Abstract: A service tool that may be inserted into a tubular, the service tool includes an anchoring system. The anchoring system includes a body having a first end, a second end, and an opening extending along a portion of the body between the first end and the second end and a gripping assembly housed within and coupled to the body. The gripping assembly may anchor at least a portion of the service tool to the tubular, and the gripping assembly includes a plurality of anchor arms disposed within the opening and that may move relative to the body. The anchoring system also includes an actuator disposed within a central bore of the body and coupled to the gripping assembly. The actuator may apply a first axial input force in a first direction and a second axial input force in a second direction opposite the first direction to the gripping assembly, At least a portion of the gripping assembly translocates relative to the body in the first direction in response to the first axial input force to position the plurality of anchor arms in a radially expanded anchoring configuration, and the portion of the gripping assembly translocates relative to the body in the second direction in response to the second axial input force to position the plurality of anchor arms in a radially contracted configuration.
