Eni discovers gas and condensates offshore Gabon

Oilfield Technology,

Eni has made a gas and condensates discovery in the Nyonie Deep exploration prospect located in block D4, approximately 13 km offshore Gabon and 50 km from the capital city Libreville.

Preliminary estimates suggest the new gas discovery is significant, with initial potential in place estimated at 500 million boe. The discovery was made in the pre-salt of Gabon through the NFW Nyonie Deep 1 well, which was drilled in 28 m of water depth, reaching a total depth of 4314 m.

Offshore exploration

The well encountered a thick hydrocarbon bearing section (320 m) in the pre-salt clastic sequence of Aptian age. The structure, which extends more than 40 km2, covers two offshore exploration blocks, both operated by Eni.

The discovery will be followed by an appraisal campaign to assess its potential, which will be carried out shortly. In the meantime, Eni will begin studies for the potential commercial exploitation of the field.

West Africa

The discovery is the outcome of Eni’s exploration campaign in the pre-salt plays of West Africa. This is the third field to be discovered recently in shallow waters in such plays, after Nene Marine and Litchendjili Marine in Congo. The total estimated potential of these discoveries is approximately 3 billion boe, with potential for further improvement.

Eni has operated in Gabon through its affiliate Eni Gabon since 2009 and currently has exploration activities in four exploration licences.
