Abstract
A method to perform zonal inflow analysis of a well. The method includes disposing a chemical tracer module in each perforation zone in the well to interact with produced fluid to produce a zonal signature that uniquely identifies the corresponding perforation zone, obtaining a production flow at a wellhead that has zonal contributions of the produced fluid from the perforation zones, measuring, in the production flow and using a chemical analysis panel at the Earth's surface, a concentration of the zonal signature of each perforation zone, determining, using at least the chemical analysis panel and based on the concentration of the zonal signature of each perforation zone, a respective measure of each zonal contribution, and facilitating, based on the respective measure of each zonal contribution, a production operation of the well.
