ENI has discovered oil and gas at Nene’ Marine 1 and Marine 2 wells in the Nene’ Marine exploration prospect, offshore 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 Lower Cretaceous age. The Nene’ Marine exploration prospect is located in the Marine XII Block, offshore of Congo at about 17km from the shoreline. The Marine 2 well, which was drilled two kilometres away from the discovery well, showed hydrocarbon accumulation and the continuity of the reservoir.
ENI said both wells flowed at commercial rate oil at 37° API gravity during production tests. The volume of the discovery with the two wells is estimated at around 600 million barrels of oil and 700 billion cubic feet of gas. « Nene’ Marine exploration prospect is located in the Marine XII Block. »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 owned subsidiary ENI Congo, is the operator of Marine XII block with a 65 percent stake, while New Age and Societé Nationale des Pétroles du Congo (SNPC) hold 25 percent and ten percent stakes.
The company currently has an equity production of 110,000 barrels of oil per day in Congo.
