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 percent working interest with MOL having 40 percent share. Kalabagh-1A ST1 discovery is the company's second 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, is the Company's second 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 and 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 psi 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 third 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.
