Completion locator assembly

A completion system for use within a cased wellbore, the completion system comprising:

• a well string;
• a downhole tool coupled to the well string;
• and
• an alignment assembly coupled to the well string and proximate the downhole tool, the alignment assembly comprising:
• an outer assembly;
• an inner assembly positioned at least partially within the outer assembly, and including a plurality of channels;
• a locator releasably coupling the outer assembly to the inner assembly and shaped to engage with a shoulder of the casing to align the downhole tool with a location along the casing, the locator including guide pins engaged with corresponding channels of the plurality of channels and configured to permit relative axial movement between the outer assembly and the inner assembly, and limit relative rotational movement between the locator and the inner assembly;
• and
• a compensator assembly positioned about the inner assembly configured to limit the relative axial movement between the outer assembly and the inner assembly.

A method of positioning a well string within a wellbore, the method comprising:

• running a tubing string comprising an alignment assembly into the wellbore;
• engaging a locator of the alignment assembly with a shoulder of a casing positioned within the wellbore to align a downhole tool with a location along the casing, the locator including guide pins engaged with corresponding channels in an inner assembly configured to permit relative axial movement between an outer assembly and the inner assembly, and limit relative rotational movement between the locator and the inner assembly;
• releasing the inner assembly of the alignment assembly from the outer assembly of the alignment assembly to allow the relative axial movement between the outer assembly and the inner assembly;
• and
• limiting the relative axial movement between the outer assembly and the inner assembly via a compensator.
