An alignment assembly for use with a well string having a downhole tool to be positioned within a cased wellbore. The alignment assembly may include an outer assembly, an inner assembly positioned at least partially within the outer assembly, a locator, and a compensator. The locator may releasably couple the outer assembly to the inner assembly and be shaped to engage with a shoulder of the casing to align the downhole tool with a location along the casing. The compensator may be coupled to the outer assembly, positioned about the inner assembly, and configured to limit relative axial movement between the outer assembly and the inner assembly.

Completion locator assembly

A well system includes an annular barrier separating the tubing-casing annulus into an upper annulus and a lower annulus and a barrier valve coupled with the annular barrier, the barrier valve permitting one-way fluid communication from the upper annulus to the lower annulus.
