Serinus Energy Inc.: Brunei-Luba Well Commences Drilling

CALGARY, ALBERTA--(Marketwired - Nov. 12, 2013) - Serinus Energy Inc. (TSX:SEN)(WARSAW:SEN) ("Serinus" or the "Company"), an international upstream oil and gas exploration and production company, is pleased to announce that the Luba-1 exploratory well on Brunei Block L commenced drilling on 11 November 2013. The Luba-1 well is operated by AED Southeast Asia Limited ("AED SEA"), an indirect wholly-owned subsidiary of Serinus.

Luba -1 Well

Luba-1 is the second of two commitment wells to be drilled during the 2013 Brunei Block L Phase 2 drilling campaign. The well is planned to evaluate the hydrocarbon potential of the Triple Junction structure, within the Luba Fault Block south-west of the Lukut Updip-1 gas well drilled earlier this year.

The Luba Prospect was interpreted using the 2009 Tutong 3D seismic volume, and is planned to be drilled as a directional well to test a Direct Hydrocarbon Indicator ("DHI") or "Flat Spot" observed in the B horizon in the Luba Fault Block. Unlike Lukut Updip-1 which targeted deep water sand bodies contained within the Setap shale formation, the Luba prospect will target shoreface to near shore deltaic sandstones of Pliocene to Late Miocene age, which are the traditional exploration targets in Brunei. In addition to evaluating the primary target (B Horizon), the Luba-1 well will also evaluate the shallower R Horizon. Both horizons are located in interpreted trap position created by two extensional normal faults which form the Luba fault block. The primary B Horizon target, is expected to be encountered at a depth of approximately 2,802 metres measured depth (2,360 metres true vertical depth), and the well is expected to take approximately 35 days to drill. Formations are anticipated to be normally pressured.

Prospective Resources for the Luba prospect were estimated by independent reserve engineers RPS Energy Consultants Ltd. ("RPS") in their report dated 12 November 2012 and range between a High Estimate of 77 million barrels of oil equivalent ("MMboe") and a Low Estimate of 10 MMboe, with a Best Estimate of 32 MMboe. These estimated Prospective Resource volumes, which are un-risked and are for the net 90% interest of Serinus' in the Luba Prospect.

Serinus has a 90% interest in the Block L with indirect wholly-owned subsidiary Kulczyk Oil Brunei Limited having a 40% interest and indirect wholly-owned subsidiary AED SEA (operator) having a 50% interest. The remaining 10% interest is owned by a private Brunei company at arm's length to Serinus.

Cautionary Statement

There is no certainty that any portion of the Prospective Resources will be discovered. If discovered, there is no certainty that it will be commercially viable to produce any portion of the Prospective Resources.

Defined Terms

"Prospective Resources" are those quantities of petroleum estimated, as of a given date, to be potentially recoverable from undiscovered accumulations by application of future development projects. Prospective Resources have both an associated chance of discovery and a chance of development. Prospective Resources are further subdivided in accordance with the level of certainty associated with recoverable estimates assuming their discovery and development and may be sub-classified based on project maturity.

"Low Estimate" is considered to be a conservative estimate of the quantity that will actually be recovered. It is likely that the actual remaining quantities recovered will exceed the low estimate. If probabilistic methods are used, there should be at least a 90 percent probability (P90) that the quantities recovered will equal or exceed the low estimate.

"Best Estimate" is considered to be the best estimate of the quantity that will actually be recovered. It is likely that the actual remaining quantities recovered will be greater or less than the best estimate. If probabilistic methods are used, there should be a 50 percent probability (P50) that the quantities recovered will equal or exceed the best estimate.

"High Estimate" is considered to be an optimistic estimate of the quantity that will actually be recovered. It is unlikely that the actual remaining quantities recovered will exceed the high estimate. If probabilistic methods are used, there should be at least a 10 percent probability (P10) that the quantities recovered will equal or exceed the high estimate.
