Abstract
Systems and methods of the present disclosure relate to control of a downhole tool via at least one radio isotope. The radio isotope(s) is pumped from the surface to contact an isotopic analyzer of the tool. The isotopic analyzer reads the isotope and directs the tool to perform a specific action(s) in the wellbore based on the type of isotope read by the analyzer.
Claims14
A method comprising:
- pumping at least one type of radio isotope into a wellbore;
- contacting a tool with the at least one type of radio isotope at a downhole isotopic analyzer;
- reading the at least one type of radio isotope with a downhole isotopic analyzer of the tool to determine a specific type of the at least one type of radio isotope;
- and
- triggering operation of the tool in response to identification of the specific type of the at least one radio isotope.
