When you’re cleaning out your well or milling composite frac plugs miles below the surface, you can either hope for the best or guarantee the best possible outcome with the HydroPull™, the most powerful friction- breaking tool on the market.
The technology is sophisticated but the concept is simple – if you need to move a garden hose up a grassy hill, would you push it or pull it? A pushed hose will buckle almost immediately – the same physics apply to plug milling and wellbore cleanouts during long horizontal runs deep below the surface. Use of the HydroPull™ tool saves operators countless hours of rig time by pulling the BHA in the well at 20 ft/min or more and by delaying the onset of helical buckling and lockup.
The HydroPull tool incorporates a cycling valve that momentarily interrupts the flow to create water-hammer pressure pulses inside coiled or jointed tubing used in horizontal well interventions.
The water-hammer effect generates traction forces that pull the tubing into the well at 20 ft/min (6 m/min) or more.
These periodic pulses also vibrate the tubing, which reduces friction drag and extends the lateral reach of the tubing by delaying the onset of helical buckling and lockup.
The HydroPull tool is typically run above a downhole motor for milling applications. The tool is fully tunable for various impact levels and custom applications.
A proprietary software program is available for HydroPull tool job planning. The software evaluates circulating pressures in the well and horizontal reach capabilities based on a set of input parameters. The program also calculates pump pressure requirements, the transport of sand and cuttings in the horizontal and vertical sections of the well, predicted lockup, and the rate at which the tool will pull tubing into the well. More information about the Software’s capability is described in the Tempress Software Brochure in the Software section.
