Abstract

Apparatuses and methods for an anti-preset and anti-reset mechanism for a retrievable packer are disclosed herein. These features may be used to prevent the packer from being actuated prematurely during deployment downhole and to prevent the packer from re-actuating during retrieval. An apparatus may include a mandrel, a slip assembly disposed about the mandrel, a collet member disposed about the mandrel and adjacent to the slip assembly, and a cover sleeve disposed about the mandrel and coupled to the collet member. A method for releasing a packer may include cutting a mandrel, sliding a cover sleeve and a collet member having a collet lug downhole with respect to the mandrel, applying force from the collet member to the slip assembly, disengaging the slip assembly from a well casing, and engaging an inner surface of the collet lug to a protrusion on the mandrel.
