Suspended Well Abandonment Tool (SWAT)
Claxton has abandoned over 100 suspended category subsea wells in the North Sea for our customers. These category 2 wells all required a shallow cement plug spanning all the casing annuli.
Our experience with these wells directly informed the development of our multi-award winning Suspended Well Abandonment Tool – SWAT.
SWAT is deployed from the back of vessel or through a moonpool, landed on the wellhead and then used to carry out casing perforation and placement of the required cement plugs in the well. The wellhead can then be severed using SABRE abrasive cutting tool and recovered using the Claxton wellhead recovery tool.
Benefits of SWAT:
- Deployed from a vessel, removing the need a drilling rig
- A one-stop solution to place the final cement barrier across all annuli
- Deployed as part of a total suspended subsea well abandonment package
- Proven across multiple successful offshore campaigns
Award Winning:
The first tool of its type, SWAT holds the Queen's Award for Innovation in the UK, and the prestigious Petroleum Institute Platinum Award for Innovation.
