ENGINEERINGNET.EU -- Development of technology for increasing the recovery from operating fields is important for Norway’s Statoil. In the last year the company succeeded in increasing its average oil recovery rate from the operated fields from 49 to 50 percent.
In cooperation with the supplier industry, Statoil now has developed a new type of rig and well control system specially adapted to carry out well intervention and drilling operations in existing subsea wells.
The new rig type will not be purchased, but licensed from Aker Solutions in an eight-year contract with options for three times two years for the (category B) service. The estimated value of the contract is USD 1.9 billion.
The rig with associated integrated services is expected to reduce operating costs for well intervention by as much as 40%.
“This will be a very important part of the toolbox for increased recovery on the Norwegian continental shelf, making it possible to produce oil and gas that otherwise would be lost,” says Statoil executive vice president of Technology, Projects and Drilling, Margareth Ovrum.
The rig will be in service during 2015.
