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

Long gun string and partially set plug stuck at 19,328 ft

During stage 6 of a 30-stage hydraulic fracture campaign a 71-ft gun string was accidently pumped off the cable. At 19,328 ft in the horizontal well, the fish—including a partially set bridge plug—was too deep to be reached with coiled tubing. A conventional uninstrumented tractor was pumped down but engagement of the fish could not be confirmed. If the fish had been engaged, without reverse-tractoring capability the conventional tractor would not have been able to move it without exceeding maximum safe pull on the cable. The operator needed a reliable, measured approach to recovering the gun and plug without having to resort to bringing in a rig.

Tractor deployment of controlled, measured axial force

The anchor and high-force linear actuator tool combination of ReSOLVE instrumented wireline intervention service reliably delivers multiple extensions and retractions while continuously reporting the measured displacement and applied force to validate operations. The tool’s anchor has the largest range for pulling tools in the industry, to well IDs of 6.7 in, and applies up to 150,000 lbf of anchoring force. The innovative low-stress anchor grips minimize the tubing imprint while maximizing traction. Once anchoring is confirmed to the surface, the linear actuator can be extended or retracted multiple times to apply a large, controlled force of up to 45,000 lbf to the specific well component.

Deployment of ReSOLVE service on the UltraTRAC all-terrain wireline tractor brings the highest tractor force available in the industry to the job. The UltraTRAC tractor readily conveys large payloads in challenging borehole conditions and across high-angle, extended-reach wells to simplify and streamline wireline operations to reduce cost, time, and risk.
