Abstract
An assembly for cleanout of scale buildup from a wall of a hydrocarbon well. The assembly is configured to be deployed and operated under pressure without the requirement of coiled tubing to deliver cleanout fluid. The assembly may include a plug for sealing against the wall of the well immediately above the location of scale buildup. A cleanout tool, such as a jetting nozzle may be coupled to the downhole side of the plug. Thus, fluid and pressure may be provided to the well uphole of the plug. In this manner, the plug may direct the fluid to the jetting nozzle to achieve cleanout of the scale buildup.
