Abstract: A downhole tool position adjustment assembly for locating a tool downhole comprising a mandrel coupled to a housing via an extend-retract mechanism. A controller communicatively connected to the extend-retract mechanism, wherein an application executing within the controller, is configured to control the extend-retract mechanism. A communication system, communicatively coupled to the controller, is configured to receive a command signal from an operator at a surface location. The extend-retract mechanism moves the mandrel relative to the housing in response to a control signal received from the controller in response to the command signal received by the communication system.

Abstract: A method of performing real-time position sensing includes conveying a tool attached to a tubular string in a borehole. The tool includes a position sensing sub, and the position sensing sub includes sensing devices. The method further includes recording measurements taken by the sensing devices. The method further includes determining based on the measurements, a position along the borehole of a particular portion of the tubular string. Data from sensing devices having a higher priority overrides collecting data from sensing devices having a lower priority. The method further includes transmitting the position wirelessly.
