Tyra gas field

Tyra field is the largest gas condensate field in the Danish sector of the North Sea. Its facilities process more than 90% of the gas produced in Denmark.

Tyra gas field

Tyra gas field was discovered in 1968 and brought into production in 1984. The field consists of Tyra East and Tyra West production centres, which are linked to 5 unmanned satellite fields, Tyra Southeast, Harald, Valdemar, Svend and Roar.

The Tyra gas field features 111 oil and gas wells, along with 106 well slots for future drilling under the redevelopment project.

The Tyra field is one of the fields in the Sole Concession Area managed by the Danish Underground Consortium (DUC), a joint venture involving Total, Noreco and Nordsøfonden. Total is operator of the field with a share of 43.2%, while Noreco holds a share of 36.8% and Nordsøfonden 20%.

The seabed below the Tyra platforms has sunk nearly 5 meters since 1984. As a result, the gap between the sea and the Tyra platforms’ decks was reduced. This reduction ultimately means redevelopment is necessary to keep both crew and equipment safe, as well as keep production efficient.

Production of gas from the Tyra field was suspended in September 2019. Most of the installations at the field were dismantled in June 2020, and the 2 giant process facilities were scheduled for removal in August 2020. This marked a major milestone in the project. The plan is to install new facilities at the Tyra field in 2021, which would allow production to resume in 2022.

The Tyra Redevelopment consists of 3 main elements: Removal and decommissioning of the prior Tyra platforms, reuse and 13 meters extension of the current jackets at 6 platforms that will have new topsides and a totally new process platform and a new accommodation platform.

When back in operationin in July 2022, Tyra will reach peak production of 60,000 boe/d. It is estimated that the facility will produce enough gas to supply 1.5 million Danish homes at peak production, in addition to providing support for the Danish economy.

With the use of new technology and modernized working processes Tyra’s operating efficiency is expected to increase, and at the same time reduce CO2 intensity by 30%.
