Catenary coiled tubing (CT) services from Baker Hughes let you conduct effective well interventions even when small platforms prevent placing CT equipment and operations on the topsides.

Our proven catenary CT services place the CT reel, pumping equipment, and other ancillary equipment onto nearby, smaller floating vessels or catenary barges. This eliminates the need to lift CT equipment onto a platform with limited deck space. As a result, offshore wells that were previously inaccessible to conventional CT equipment can undergo efficient interventions and be brought back to profitable production.


Ensure effective well cleanouts

Catenary CT services have been successfully deployed using the Sand-Vac™ cleanout system with a specially designed concentric reel and string for an intervention on four offshore wells in Asia Pacific. High sand production blocked access to the producing zones in the lower completion, thus shutting in the wells for years.

But with a wireless catenary CT unit connected to the platform from a nearby barge, the Sand-Vac and CCT solution recovered more than 7 metric tons from the four wells—with no safety incidents or CT-related downtime. Post-intervention, the operator experienced a 185% increase in expected daily production from the four wells.
