  • Patent number: 6715560
    Abstract: A selectively released well tool anchor has a tubular wicker shoe cage and a tubular setting sleeve in sliding assembly over a tubular mandrel. The wicker shoe cage confines a plurality of independent wicker shoes. The tubular setting sleeve has a conical slip face that is loosely meshed with the shoe cage by a plurality of collet fingers extended from the conical slip face into meshed engagement with detents in the shoe cage. The collet fingers are secured within the detents for well run-in by calibrated shear fasteners. An axial translation of the setting sleeve toward the shoe cage by shearing the fasteners displaces the wicker shoes outwardly for inside wall penetration. The wicker shoes are disengaged from the wall by axial translation of the cage from the sleeve to engage mutual abutment faces on the cage and shoes.

The wicker shoe cage confines a plurality of independent wicker shoes. The tubular setting sleeve has a conical slip face that is loosely meshed with the shoe cage by a plurality of collet fingers extended from the conical slip face into meshed engagement with detents in the shoe cage. The collet fingers are secured within the detents for well run-in by calibrated shear fasteners. Slip faces on the several wicker shoes are aligned with the conical slip face to effect a radial displacement of the wicker shoes by an axial translation of the setting sleeve relative to the shoe cage. However, no relative axial translation may occur until sufficient axial compressive force between the shoe cage and setting sleeve is imposed to shear the calibrated fasteners.
