Conveyance of Coiled Tubing Tool Strings
Sakhalin Island, Russia
Job: 0401
Well Depth: 9,300 meters + TMD
2,600 meters + TVD
Problem: The conveyance of tool stings carrying perforating guns and production logging instruments to TMD beyond that of the coiled tubing helical lock-up point.
Solution: The WWT International Inc. Intervention Tractor, developing 8,500 lbs. of force and installed at the end of the coiled tubing, was able to deliver tool strings to the desired location on 5 runs into the well, accumulating over 4,300 meters of walking distance at up to 17 ft. per minute.
Problem: Operator tried unsuccessfully with competing tractors to perform well cleanout and remove composite bridge plugs to achieve target depth.
Solution: The WWT International CT Tractor was used successfully to convey the coiled tubing beyond lock-up, perform a balldrop and open up a circulation port at TD, and enable milling of composite bridge plugs left over from fracing operations.
