Oil, Gas and Condensate Discovery in Karak Block – Punjab Province

Mari Petroleum Company Limited (MPCL) has struck another significant Crude Oil, Condensate and Natural Gas discovery in its Karak Block’s Kalabagh-1A ST1 Well located in District Mianwali.

Karak Joint Venture is operated by MPCL holding 60% working interest with MOL having 40% share. Kalabagh-1A ST1 discovery is the Company’s 2nd success in the block in Datta, Samanasuk and Lockhart formations; after its first major Crude Oil discovery in the block made at Halini Well-1 in 2011.

Kalabagh-1A ST1, spud-in on March 20, 2015, is the Company’s 2nd exploratory well in Karak Block. It has been successfully drilled down to a depth of 3,003 meters in Datta Formation. During testing, the well flowed Gas & Condensate in Datta Formation at a rate of 3.3 MMSCFD and 160 BBL/D respectively, with wellhead pressure of 694 Psi at 32/64” choke size. The gas discovery has an excellent heating value of 1144 BTU/SCF and its Condensate API is 52 @600F. The Well has also been successfully tested in Samanasuk Formation, which also flowed Gas and Condensate at a rate of 4.68 MMSCFD and 180 BBL/D respectively, at a wellhead pressure of 926 Psi at 36/64” choke size with excellent gas heating value of 1128 BTU/SCF and Condensate of 58 @600F API. The testing of Lockhart Formation flowed commercial quantity of Crude Oil @500 BBL/D with wellhead flowing pressure of 155 psig of 22 API @600F at 32/64” choke size.

The Kalabagh discovery becomes another source of indigenous energy supply which is expected to add significantly to the nation’s hydrocarbon reserve base; thus contributing towards the saving in foreign exchange and bridging the demand and supply gap.

Additionally, MPCL is drilling its 3rd exploratory well Halini Deep -1 in the block which is currently at the depth of 5,669 meters into Chhidru Formation and is amongst the very few wells being drilled down to such lower depth.

Kalabagh-1A ST1 discovery has augmented MPCL exploration well success rate, which already ranks highest in the country. MPCL presently, operates two Development & Production Leases, nine Exploration Licenses and has joint venture interest share in six other Exploration Blocks.
