POL is a subsidiary of The Attock Oil Company Limited (AOC) incorportated on November 25, 1950. AOC was founded in 1913 and made its first oil discovery in 1915 at Khaur, District Attock. AOC has, therefore, pioneered exploration and production of oil and gas in this region nearly a century ago. In 1978, POL took over the exploration and production business of AOC. Since then, POL has been investing independently and in joint venture with various exploration and production companies for the search of oil and gas in the country.
