An actuation device for well operations can include a tubular body including a plurality of key slots, a threaded shaft disposed within the tubular body that rotates relative to the tubular body and is fixed axially relative to the tubular body, an actuator disposed within the tubular member that moves axially relative to the tubular body, wherein the actuator includes a ramp portion and a threaded neck portion that engages with the threaded shaft such that when the threaded shaft rotates, the actuator moves axially relative to the tubular body, and a plurality of keys, each disposed in one of the plurality of key slots and in operative communication with the ramp portion such that as the actuator moves axially relative to the tubular body, each key is urged radially outwardly from the tubular body.

Actuation devices for well tools

A downhole tool that includes a tubular member having a first interior passageway, wherein the first interior passageway defines a first surface having a first internal diameter and a second recessed surface having a second internal diameter that is greater than the first internal diameter. The downhole tool also includes a protective sleeve engaged with the second recessed surface, wherein the protective sleeve has a second interior passageway that defines a third surface having a third internal diameter that is substantially equal to the first internal diameter such that the third surface is substantially flush with the first surface. In one embodiment, the protective sleeve is dissolvable upon contact of a fluid having predetermined composition or predetermined temperature such that the sleeve dissolves to expose the recesses formed in the latch assembly.
