Project Profile
Location: Marine XII Block, offshore Congo
Reserves: 600 million barrels of oil and 19.82 bcm of gas
Production: 7,500 boepd (Phase 1)
Water depth: 3,013 m
Start-up year: December 2014
Eni has made an important oil and gas discovery in the Nene Marine exploration prospect located in the Marine XII Block offshore Congo approx. 17 km from the shoreline. The company estimates the volume of the discovery proved with the 2 wells so far drilled at around 600 million barrels of oil and 700 Billion cubic feet of gas (19.82 bcm) in place. The structure has considerable additional upside that will be evaluated with further delineation wells. The complete development of the field will take place in several stages and will include the installation of production platforms and the drilling of over 30 wells, with a plateau of over 140,000 boepd.
The discovery was made through the well Nene Marine 1, which has been drilled in 24 metres of water to a depth of 3,013 metres. The well encountered a significant wet gas and light oil accumulation in the pre-saline clastic sequence of Lower Cretaceous age. Nene Marine 2 well was drilled 2 kilometres away from the discovery well and confirmed the significant hydrocarbon accumulation and the continuity of the reservoir. During production tests both the wells flowed at a commercial rates oil at 37° API gravity. Eni will continue the appraisal phase of the discovery while starting the studies for the commercial exploitation of this significant hydrocarbon accumulation with the partners of the Joint Venture.
