The SpinCat line of downhole rotary nozzles from StoneAge are speed-controlled thru-tubing wash tools that can be used in a wide range of well-intervention applications with a variety of routine chemicals and solvents for rapid wellbore cleaning. Common applications include jetting out hydrates and ice plugs, descaling and acid washes, paraffin and asphaltene cleaning and post-frac proppant and fill clean-outs. They can be used as an alternative to motor-mills in post-cement and liner cleanup jobs. With proper care and maintenance, the tools can remain in service for many years. 866/795-1586; www.downholecleaning.com.
