ABSTRACT:
A method and apparatus are provided for selectively shifting a tool member in a subterranean well, such as a sliding sleeve of a ported element, which may be carried on a continuous length of remedial tubing, or other conduit into the well and insertable through a second conduit, such as production tubing. The apparatus comprises a cylindrical housing with a fluid passageway therethrough. Means are carried by the housing for selectively indicating proximity of the apparatus relative to the auxiliary tool, or ported member of a sliding sleeve. Actuating means are positioned by longitudinal manipulation of the first conduit, or remedial tubing, and movable into engaging position with a ported member, upon a first movement of the first conduit in a second direction to resist movement of the apparatus in the second direction. Normally retracted, selectively expandable shifting means are carried by the housing and movable to an expanded position by further movement of the first conduit in the second direction to move the shifting means into expanded position to interengage the movable means of the auxiliary tool, or ported member. Hydraulic means, including a piston, are activatable to drive the movable means of the auxiliary tool, thereafter, in one of opening and closing directions, or into actuating position, when the shifting means are in the expanded position. Releasing means are provided for moving the actuating means into disengaging position and for moving the shifting means thereafter into the normally retracted position, for retrieval of the tool to the top of the well.
