ABSTRACT:
A downhole tool for use in a well bore comprises an onboard navigation system for determining the location of the tool within the well bore, wherein the tool is moved along at least a partial length of the well bore via an external force. A method of locating a downhole tool in a well bore comprises deploying the tool along at least a partial length of the well bore via an external force, and self-determining the location of the tool without receiving communications from the surface. In an embodiment, the tool is a well bore zonal isolation device.
