Equinor and Partners to Invest $390 Million Adding Two Wells at Troll Field

Equinor and its partners will invest more than NOK 4 billion ($390 million) to expand the Troll field in the North Sea. The project, called TWIN, will add two new wells tied back to existing subsea infrastructure. Production from the TWIN development is expected to begin as early as 2028.

Gunnar Nakken, Equinor's Senior Vice President for Projects and Subsea Norway, said the company aims to start output that year by simplifying designs, increasing standardization, and reusing existing infrastructure and equipment. The TWIN project marks the third phase of Troll Phase 3. The second stage of Troll Phase 3 is scheduled to come online in 2026.

The Troll field supplies around 10% of Europe's natural gas and contains 40% of Norway's remaining gas reserves. Equinor stated that gas from Troll alone covers about 10% of Europe's annual natural gas demand. The TWIN wells are expected to unlock around 11 billion cubic meters of natural gas, equivalent to roughly 69 million barrels of oil equivalent.

Com reported that this volume would cover roughly 2% to 3% of annual European gas demand and is roughly equivalent to Belgium's yearly natural gas consumption. The development will use a new subsea template with two wells connected to current facilities. Existing umbilical and MEG systems will be extended to support production.

The Troll A platform and the Kollsnes processing facility are powered by electricity from shore.
