Equinor and the partners in the Troll licence today submit the plan for further development of the gigantic Troll field on the Norwegian continental shelf (NCS) to the Ministry of Petroleum and Energy.

“The third phase of the Troll development realises 2.2 billion barrels of oil equivalent, it has a break-even of less than USD 10 per barrel and a carbon intensity of 0.1 kg per barrel. This is probably one of the most profitable and robust projects in the company’s history,” says Margareth Øvrum, executive vice president for Technology, Projects and Drilling of Equinor.

The capital expenditures for the project are estimated at NOK 7.8 billion, helping extend the productive life of the Troll field beyond 2050.

“The Troll oil and gas field is in a class by itself globally. The plan for development and operation for the next phase of the Troll development submitted today is highly important both to the future value creation for Norwegian society, but also to ensuring future gas deliveries to Europe,” says Øvrum.

“The Troll operations have generated great value for the whole society. Since it came on stream in 1995 the Troll field has generated an estimated NOK 1,400 billion in revenues, equivalent to NOK 175 million per day in average. In the future we estimate that Troll will create even greater value,” says Gunnar Nakken, Equinor’s senior vice president for Operations West.

The expected future value creation from Troll is estimated at NOK 1,650 billion.

A large share of the Troll cashflow goes to the Norwegian State through taxes, and the State’s direct financial interests. The Troll field has thus added more than NOK 1,000 billion to the State revenues.

Gas to Europe

“The further development of Troll will also strengthen Norway’s ability to supply Europe with gas. The gas from Troll will ensure reliable, profitable and carbon-efficient gas supply equivalent to the consumption of 50 million households in Europe for 30 years in the future,” says Nakken.

The annual export volume from Troll is estimated to 8 % of EU’s gas consumption.

The gas is produced on the Troll A platform, which is electrified. The production therefore generates very low CO2 emissions. The gas is piped to Kollsnes, where it is cleaned, dried and compressed before being transported to Europe in the Zeepipe pipelines.

The development of the Troll field has also been important to the development of the oil and gas industry, particularly in Norway. The development of Troll Phase 3 will have a very high Norwegian content, estimated at approximately 70%.

Equinor will today sign contracts within marine installations and subsea facilities worth a total of approximately NOK 750 million with the companies Allseas, Nexans and Deep Ocean.

Earlier this year the partnership awarded contracts for subsea facilities and the construction of a new processing module on the Troll A platform to Aker Solutions.

Press conference at 10:00 CET – at Equinor’s office at Sandsli, Bergen.

A press conference will be held in connection with the submission of the PDO for Troll Phase 3. Entrance at 09.45 hrs. in the main reception at Equinor’s office on Sandsliveien in Bergen.

  • Troll partners: Equinor (30.58% - operator), Petoro (56%), Norske Shell (8.10%), Total E&P Norge (3.69%), ConocoPhillips Skandinavia (1.62%)
  • The Troll field consists of two reservoirs: Troll West and Troll East. The gas in Troll East is produced on the Troll A platform and piped to the Kollnes terminal. The thin oil zone in Troll West is produced on the Troll B and Troll C platforms and piped to the oil terminal at Mongstad.
  • Troll is Norway’s biggest gas producer, with enormous reserves still left in the ground. After more than 20 years on stream, about 65% of the gas has still not been recovered.
  • Troll has also been Norway’s biggest oil producer for the past five years.
  • The annual energy production from the Troll field is equivalent to about three times the annual Norwegian water power production.
  • Due to the enormous resources, development and production must be planned in three phases:

    – Phase 1 is the gas in Troll East, which resulted in Troll A, the Kollsnes gas processing plant and the associated infrastructure
    – Phase 2 is the oil in Troll West, which resulted in the Troll B and C platforms and associated infrastructure.
    – In Phase 3 the gas cap over the oil column in Troll West will be produced, at the same time as the oil production continues.

  • A general development plan for the gas in the Troll field has been developed, which implies that new wells and new infrastructure will probably be installed on the field also in the future. This is described in the PDO for phase 3 of the Troll development.
  • In 2017 the Troll partnership chose a subsea solution tied back to the Troll A platform as a concept for Troll Phase 3. The subsea concept includes the construction and installation of two subsea templates, drilling of 8 production wells, laying of a 36-inch pipeline and installation of a new processing module on the Troll A platform.
  • The development is powered from shore.
  • Aker Solutions has been awarded the contracts for the delivery of subsea facilities and construction of the processing module.
  • The Troll Phase 3 project extends the plateau production for gas from the Troll field by about 7 years, and the expected productive life by about 17 years.
