Patent ID: 8360147

Claim:
An apparatus for obtaining feedback of the location of a well component comprising: a wellhead assembly with a bore; port leading through the wellhead assembly into the bore to provide a path for a fluid to flow into the bore from an external location; and a tool for performing an operation in a well comprising; an elongated stem, a body circumscribing the stem, a feedback member mounted to the stem, the tool moveable from a position so that an outer surface of the feedback member blocks the port, and a passage in the feedback member adapted to provide a path for fluid to flow from the port through the feedback member, wherein the passage in the feedback member has an inlet in the form of a circumferential groove on the exterior of the feedback member; and a pressure reading device adapted to establish pressure of the fluid, so that when the tool is moved to register the passage with the port, a pressure measured with the pressure reading device is less than a pressure measured with the pressure reading device when the outer surface of the feedback member blocks the port.
