STOCKHOLM, SWEDEN--(Marketwire - Nov. 23, 2011) -Lundin Petroleum AB (TSX:LUP)(OMX:LUPE) (Lundin Petroleum) is pleased to announce that it has discovered oil in the Janglau-1 well that was drilled in Block PM308A, offshore Peninsular Malaysia.

Janglau-1 was drilled to a total depth of 3,820 metres 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 metres, oil was found in multiple pay sand units in an intra-rift sand/shale section that extended over a gross interval of approximately 300 metres. Oil samples were recovered at surface during drilling.

The well was successfully logged and petrophysical analysis indicates 24 metres of net oil pay. Pressure testing and fluid sampling were completed and oil samples recovered for laboratory analysis. A mini-DST test was successfully completed.

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

Ashley Heppenstall commented: "Janglau-1 results is further validation of Lundin Petroleum's strategy of pursuing organic growth opportunities in focused core areas with evidence of active petroleum systems. This is Lundin Petroleum's first discovery in this area and follows 2 prior gas discoveries in the Sabah core area drilled earlier in 2011. Janglau-1 confirms a new oil play where Lundin Petroleum has built a significant production sharing contract position. Lundin Petroleum together with partners look forward to further exploration drilling in PM308A in the coming years and building on the encouragement provided by Janglau-1".

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

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