Hit nominal capacity; platform 180 km offshore; high permo-porosity, thick reservoir supports strong flows; Búzios will host 12 FPSOs with two due in 2027.
Third-quarter results show strong cash flow, production milestones, record refining performance, CCS progress, and a $20B 2027 share-repurchase program.
Deals cover a 50/50 PSA for unconventional hydrocarbons, Absheron FID, LNG export options for Haynesville gas, cloud operator appointment and a 10% Baleine stake.
LOI covers preliminary engineering, procurement and technical services worth about €11m for upstream offshore scope; final EPCI award depends on FID and government/regulatory approvals expected in 2026.
Adds ~30 million boe (mostly gas) and >4 billion m³ of gas; tied to Skarv FPSO with 4.5 kg CO2/boe intensity; lifts Skarv output toward 9 million boe by 2027.
Portfolio concentrated into fewer countries, expected ~USD 20bn free cash flow 2026–2030; US, Brazil and Angola to drive growth; higher margins from high-grading and stepped-up exploration.
Stage 2 began production on 22 August, accelerating 55 billion scm from Troll West, coming online early and several hundred million NOK below the original cost estimate.
Quarterly results bolstered by record own oil output, above-100% refinery utilization and higher derivative production, supporting cash generation and lower imports.
