Abstract

The present invention, in one embodiment, discloses a whipstock system having an orientation device; a flexion member releasably secured to the orientation device; co-acting lower and upper body members, the lower body member interconnected with the flexion member; a connecting bar which connects the upper and lower body members permitting the upper body member to move downwardly with respect to the lower body member while preventing separation of the two body members; and a concave member secured to and above the upper body member. In one preferred embodiment, one or more movable pawls on the connecting bar move to engage surfaces on one or both body members to prevent upward movement of the upper body member with respect to the lower body member, or conversely movement of the lower body member downwardly away from the upper body member; and movement of the one or more pawls in contact with both body members also forces the two body members apart further stabilizing the system in a tubular. Also disclosed is a setting or installation tool with a mandrel rotatable in an upper housing, the mandrel secured to a lower housing, so that torque or torsion is not transmitted through the tool. Also disclosed is a toggling connection member which permits a concave member to be pushed and then to move upwardly to pivot to a desired position.
