Italian oil and gas company Eni has discovered significant wet gas at Nene Marine 3 exploration well in the Marine XII block located about 17km offshore Congo.
The Nene Marine 3 well, which led to the gas discovery, was drilled in a water depth of 28m and has encountered gas and light oil accumulation in the pre-salt clastic sequence.
Located 2km from the discovery well Nene Marine 1 and 4km from Nene Marine 2, the well flowed more than 5,000bpd at 36° API gravity, during the production test in the oil interval.
Following the well's successful results, the company estimates that the discovery of Nene Marine field contains 1.2 billion barrels of oil and 30 billion cubic metres of gas.
The Nene Marine and the neighbouring Litchjendilj Marine fields are claimed to have overall potential of approximately 2.5 billion barrels of oil equivalent in place.
Eni, which controls 65% of the Marine XII block, activated studies with the joint-venture's partners New Age (25%) and SNPC (10%) to ensure a commercial development of the hydrocarbon reserves in a bid to launch first oil production in 2016.
The next exploratory and delineation campaign by the company will determine the significant additional exploration upside of the block.
Present in Congo since 1968, Eni has an equity production of 105,000bpd in the country and its existing operated production in the region is approximately 450,000bpd.
The company participates in exploration and production projects in Angola, Congo, Ghana, Gabon, Mozambique, Nigeria, Democratic Republic of Congo, Kenya and Liberia.
