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, on a first end of the main body, 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.

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.

An anchoring tool for positioning a downhole tool within a wellbore conduit is described herein. The anchor tool uses replaceable blades having protrusions that are configured to align with corresponding grooves in an anchor sub receptacle that is located at a known position along the wellbore conduit. The blades of the anchor tool are configured to move radially relative to the anchor tool body until the anchor tool is aligned with a compatible anchor sub. When the anchor tool and the compatible anchor sub are aligned, the protrusions of the anchor tool blade extend into the grooves of the anchor sub receptacle and a locking mechanism within the anchor tool inhibits further radial movement of the blades. A downhole tool connected to the anchor tool can therefore be positioned at a precise location relative to the known location of an anchor sub receptacle.
