Claim Text:
1. An anchoring system comprising: a housing having a radial opening therein; a piston disposed within the housing having a bore therethrough receptive to flow, the piston being axially movable relative to the housing; a seat disposed on the piston configured to allow pressure differential to build across the piston when a plug is seated against the seat; a slip in operable communication with the piston such that movement of the piston in a first axial direction relative to the housing causes movement of the slip in a first radial direction relative to the housing to anchor the anchoring system to a structure and movement of the piston in a second axial direction allows the slip to move in a second radial direction that allows unanchoring of the anchoring system; and a sleeve in operable communication with the housing and the piston, configured to cause movement of the piston in the second axial direction when moved in the second axial direction relative to the housing, the sleeve being movable in the second axial direction relative to the housing in response to mechanically pulling the sleeve in the second axial direction wherein the slip is engaged with the piston and the housing such that movement of the piston in the second axial direction urges the slip to move in the second radial direction and wherein the engagement of the slip with at least one of the piston and the housing is through a dovetail arrangement.
