IN THE BEGINNING
Petroleum matters were handled by the Hydrocarbon Section of the Ministry of Lagos Affairs, which reported directly to the Governor-General. .
The Unit kept records on matters relating to exploration, and importation of petroleum products. It also enforced safety and other regulations on matters which were then mostly products importation and distribution. As the activities of the petroleum industry expanded, the Unit was upgraded to a Petroleum Division within the Ministry of Mines and Power.
