Serinus Energy Inc.: Ukraine-NM-3 Well Tests Oil and Gas-Potentially Opening Up a New Play in the North Makeevskoye Exploration Licence

Serinus Energy Inc. (SEN.TO)(SEN.TO) (formerly Kulczyk Oil Ventures Inc. - "Serinus" or the "Company"), an international upstream oil and gas exploration and production company, is pleased to announce that an open hole test of the North Makeevskoye-3 ("NM-3") exploration well recovered oil and gas from Visean aged rock formations underlying the North Makeevskoye Exploration Licence.

The NM-3 well, the third well drilled on the North Makeevskoye Exploration Licence, is located 3 kilometres southeast of the North Makeevskoye-1 well. It is a deviated well which reached a total depth ("TD") of 2,426 metres (measured depth) after penetrating the metamorphic basement.

The well took 54 days to reach TD after spudding on May 30, 2013. Petrophysical analysis of the logs identified a 30 metre thick Visean aged sandstone as being potentially oil saturated. An open hole drill stem test was conducted over the interval 2,344 metres to 2,426 metres measured depth. The test recovered 0.5 m³ of 37° API oil and minor amounts of produced gas were flared. Fluid samples have been collected for laboratory analysis. The well has been cased to TD to allow for further testing.

The Company believes that the well may be capable of producing at commercial rates after stimulation. Further analysis of the full diameter core recovered over the zone of interest, petrophysical analysis and fluid analysis will be required to fully assess the prospectivity of this formation. A positive oil test is a first for the Company in Ukraine and is of particular importance as it is the first indication that the Visean formations are hydrocarbon bearing within the Company's licences. Positive results from this deeper Visean reservoir has the potential to develop into a new play and increase the resource potential of the Company's Ukrainian assets.

Jock Graham, Executive Vice President & COO, commented that:

"While the log analysis indicated that the formation was potentially hydrocarbon bearing, the reservoir also looked very tight, and we weren't really expecting much in the way of hydrocarbon recovery. Consequently we were pleasantly surprised that both oil and gas were recovered from the well. As a result, the well is being cased for future testing as the Company believes that the well may be capable of producing at a commercial rate after stimulation. Aside from the fact that oil was recovered on test, which is a first for us in Ukraine, of particular importance is that the oil was recovered from the Visean reservoir, a deeper reservoir that the company has never produced from, so it potentially opens up a new play for us."

The NM-3 well is operated by KUB-Gas LLC, a majority-owned subsidiary in which the Company has a 70% effective ownership interest.
