Rapid Intervention of 5.5in Casing Remediation Using a Wireline-Deployed Alloy and Resin Patch Technology

Maintaining casing performance throughout the life of a well is critical to safe and efficient hydrocarbon production. In unconventional developments, repeated stimulation cycles and high flow velocities increase the likelihood of casing damage, particularly across perforated or previously squeezed intervals. Traditional remediation techniques such as cement squeezes, casing patches installed with workover rigs, or coiled tubing deployed solutions can be time consuming, costly, and operationally complex. As operators seek to minimize nonproductive time and reduce exposure to live well operations, rigless intervention technologies have become increasingly attractive. Wireline deployed casing remediation systems offer the ability to address damaged intervals with a smaller surface footprint, reduced logistics, and faster execution. This paper presents a field case in which a wireline deployed alloy and resin patch was used to remediate a 5.5 in casing interval, preserving internal diameter and enabling a rapid return to planned production operations.
