1. An inner string, comprising:
an inner tubular configured to extend at least partially within a seal surface of an outer tubular, the inner tubular including a sidewall having a thickness (t1); and
an orientation port extending entirely through the sidewall to provide fluid access from an interior of the inner tubular to an exterior of the inner tubular, the orientation port configured to align with an orientation slot in the outer tubular that it is configured to engage with to provide a pressure reading indicative of a relative location of the inner tubular to the outer tubular, the orientation slot being a longitudinal orientation slot having a length (l) and a width (w), wherein the length (l) of the longitudinal orientation slot is greater than the width (w).
