UK: Coretrax, leading engineered service for wellbore clean and abandonment, has launched its CX-IST (Inflation Support Tool) to the oil and gas market, following a US$3m development investment.

The CX-IST significantly reduces rig time, offering substantial cost savings. It gives a positive indication that the cement will be set in the correct place before latching at the bottom of the work string, using a pre-installed landing sub. Once secure, pump pressure inflates the elastomer to seal the wellbore. The IST is then released by picking up the work string. The CX-IST creates a 100% wall-to-wall base for well cement or fluid. The operator can deploy as many ISTs as needed in the same or multiple zones without tripping the drill pipe in and out of the hole, providing significant operator time and cost reductions.

"This is a monumental success for Coretrax and a game changer for the entire industry," said Kenny Murray, managing director at Coretrax. "The team is passionate about the business and has worked tirelessly for three years, from initial stages, to produce an innovative product, which will benefit the oil and gas sector."
