Name of the Project
TWIN gas project.

Location
The northern part of the Troll West gas cap, within the Troll field in blocks 31/2, 31/3, 31/5 and 31/6, in the northern North Sea, about 65 km west of Kollsnes, near Bergen, Norway.

Project Owner/s
Equinor Energy (30.55%) and operator, Petoro (55.93%), A/S Norske Shell (8.19%), TotalEnergies EP Norge (3.69%) and ConocoPhillips Skandinavia (1.64%).

Project Description
TWIN, or Troll West increased gas recovery North, is the third step in the phased development of the Troll West gas cap.

The subsea project will comprise two wells in a new template and a pipeline connected to existing subsea facilities. The control cable/umbilical and monoethylene glycol line will be extended to the new development.

Gas will be produced through Troll A and sent to the Kollsnes processing plant.

The project is expected to contribute about 11-billion standard cubic metres of gas.

Potential Job Creation
Equinor has said the project will help sustain jobs and value creation but has not disclosed a project-specific employment estimate.

Capital Expenditure
Just over NKr4-billion.

Planned Start/End Date
Production is targeted to start as early as 2028.

Latest Developments
The partnership sanctioned the development and completed an environmental-impact assessment in June 2026. By July 7, 2026, the partnership had notified Norway’s Ministry of Energy of the development in accordance with the Petroleum Act.

Key Contracts, Suppliers and Consultants
