Oil was discovered in the Janglau-1 well on Block PM308A, offshore peninsular Malaysia, according to Lundin Petroleum.

Janglau-1 was drilled to a total depth of 3,820 m (12,606 ft) by the jackup rig Offshore Courageous.  The objectives of the well were Oligocene intra-rift sands and the underlying fractured pre-Tertiary section.

During drilling below 3,153 m (10,405 ft), oil was found in multiple pay sand units in an intra-rift sand/shale section that extended over a gross interval of approximately 300 m (990 ft). Oil samples were recovered to the surface during drilling.

The well was successfully logged and petrophysical analysis indicates 24 m (79 ft) of net oil pay.  A mini-drill-stem test was successfully completed.

Following completion of the well further work will be undertaken on the data recovered to fully evaluate the discovery and it's potential.

Ashley Heppenstall, Lundin president and chief executive officer, said, "This is Lundin Petroleum's first discovery in this area and follows two prior gas discoveries in the Sabah core area drilled earlier in 2011. Janglau-1 confirms a new oil play.”

The PM308A production sharing contract (PSC) is operated by Lundin Malaysia BV with 35% equity interest. Partners are JX Nippon Oil & Gas Exploration (Peninsular Malaysia) Ltd., 40%, and Petronas Carigali, 25%.

Following completion of Janglau-1 the Offshore Courageous will move to the Bertam-2 appraisal well location in the adjacent PM307 PSC area.
