Deployed liner system enables efficient repair of parted pipe

摘要

CT deployment and no drill-out requirement saves days of rig time while delivering the well to its full production potential. An operator completing a natural gas well in the Marcellus Shale of northeastern Pennsylvania encountered a casing integrity problem during the 12th stage in a planned 30-stage fracturing operation. Loss of wellbore integrity, which the operator suspected was caused by a leaking connection in the heel of the well, prevented completion of the remaining 18 stages.
