Since the drilling of the first oil well in Masjid-E-Soleyman in the year 1908 and as the birthplace of petroleum industries in Iran, the oil rich regions have acted as the hub of change and development of new technologies for exploration and production of oil and gas.

These changes have gained considerable impetus since the Islamic Revolution and dismissal of foreign experts and contractors. Before then, the oil rich regions of the south were managed by the two special petroleum service companies of OSCO and Non-Industrial Services Company. After the Revolution and the start of the Imposed War, the management of oil-rich regions was established in the National Iranian Petroleum Company to control the oil production in these areas. By the end of the war, this management changed its name to the Onshore Production Management, controlling all operations in the nation.

Finally in the year 2000, the organizational structure of the southern oilfields was reviewed following the ministry of Petroleum''''s new strategy to reform the operations management, leading to the company and nine subsidiaries. Controlling over 50 large and small hydro-fuel fields spread over and area of more than 400,000 square kilometers, extending from the Province of Bushehr to the North of Khuzestan and producing over 83% of the national crude production.

The large oilfields such as Ahwaz Asmari, Gachsaran, Maroun, Karang and Parsi are all situated in this large oil domain. With the recent change in the Ministry of Petroleum''''s approach, we are once again witnessing the application of science and expertixe of the South Oilfields engineers involved in studying and developing the oil and gas fields and reserves.

Currently works are undertaken to develop the oilfields of Kaboud, Mansourabad, Gachsaran, Karanj and Pazanan and the gas fields of Maroun Khami, Aghajari Khalij, Pazanan and Karanj Khami, BibiHakimeh, Karoun Bangestan, qale-nar Bangestan, and Rag-Safid
