Claim Text:
1. A system for setting a completion tool within a wellbore comprising: a mandrel being placed in an interior of the wellbore and having a generally tubular shape, said mandrel being comprised of an indentation on an exterior and a pressure inlet through a side wall of said mandrel, wherein said indentation is comprised of sliding surfaces at both ends of said indentation, said sliding surfaces extending from a bottom of said indentation to said exterior; an inner sleeve of the completion tool, having a generally tubular shape and an interior surface facing said mandrel and an exterior surface facing outward, wherein said inner sleeve is comprised of an aperture through a side wall of said inner sleeve and a pressure conduit through said side wall of said inner sleeve; a piston of the completion tool, being mounted on said inner sleeve and facing said exterior surface of said inner sleeve, said piston being comprised of a locking surface at one end, said locking surface facing said exterior surface of said inner sleeve; an outer sleeve of the completion tool, having a generally tubular shape, an interior side wall facing said piston and an exterior sidewall facing outward, said interior side wall forming a gap between said outer sleeve and said inner sleeve, said piston being housed within said gap and being slideable longitudinally along said interior side wall of the outer sleeve and said exterior surface of said inner sleeve; and a dog means having a mandrel interface, piston interface on an end opposite said mandrel interface, a first face, and a second face on a side opposite said first face, said dog means being removeably engaged to said mandrel, said inner sleeve, and said piston, wherein, in a first position, said mandrel interface abuts against said indentation of said mandrel, said piston interface abutting said locking surface of said piston, said dog means being friction fit between said locking surface of said piston and said indentation of said mandrel, and wherein, in a second position, said outer sleeve and said inner sleeve and said one end of said piston form a chamber within said gap, said dog means being housed within said chamber, said mandrel interface being released and separate from said indentation, said piston interface being released and separate from said locking surface of said piston.
