Aker to supply well intervention services to Statoil

17th April 2012

Technology providers team up with Norwegian energy giants to provide new drilling units

New devices are being developed to unlock reserves in areas such as Norwegian continental shelf where vast hydrocarbon reserves can be found

Oilfield expert, Aker Solutions has entered a long-term agreement with Statoil to provide a full range of heavy well intervention and light drilling services on the Norwegian continental shelf.

The contract period is for eight years, with options for three further two-year periods.


Contract value for the initial eight-year period is approximately USD 1.9bn. Work will be performed from a new build Category B well intervention rig, which will be owned and operated by Aker Solutions' subsidiary Aker Oilfield Services.

The company’s “ability to bundle technology and expertise has proven to be a competitive advantage when bidding for this contract. It will involve deliveries from our oilfield service arm, engineering, drilling technologies, subsea and well intervention services," said Øyvind Eriksen, Aker Solutions, executive chairman.

"The Norwegian continental shelf is recognised world-wide for its high recovery rates. With the Cat-B initiative, Statoil and their partners is taking a quantum leap by taking a fully integrated approach to increasing recovery rates from subsea wells. We are pleased to support Statoil in the development of this new technology and innovative business model," added Eriksen.

The Category B (Cat-B) rig is a semi-submersible unit designed for year-round well intervention. It will provide a full range of heavy well intervention and light drilling tasks including through-tubing rotary drilling, wireline, coil tubing, high pressure pumping, well testing and cementing services as well as ROV operations. It will operate in water depths up to 500 metres.

Well intervention services are carried out in an oil or gas well to maximise production and increase the recovery rate of oil and gas. Well intervention has traditionally been performed from fixed platforms. In more recent years, specially equipped ships or rigs have been developed to undertake the same type of service on subsea wells where recovery rates have been much lower.

The subsea well intervention system, for example the infrastructure between the rig and the seabed, is based on the technology solutions developed for Aker Oilfield Services' deepwater well intervention vessel Skandi Aker.
