After the victory of the Islamic Revolution of Iran, all partnership contracts with aforementioned companies were aboilished at the decree or the Supreme Council of the Islamic Revolution in 1979, and a year later, the Iranian Offshore Oil Company (IOOC) was established by combining those companies. The objective underlying establishment of IOOC was to achieve an optimized production as well as safeguarding oil and gas reservoirs in the Persian Gulf area along with an increase in the production rate and prevention of oil and gas migration in the common fields,… and in a word, to administer the entire oil and gas fields in the Persian Gulf where the American and European companies had previously carried out the oil activities.

The incidents during the imposed war of Iraq against Iran with considerable damages it the offshore and onshore facilities, aimed to stop our production, placed a great challenge before IOOC to achieve its most important goal which was oil production. Facing this challenge required self- sacrifice and industrious efforts of all the personnel concerned. Today conspicuous record of the company despite all ups and downs, is the best evidence for this accomplishment.
