Italy’s ENI hit oil and gas offshore the Republic of Congo (ROC) on the Marine XII Block. The discovery was made with the drilling of the Nene’ Marine 1 well, Petroleum Africa has reported.
The well was drilled in 24 meters of water to a total depth of 3,013 meters and encountered a significant wet gas and light oil accumulation in the pre-saline clastic sequence of Lower Cretaceous age. ENI confirmed the Nene’ Marine well with the drilling of the Nene’ Marine 2 well, drilled 2 km away from the discovery well. During production tests both the wells flowed at commercial rates of 37° API gravity oil.
ENI said it estimates the volume of the discovery proved with the two wells so far at around 600 million barrels of oil and 700 Bcf of gas in place. The structure has considerable additional upside that will be evaluated with further delineation wells. 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 JV, New Age with a 25% stake and state SNPC with 10% stake.
