Engineering and offshore services provider Claxton has deployed a new modular conductor system to aid the rigless recovery of seven abandoned wells on the Norwegian Continental Shelf.
The ‘WellRaizer’ system has been developed by the company to allow the recovery of oil and gas conductor pipe and casing of up to 36 inches in diameter, without the use of a jack-up rig or platform-based drilling derrick.
Claxton’s research and development manager Matt Marcantonio said: “With the launch of WellRaizerTM Claxton is now able to bring severance and recovery all under one roof. We believe this capability is a first of its kind for the industry and means we can offer a full solution rather than just a one-off service to our customers.”
The system has a safe working load lifting capacity of up to 300 metric tonnes, and can recover pipe in 40ft lengths.
The technology can also facilitate safe systems of work procedures, for example by providing a safe area for technicians during the deployment of cutting systems used in drilling and pinning operations.
