A downhole tool includes an inner mandrel including external threads. The downhole tool also includes a lock ring positioned around the inner mandrel. The lock ring includes a plurality of segments that are circumferentially-offset from one another. Each segment includes an inner lock segment portion including internal threads that are configured to engage the external threads of the inner mandrel. Each segment also includes an outer lock segment portion that is positioned radially-outward from the inner lock segment portion. Each segment also includes a plurality of shear elements extending at least partially radially-through the inner lock segment portion and the outer lock segment portion to couple the inner lock segment portion and the outer lock segment portion together. The shear elements are configured to shear in response to a predetermined force to decouple the inner lock segment portion from the outer lock segment portion.

Shearable lock mechanism for storm packer anchor

An anchor-packer assembly includes a packer having a slips assembly and a seal. The slips assembly and the seal are radially expandable so as to engage a surrounding tubular. The assembly also includes an anchor coupled to the packer. The anchor includes a slips assembly and is configured to transmit a first torque and a first axial force to the packer, to set the packer. The anchor is configured to be actuated from an anchor running position in which the slips assembly thereof is retracted, to an anchor set position, in which the slips assembly thereof is expanded radially outward, in response to a second torque and a second axial force, and the anchor in the anchor set position is configured to prevent an uphole-directed force on the packer from releasing the slips assembly of the packer from engagement with the surrounding tubular.
