## Abstract

Provided is an inner string and a well system. The inner string, in one aspect, includes an inner tubular including a sidewall having a thickness (t3), the inner tubular having 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 inner string, according to one aspect, further includes a weighted swivel located around the inner tubular, the weighted swivel including an orientation slot, the orientation slot configured to align with the orientation port to provide a pressure reading indicative of a relative location of the inner tubular to the weighted swivel.
