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.


Being one of the largest petroleum exploration and production companies in Pakistan, we visualize the earth as something beautiful and mysterious, for it has so many secrets to reveal.
