ESEAL™ HIGH-PERFORMANCE LINER RESTORES WELLBORE INTEGRITY; MAXIMIZING RECOVERABLE RESERVES
CHALLENGE
An Operator in West Virginia’s Marcellus Basin had a horizontal well with approximately 3,200 feet of damaged casing and connections that needed to be repaired prior to completing the primary fracking operation. The Operator had previously attempted to repair the interval with an external patch without success. The external patch did not provide the internal pressure integrity to allow for the planned frac job with controlled isolation and injection rates at controlled entry points.
