Maersk Oil has reached an agreement with the Danish government providing terms to enable the Danish Underground Consortium (DUC) partners to advance a full redevelopment plan for the Tyra field facilities toward a final investment decision by yearend.
Pending FID, production from Tyra is now expected to stop in December 2019, instead of the previously planned permanent shuttering date of October 2018, and then restart in March 2022 on completion of redevelopment (OGJ Online, Jan. 3, 2017). The full redevelopment program requires a resequencing of engineering activities from the decommissioning and partial redevelopment scenario outlined in December 2016.
Tyra field has experienced subsidence of the chalk reservoir leading to the platforms sinking around 5 m in the last 30 years, reducing the gap between the sea and the platform decks. A full redevelopment would restore current infrastructure, including the gas processing hub and five surrounding satellite fields such as Harald and Valdemar.
Maersk adds that redevelopment also could enable future production of oil and gas from the DUC license area as well as third-party projects. Since 1984, Tyra has processed 90% of the Denmark’s gas production.
Tyra field is operated by Maersk Oil on behalf of DUC, a partnership of AP Moller–Maersk with 31.2% interest, Royal Dutch Shell PLC 36.8%, Danish state-run Nordsofonden 20%, and Chevron Corp. 12%.
