Paper Number: SPE-168297-MS
... Abstract Water hammer tools (WHTs) are used in coiled tubing (CT) operations for postponing a potential helical lock-up and running deeper into the hole. By rapidly opening and closing a valve in the tool, pressure pulses are created and the axial vibrating force is overcoming the friction...
