Petroleum industry in Pakistan

According to the United States Energy Information Administration (EIA), Pakistan may have over 9 billion barrels of petroleum oil and 105 trillion cubic feet in shale oil and natural gas reserves.

As per BP' Statistical Review of World Energy 2016, at the end of 2015 Pakistan had the following proved reserves of fuels: 0.5 Trillion cu m of natural gas and 2.07 Billion tons of coal (sub-bituminous and lignite).

Pakistan's first gas field was found in the late 1952 in Balochistan near a giant Sui gas field. The Toot oil field was not discovered until the early 1960s in the Punjab. The Most Rich resource in Khaur Company (Attock). It covers 122.67 square kilometres (47.36 sq mi). Pakistan Petroleum and Pakistan Oilfields explored and began drilling these field with Soviet help in 1961 and activity began in Toot during 1964.

The Toot area is one of the oldest oil producing regions in Pakistan with the first oilwell drilled in 1964 when President Ayub Khan encouraged a mineral development policy. It is located in the Pothohar Plateau, Punjab Province, which is located approximately 135 km southwest of the capital city of Islamabad. In 1964 the first well was drilled and commercial production started in 1967. There are about 60 million barrels of oil in place of which 12%-15% is recoverable. At its peak during 1986, the field was producing approximately 2,400 barrel of oil per day. It has grown steadily since then, producing both oil and, to a lesser degree, natural gas. Oil production was entirely confined to the Potwar Plateau till 1981, when Union Texas Pakistan discovered its first oil-field in Lower Sindh. By 1998-1999, the Lower Sindh gas-fields were producing more oil than the Potohar Plateau. Since then, new deposits have also been found here.
