Maersk Oil, the Danish oil and gas company owned by the A. P. Moller-Maersk Group, has announced that it will cease production from its Tyra field in the Danish North Sea in October 2018 if an economically viable solution for its continued operations is not found during 2016.
The company says the Tyra facilities are approaching the end of their operational life due to a combination of more than 30 years of production and subsidence of the underground chalk reservoir, reducing the gap between the facilities and the sea.
The Tyra field is operated by Maersk Oil on behalf of the Danish Underground Consortium (DUC), a partnership between A.P. Moller – Maersk (31.2%), Shell (36.8%), Nordsøfonden (20%) and Chevron (12.0%). The field still holds significant gas resources that remain to be extracted, and over the last 15 years DUC has spent more than DKK 1 billion on reinforcing the structures to prolong production.
“Together with our partners in DUC we are now evaluating long term economically viable solutions for recovery of the remaining resources. As part of this, we will consider the terms under which a rebuild of the facilities could take place. The basis for a decision needs to be in place by the end of 2016 to ensure future production from the field,” says Martin Rune Pedersen, Managing Director for Maersk Oil Denmark.
Tyra is Denmark’s largest gas field and the facilities are the processing and export centre for all gas produced by the Danish Underground Consortium (DUC). More than 90% of Denmark’s gas production is processed through the facilities.
Tyra East and Tyra West are also the hub for a number of smaller facilities in the Tyra field, which will be part of the evaluation. This includes the neighbouring unmanned facility, Tyra Southeast, which was extended in 2015.
