The project, known as the Previously Produced Fields (PPF) initiative, aims to recover additional hydrocarbons from the mature Albuskjell, Vest Ekofisk, and Tommeliten Gamma fields, which were shut down in 2019.
“The project involves a joint redevelopment of the three fields, with estimated recoverable gas and condensate resources of 90–120 million barrels of oil equivalent,” ConocoPhillips said.
Planned investments for the three fields total about USD2bn to restart production. First gas is expected in the fourth quarter of 2028, with peak production anticipated at around 36 kb/d, according to the company.
Norway has important hydrocarbon reserves, including 7.7 Gbl of oil (end 2024), which are mainly located in the North Sea (Enerdata Global Energy Research).
