Nigeria: Nigeria’s federal government is set to carry out a comprehensive hydrocarbon mapping of Nigeria’s oil and gas basins, according to Levi Ajuonuma, General Manager – group public affairs, Nigerian National Petroleum Corporation (NNPC). The mapping aims to ensure the efficient exploration for the natural resources across the inland sedimentary areas.
In last six months the NNPC has intensified the search for a commercial crude oil find in the Chad Basin, in line with the present administration’s aspiration to achieve increased crude oil production capacity and reserve. The Chad Basin forms part of Nigerian Frontier Inland Sedimentary Basins, consisting Anambra, Bida, Dahomey, Gongola/Yola and Sokoto basins alongside the Middle/Lower Benue Trough.
Ajuonuma said the hydrocarbon mapping project, which would be the first in the over 100 years history of crude oil exploration in the country, is designed to guarantee precision and exactitude in the evaluation of data in the course of exploration of the inland basins. “The idea is to look beyond the prolific Niger Delta Basin and extend the search to some other basins with good sedimentation and robust tectonic history,” Ajuonuma added.
He said the charge for crude oil find in the Chad basin initiative is being spearheaded by the NNPC’s New Frontier Exploration Services Division, which is also working in consultation with a renowned expert, the United Nations geophysicist and consultant, Deborah Ajakaiye, to ensure that the entire Nigerian Frontier Inland Sedimentary Basins to carry out the proposed hydrocarbon mapping.
According to the consultant, a former president of the American Association of Petroleum Geologists (Africa Region), the hydrocarbon mapping exercise is programmed to cover the aerial and ground survey of the country, to pin-point areas of high potentials as well as identify most prospective oil and gas zones.
“This project entails the comprehensive and systematic airborne geophysical surveys involving gravity, magnetic and electromagnetic surveys of the inland basins with state of the art equipment. It also involves detail integrated programme of geophysical, geological, petrological and geochemical studies,” Ajakaiye said.
