## Abstract

A location connector connects a first tubular to a second tubular, and includes a cylindrical main body extending in a longitudinal direction. An outer surface extends around a circumference of the main body, and an inner surface faces the central bore of the main body. A first connector is on a first end of the main body and is configured to attach to the first tubular. A second connector on an opposite second end of the main body is configured to attach to the second tubular. A female profile is provided on the inner surface, and includes a plurality of grooves for selective engagement with a discrete complementary profile comprising one or more protruding members of a downhole tool. Each of the grooves comprises a no-go shoulder that prevents movement of the tool in one direction, and each of the grooves permits clocking movement of the tool in an azimuthal direction.
