Is This The End Of Another North Sea Gas Field?

Is this the end of another North Sea Gas field? A question being asked as offshore operator Maersk Oil issues an official notice on the giant Tyra.

The official notice was issued today in relation to the cessation of the Tyra East and Tyra West platforms; part of Denmark’s biggest gas field and often regarded as the nation’s equivalent of the UK’s Brent field or Norway’s Statfjord.

End Of Another North Sea Gas Field?

Maersk Oil’s notice states: ‘production from Tyra East and Tyra West in the Danish North Sea will cease on 1 October 2018, if an economically viable solution for continued operations is not identified during 2016.’

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.

Unstable Structures

The two assets, located in the Danish sector of the North Sea, have been in operation for over 30 years; with the operator noting that, apart from having to deal with the fields ageing infrastructure, the reservoirs are continuing to suffer subsistence.

Maersk Oil have stated that over the last 15 years, DUC has spent more than DKK 1 billion (US$153 m) on reinforcing the structures to prolong production.

Tough Decision

“Together with our partners in DUC we are now evaluating long term economically viable solutions for recovery of the remaining resources,” said Managing Director for Maersk Oil Denmark, Martin Rune Pedersen.

“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,”

The Tyra Field

The Tyra field is operated by Maersk Oil on behalf of the DUC, a partnership between A.P. Moller – Maersk (31.2%), Shell (36.8%), Nordsøfonden (20%) and Chevron (12.0%).
