A ‘Completely Different’ Approach to Well Intervention

An annular well intervention solution is gaining traction as a means for operators to repair leaks and delay plugging a well.

Repairing leaks in a pressurized annulus has been problematic, but one solution is able to pass a wellhead and run into the annulus bore to allow leak remediation, fluid displacement and resin placement.

Expro’s Octopoda tool, deployed on more than a dozen projects, is intended to help operators economically regain their wells. In one recent deployment, the tool intervened to allow an inspection that gave an operator the information needed to decide whether to carry out a slot recovery on a well.

Dave Bowman, Expro’s vice president for business development, says the tool addresses the big issue of sustained casing pressure and cement leaks.
