ConocoPhillips and its partners have sanctioned a NOK19.5 (€1.6bn, or US$1.8bn) subsea tie-back project in Norway’s Greater Ekofisk Area (GEA) (ConocoPhillips press release, 16/12/2025). The Previously Produced Fields (PPF) project involves redeveloping three gas and condensate fields (Albuskjell and Vest Ekofisk in Block PL018B/F, and Tommeliten Gamma in Block PL044/D) through optimised well placement and the use of horizontal drilling technology.
Recoverable gas and condensate reserves are estimated at between 90 and 120 mboe, ConocoPhillips said. The project comprises four new subsea templates and 11 production wells, all tied back to the Ekofisk complex in the southern North Sea. Plans for development and operation (PDOs) will be submitted to the Norwegian Ministry of Energy in the first quarter of 2026 and first production is expected toward the end of 2028.
ConocoPhillips operates both PL018B/F and PL044/D, with interests of 35.1% and 28.3%, respectively. Other partners include Vår Energi (52.3% in PL018B/F and 9.1% in PL044/D), Orlen Upstream Norway (7.6% in PL018B/F and 62.6% in PL044/D), and Petoro (5% in PL018B/F).
