ABERDEEN, UKCoretrax claims to have saved a UK North Sea operator more than £0.5 million ($0.66 million) during a well abandonment campaign in the UKCS.

The contractor, which is supporting decommissioning of 11 wells, helped saved 28 hrr rig time on one well alone. Work should continue through March 2019.

Coretrax used its CX-Tubing hanger to secure the completion tubing before deploying its CX-RTP (retrievable test packer) and CX-SVE cement retainer to assist restoration of annular cement.

The CX-Tubing hanger is designed to hang up to 400,000 lb of tubing weight and to cut out the time-consuming process of tubing disposal, said to cost operators £0.25 million ($0.33 million) or more per well and up to 30 hr rig time.

It is also said to eliminate the need to pull tubing back to the surface which requires manual handling in a high-risk area of the rig, known as the Red Zone.
