Abstract
A method for operating a downhole tool. The method includes moving an instrument through a wellbore, and the instrument includes a first non-acoustic transponder that is adapted to detect identification codes. An identification code detected from at least one second non-acoustic transponder is compared to a reference code. The at least one second non-acoustic transponder is attached to an emplaced structure in the wellbore, and the comparison is performed when the instrument moves by the at least one second non-acoustic transponder. The downhole tool is then operated if the identification code matches the reference code.A downhole tool operation system including at least one first non-acoustic transponder emplaced in a wellbore and adapted to communicate an identification code. At least one second non-acoustic transponder is adapted to move through the wellbore, and the at least one second non-acoustic transponder is adapted to detect an identification code when moving by the at least one first non-acoustic transponder. A processor is coupled to the at least one second non-acoustic transponder and is adapted to compare the identification code to a reference code and operate the dow…
