Case Study: a leading operating company recovers a 71-ft gun string and partially set plug with SLB's ReSOLVE service on UltraTRAC tractor

ReSOLVE Service on UltraTRAC Tractor Recovers 71-ft Gun String and Partially Set Plug from 19,328 ft

SLB worked with a leading operating company in the Williston Basin to recover a 71-foot gun string and partially set bridge plug from 19,328 feet in a horizontal well after conventional uninstrumented fishing attempts failed. The fish was too deep for coiled tubing access, and a standard tractor could not be confirmed on the fish or safely move it without risking excessive cable tension.

SLB deployed the ReSOLVE Service on the UltraTRAC tractor, using the anchor and high-force linear actuator to apply controlled, measured axial force while reverse tractoring maintained safe cable loads. The system successfully recovered the gun string and plug by retracting the actuator 68 times to add 30,000 lbf of force, moving the fish past perforations and casing collars and allowing the job to be completed without a rig.
