Eni has discovered oil and gas at the Nene' Marine 1 and Marine 2 wells in the Nene' Marine exploration prospect offshore the Democratic Republic of the Congo.
Eni drilled the Marine 1 well in 24m of water to a depth of 3,013m and found wet gas and light oil accumulation in the pre-saline clastic sequence of the Lower Cretaceous age.
The Nene' Marine exploration prospect is located in the Marine XII block offshore Congo at about 17km from the shoreline. The Marine 2 well, which was drilled 2km away from the discovery well, showed hydrocarbon accumulation and the continuity of the reservoir.
Eni said both wells flowed at commercial rates of 37° API gravity during production tests.
The volume of the discovery at the two wells is estimated at around 600 million barrels of oil and 700 billion cubic feet of gas.
Eni will evaluate additional upside at the structure with further delineation wells and continue the appraisal phase of the discovery.
The company will start studies for the commercial exploitation of the hydrocarbon accumulation with the partners of the joint venture.
Italy-based Eni, through its subsidiary Eni Congo, is the operator of the Marine XII block with a 65% stake, while New Age and Societé Nationale des Pétroles du Congo hold 25% and 10% stakes respectively.
The company currently has an equity production of 110,000bpd in Congo.
