Company History

The Mari Gas Field, originally owned by the Pakistan Stanvac Petroleum Project (a joint venture formed in 1954 between the Government of Pakistan and M/s Esso Eastern Incorporated U.S.A), made its first gas discovery in the lower Kirthar Limestone Formation in 1957. The field came on stream in 1967. M/s Esso Eastern sold its entire shareholding to the Fauji Foundation, Government of Pakistan (GoP), and Oil and Gas Development Company Limited (OGDCL) in 1983. The company continued as a wholly-owned Public Limited Organization. The company has grown from the sale of natural gas from an inherited field to become one of the leading integrated E & P companies in the country.
