[4] In response to this requirement, Attock Oil Company incorporated Pakistan Oilfields Limited, in which it held a shareholding of 70 percent.

[4] Despite this, the anticipated rise in locally sourced crude oil led to the need for substantial expansion of the refinery's facilities.

[4] With the successful completion of the second phase in 1981, Attock Refinery fulfilled its contractual expansion obligations with the government, leading to the dissolution of the specialized project management section.

[4] In March 1994, the Government of Pakistan introduced the Petroleum Policy which removed profit caps for refineries undertaking expansion and development.

[4] Later, Attock Refinery commissioned Hagler Bailey to conduct a feasibility study, including a sensitivity analysis on the impact of different crude types on the project's viability.

[4] The study affirmed the feasibility across various conditions, leading to the board of directors approving the Refinery Upgradation and Expansion Plan (ARU Project) by the end of 1994.

[4] In January 2003, the Government of Pakistan sold its 35 percent stake in Attock Refinery to general public for PKR 102 per share.
