Abstract: A stabilizer system articulates at least one blade independently of an extendable blade for a through tubing mill. The stabilizer can be actuated with flow, pressure or set down weight. A piston responds to flow or pressure from the surface and an elongated member can cam out the stabilizer with set down weight on the extendable blades.

Abstract: A bottom hole assembly comprises a milling tool and associated drive motor with a shifting tool that is capable on deployment to selectively grab, shift and release from sliding sleeves when the bottom hole assembly is removed from the subterranean location. The shifting tool is preferably protected from the returning flow of cuttings to avoid erosion or clogging from the cuttings being circulated to the surface. The shifter tool can be of a known design to enable the milling of ball seats or entire plugs in the same trip as the operation of the sliding sleeve valves associated with the treatment operation so that the well can then be in position to commence production or injection once a suitable string and service packer are set in position. Typically the sleeves are open for the treatment and then closed after milling as the bottom hole assembly is removed.
