A contract worth some NOK 80-100 million for coiled tubing services on the Norwegian continental shelf has been awarded by Statoil to Schlumberger.
This assignment will run for three years, with options for two renewals of two years each.
It covers the provision of personnel and equipment for all coiled tubing work on the NCS, other than drilling with coiled tubing and operations from special intervention vessels.
Coiled tubing is used primarily for production well workovers and in completing newly-drilled wells.
The technique involves running a long tube, normally coiled on a drum, into the well under pressure. This saves time and avoids damaging the reservoir.
“Coiled tubing represents a cost-effective way of increasing and maintaining production from our fields,” explains Jan Eric Lode, discipline leader at Statoil for this technology.
“The work embraces the use of perforating guns, plugging, logging and workovers.”
