OSLO, NorwayRepsol has submitted a new plan for development and operation (PDO) for the Yme field in the Norwegian North Sea, with an estimated cost of more than NOK8 billion ($953 million). Start-up is slated for 2020.

The company plans to use existing facilities that were installed on the field during an earlier development phase in 2007, with oil produced through the leased jackup drilling and production facility,Mærsk Inspirer, which will be modified and adapted to operate on Yme.

The Norwegian Petroleum Directorate (NPD) assesses the field’s future recoverable oil resources at 65 MMbbl.

Over the next few weeks, the NPD will review the proposals and assess the associated financial, technical, and resource-related risks.

Statoil originally produced Yme, in a remote location in the far eastern Norwegian sector, from 1996 to 2001. The field was then shut down and the facilities removed, as operations appeared to be no longer profitable.

Talisman Energy later submitted a new PDO, but the newly constructed jackup could not be used after structural faults were identified at the field location, prior to start-up. It was therefore removed in 2016 without initiating production.

Repsol, Talisman’s new owner, plans to re-use nine wells and to drill six new wells, producing through horizontal wells with pressure support from water injection and water-alternating-gas injection. All produced water and all gas will be re-injected into the reservoir.

The existing facilities at Yme comprise a caisson, a subsea oil storage tank, pipelines and a connection between the Gamma and Beta structures, a manifold and subsea template with three slots on Beta, a subsea loading system for oil from the storage tank, and wells on both Gamma and Beta.
