Abstract:
An assembly for removing debris and/or conducting a wellbore operation may include a mandrel, a sliding sleeve rotationally coupled to the mandrel, and a flushing sleeve coupled to the sliding sleeve. A releasable connection may temporarily prevent axial movement between the sliding sleeve and the mandrel. A downhole tool may be coupled to the mandrel to conduct the wellbore operation. The flushing sleeve may be hydraulically actuated to an extended position ahead of the downhole tool. A method of removing debris from a wellbore and conducting a wellbore operation may include lowering an assembly into the wellbore, supplying pressurized fluid into the wellbore using the assembly to remove debris from the wellbore, and moving a downhole tool to a position where at least a portion of the downhole tool is disposed outside of the assembly to conduct the wellbore operation.
