Jette

On 19 May 2013, Aker BP started production on the Jette field. The production is now closed and field is shut-in. 

Jette is an oil field about six kilometres south of the Jotun in the central part of the North Sea. Water depth is 127 metres. Jette is developed with a subsea template with two producing wells tied-in to the Jotun A facility.

 

Production start-up at Jette

The development concept

In February 2012, the Norwegian authorities approved the Plan for Development and Operation (PDO) of Jette. The field has been developed with a subsea installation tied back to the Jotun B platform. The Jotun installations consist of a floating production facility with storage and offloading facilities (Jotun A), and a wellhead platform (Jotun B).

A number of modifications to Jotun B, in addition to minor modifications on Jotun A, were required in order to tie the two fields together. The chosen development concept enables future tie-up to additional wells. The well stream from Jette is mixed with the well stream from Jotun on Jotun B, and transported to Jotun A for further processing, storage and export.

Challenging drilling operation

The drilling of the production wells on Jette commenced in February 2012 and was completed in November. The well completion and installation of equipment on the seabed posed certain challenges. One of the two production wells collapsed during the drilling operation, resulting in the implementation of a new drilling plan. The adjustment entailed a significant increase of development costs, and the modified well path resulted in a reduction of the recoverable volume. Jette is the fastest developed field on the Norwegian shelf. It took Aker BP less than 21 months to start production after submitting PDO.
