Abstract

A downhole tool cleans debris from a subsea well with nozzle assemblies that selectively deploy from the tool. The nozzle assemblies are in fluid communication with an annulus of a drill pipe on which the downhole tool is mounted, so that fluid pumped into the drill pipe discharges from nozzles provided with the nozzle assemblies. The nozzle assemblies are strategically situated so that when deployed, a stream discharged from nozzles on the assemblies clears debris from a surface between a casing hanger and wellhead housing. The nozzle assemblies are coupled to an annular piston coaxially set on the tool; and sliding the piston axially along the tool deploys the nozzle assemblies. Axially spaced apart ports extend radially through the tool to opposing faces on a head of the piston. Blocking one of the ports with a ball dropped down the drill pipe moves the piston and deploys the assemblies.
