Thewell is in Marine XII Block offshore Congo, 35 kilometres fromthe shore and 12 kilometres from the recent Nene' Marinediscovery. It delivered a natural flow of more than 5,000barrels of oil a day and 14 million standard cubic feet of gasa day from a 37 metres section of the 420 metres oil columnwhich has been discovered. The oil quality was 41 degrees API.Eni estimates the potential of the discovery to be about 1billion barrels of oil equivalent, of which 80 percent is oil.The company is appraising the discovery and has begun studyingthe commercial development of the hydrocarbon reserves.

It has already discovered nearly 4billion of barrels of equivalent oil between Congo and Gabon.In the Marine XII permit there have been three discoveries:Minsala Marine, Litchjendily marine and Nene' Marine.
