Eni reported a large gas and condensate discovery in the deep sequences of the Obiafu-Obrikom fields on the OML61 block onshore the Niger Delta.
The Obiafu-41 Deep well reached a TD of 4374 m and encountered 130 m of high-quality hydrocarbon-bearing sands within the deltaic sequence of Oligocene age. The find amounts to 1 Tcf of gas and 60 million bbl of associated condensate in the deep drilled sequences. Eni said the discovery has further potential that will be assessed in the next appraisal campaign.
The well will immediately be brought on production and is expected to flow more than 100 MMscf/D of gas and 3,000 B/D of associated condensate, the company said.
The discovery comes amid a drilling campaign planned by Nigerian Agip Oil Company (NAOC), the operating consortium, and aimed at exploring near-field and deep pool opportunities. Eni is operator of NOAC with a 20% interest. Partners are Nigeria National Petroleum Corporation with 60% and Lagos-based Oando with 20%.
Eni’s equity production in Nigeria last year was 100,000 BOE/D. Present in the country since 1962, the company’s exploration and production work there covers some 30,000 sq km onshore and offshore.
