Abstract
A method and a system for injecting multiple tracer tag fluids into the wellbore are described. The method includes determining multiple injection concentrations of multiple respective tracer tag fluids, determining an injection sequence of the tracer tag fluids into a wellbore, and injecting the tracer tag fluids into the wellbore according to the injection concentrations and the injection sequence. The tracer tag fluids include synthesized polymeric nanoparticles suspended in a solution. The synthesized polymeric nanoparticles are configured bind to a wellbore cutting. The synthesized polymeric nanoparticles are configured to undergo a thermal de-polymerization at a respective temperature and generate a unique mass spectra. The injection sequence includes an injection duration determined by a depth interval of the wellbore to be tagged by the synthesized polymeric nanoparticles and an injection pause to prevent mixing the multiple tracer tag fluids in the wellbore.
