London, United Kingdom | – Italian energy major Eni has made a gas and condensates discovery in the Nyonie Deep exploration prospect located in Block D4 about 13 km (8 miles) from the coast of Gabon, according to a press release.
Preliminary estimates suggest the new gas discovery is significant with initial potential in place estimated at 500 MMboe. The discovery was made in the presalt of Gabon through the NFW Nyonie Deep 1 well, which was drilled in 28 m (92 ft) of water depth reaching a total depth of 4,314 m (14,154 ft).
The well encountered a thick hydrocarbon-bearing section (320 m [1,050 ft]) in the presalt clastic sequence of Aptian age. The structure, which extends more than 40 sq km (15 sq miles), covers two offshore exploration blocks both operated by Eni with a 100% stake.
The discovery will be followed by an appraisal campaign to assess its potential.
