Seeking cheaper interventions

September 30, 2003, 01:10 CEST

A campaign has been launched by Statoil to qualify new technology for cheaper and more efficient subsea well maintenance on the Norwegian continental shelf (NCS).

The MSV Regalia rig operated by Prosafe is due to carry out interventions in four underwater wells on three Statoil-operated fields during October.

Along with FMC Kongsberg Subsea and Maritime Well Service as well as Prosafe, the group has devoted much effort to qualifying light intervention for various types of subsea well on the NCS.

“Success in introducing this type of technology will be highly significant for operating costs and production life,” says Øivind Reinertsen, senior vice president for the Tampen business cluster.

“In that way, it will help to improve the recovery factor from subsea-completed developments on the NCS.”

MSV Regalia arrived on Statfjord North in the North Sea on 27 September for a production well workover before moving to Visund and Åsgard in the North and Norwegian Seas respectively.
