Serinus Energy Inc.: Brunei-Lukut Updip Well Drilling Update

CALGARY, ALBERTA--(Marketwired - Aug 1, 2013) - Serinus Energy Inc. ("Serinus", "SEN" or the "Company") (SEN.TO)(SEN.TO), an international upstream oil and gas exploration and production company, advises that the exploratory well on its Lukut Updip 1 prospect on Brunei Block L is drilling ahead after having set 95/8" intermediate casing. The Lukut Updip-1 ("LKU-1") well is operated by AED Southeast Asia Limited ("AED SEA") an indirect wholly-owned subsidiary of SEN.

The LKU-1 well, the first exploration well to be drilled during the Brunei Block L Phase 2 drilling campaign, is being drilled as a directional well with a planned measured depth of 2,959 metres (2,431 metres true vertical depth ("TVD")). The well commenced drilling in mid-June and drilled to a measured depth of 1,590 metres (1,372 metres TVD) prior to the running of 95/8" intermediate casing. The well is now drilling ahead to test the primary targets identified for the Lukut Updip prospect. The well is being drilled to test the potential of a triple junction structure that has formed where the Belait and Jerudong Anticlines meet with the Simbatang Fault. The primary targets, the first of which will be penetrated at a depth of approximately 1,400 metres TVD are turbiditic sand deposits of Middle Miocene age with anticipated aggregate thicknesses of 25 to 250 metres. In total five seismically derived targets have been identified within this target interval. Overpressure is expected and the Company is using managed pressure drilling techniques for the drilling of LKU-1. On the spud date the Company estimated that it would take approximately 40 days to drill the well. However, as the upper part of the well took longer than anticipated, the total time for the LKU-1 well to be drilled is now expected to be approximately 65 days. As such the well is expected to reach its total depth in the second half of August.

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.
