Mari Gas Company Limited has made a significant new gas discovery in Koonj Well # 1A in the Sukkur Exploration Block. This momentous success of the Sukkur Joint Venture is also happy news for the country; adding indigenous source to nation’s gas reserve base which would result in substantial savings of foreign exchange. The Sukkur Joint Venture comprises MGCL –Operator with 50% interest share, Petroleum Exploration Limited (PEL) 35%, a Pakistani exploration and production company and International Sovereign Energy Corp. 15% a Canadian exploration and production company.

The well was spud-in on April 22, 2008 and drilled down to a depth of 1475 meters in Pab Sandstone of Cretaceous age. Based on the wire-line logs, drilling data and geological information, the well was tested using drill stem testing methods. As a result the Koonj Well # 1A discovery was made in the Sui Main Limestone Formation which tested minimum gas flow rate of 14.28 MMSCF/Day with wellhead pressure of 727 psi at 48/64” choke size. The discovered gas has a heating value of 860 BTU/SCF. The flow rates from the well are expected to increase significantly with acidization treatment which is planned to be conducted after well completion.

Company has also conducted extensive exploration activities in the Block area. There exist two other prospects within Sukkur Block area, which will be drilled shortly.

MGCL being  one of the major gas producers of the country  has also made three new gas discoveries viz. (i) Mari - Sui Main Limestone, (ii) Mari - Pirkoh Limestone Formation and (iii) Ziarat Gas Field.
