NNPC - Nigerian National Petroleum Company

In addition to its exploration activities, the Corporation was given powers and operational interests in refining, petrochemicals and products transportation as well as marketing.

Between 1978 and 1989, NNPC constructed refineries in Warri, Kaduna and Port Harcourt and took over the 35,000-barrel Shell Refinery established in Port Harcourt in 1965.

The industry is regulated by the Department of Petroleum Resources (DPR), a department within the Ministry of Petroleum Resources.

The DPR ensures compliance with industry regulations; processes applications for licenses, leases and permits, establishes and enforces environmental regulations. The DPR, and NAPIMS, play a very crucial role in the day to day activities throughout the industry.
