Total has signed a concession agreement with Algerian state-owned Sonatrach, Repsol, and Alnaft for a 25-year licence extension for the Tin Fouye Tabankort (TFT) gas and condensate field, Reuters reported.

The agreement will give Total a 26.4% share, while Sonatrach and Repsol retain 51% and 22.6% stakes respectively.

The stakeholders will undertake the drilling and development investments to extract additional reserves estimated at more than 250 million barrels of oil equivalent.

“These investments will allow them to maintain production of the field, which is currently over 80,000 barrels of oil equivalent per day for six years,” Total said in a statement.
