    Western Well Tool set a record for the longest distance travelled in an open-hole section during an acid stimulation and Production Logging Tool (PLT) run. The operator’s objective was to utilize coiled tubing instead of a drilling rig to perform the stimulation and PLT run in a 28,203-ft-MD extended-reach water-injector well with 5,986 ft of horizontal 61/8-in. open hole. A window at 22,217 ft was used to exit the 7-in. casing and create the sidetrack. Simulations indicated that lock-up of the coiled tubing would occur before reaching the window. The company used its hydraulically powered IT470 tractor to aid in stimulating the lateral from total depth back to the casing window. While running in hole, lockup occurred at 21,980 ft inside the casing.
