Oil major Shell is said to be in advanced talks with a party interest in buying its onshore operations in Gabon as part of a $30billion divestment plan.
It comes after its purchase of BG Group which was completed earlier this year.
According to reports, Shell informed its staff of the discussions on Thursday.
Bids for the Gabon fields were estimated to be around $700million.
Shell has been operating in Gabon for more than 50 years, and its holdings in the west African country include the Rabi Kounga and Gamba fields.
