Droppable object with locating system and pressure pulse telemetry actuator for use in a wellbore

A method for determining the location of a droppable object as it travels in a wellbore, comprising:

• deploying a droppable object in a casing string disposed in the wellbore, the casing string including a plurality of completion components, wherein the droppable object includes an integral locating system, the locating system comprising a sensor system and an actuator device;
• pumping a fluid behind the droppable object, causing the droppable object to travel through the interior of the casing string and past one or more of the completion components;
• detecting, by the sensor system, a completion component as the droppable object travels past the completion component;
• counting a number of detected completion components;
• generating a telemetry signal corresponding to detection of the completion component for receipt by a surface acquisition system, wherein generating the telemetry signal comprises activating the actuator device to apply a radially directed force against an inner surface of the casing string, thereby generating a pressure pulse, and wherein the telemetry signal is generated when the counted number of detected completion components exceeds a determined threshold;
• and
• determining, by the surface acquisition system, a location of the droppable object within the casing string based on the telemetry signal.
