 well commenced drilling in August with an original planned TD of 2,900 metres with the principal target being the Bashkirian B6 zone. During the course of the drilling it was decided to deepen the well to penetrate the Serpukhovian as the Company believed that the zone discovered in the O-15 well extended to the northwest. Consequently the O-24 well was drilled to a final TD of 3,300 metres and logged. The logs indicate 15 metres of potential pay in 4 different zones within the Bashkirian and Serpukhovian. Production testing of the well is scheduled to occur prior to year end. The main target of the well, the B6 sandstone currently producing in the O-12 well, was encountered at a depth of 2,285 metres with a gross thickness of 22 metres and with 5 metres of gas pay interpreted on logs. The S6 zone, encountered at a depth of 3,162 metres, is also sandstone with a gross thickness of 10 metres and with 3.5 metres of gas pay interpreted on logs. In addition potential pay was interpreted on the logs in the R30c and the B4b zones. The O-24 well is located approximately 1 kilometre to the northwest of the Olgovskoye-12 well, a B6 zone gas discovery which reached TD in September 2011 and which is currently producing more than 3.5 million cubic feet per day ("MMcf/d") (2.45 MMcf/d net to Serinus' 70% interest).

The KUB-Gas owned drilling rig, that was used to drill the O-24 well, will now be moved approximately 14 kilometres to the southeast to drill the Makeevskoye-17 ("M-17") well, which will be drilled to a target depth of 3,450 metres to evaluate the gas potential of the Serpukhovian S5 and S6 zones. The M-17 well location is about 1 kilometre to the northwest of Makeevskoye-16 ("M-16"), the deepest well drilled on the Makeevskoye Licence to date. M-16 was drilled to a TD of 4,300 metres in the third and fourth quarter of 2012 and subsequently tested gas from the S6 zone at a maximum rate of 4.3 MMcf/d (3 MMcf/d net to Serinus' 70% interest). The M-16 well was tied-in for commercial production in June 2013 and current production from the S5 zone is more than 3.6 MMcf/d (more than 2.5 MMcf/d net to Serinus' 70% interest).

Jock Graham, Executive Vice President & Chief Operating Officer of Serinus said - "This well looks like it will extend the limit of the productive area of the Olgovskoye Field and will provide incremental production for the project. The exploration of the deeper Serpukhovian zones continues to deliver positive results and we'll be looking to continue to follow-up on our recent Serpukhovian discoveries."
