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.

Real-time zonal inflow analyzer with closed-loop tracer system

A well system includes a wellhead arranged atop a wellbore, production tubing extending from the wellhead into the wellbore and thereby defining an annulus between the production tubing and an inner wall of a wellbore, and a plurality of fixed injection ports defined in the production tubing. The well system further includes a chemical injection system that includes one or more chemical conduits extending from the wellhead within the annulus and communicably coupled to the plurality of fixed injection ports and thereby placing the one or more chemical conduits in fluid communication with an interior of the production tubing, a chemical injection line in fluid communication with the one or more chemical conduits via the wellhead, and a pump arranged in the chemical injection line to convey one or more chemicals from the chemical storage tank to the production tubing via the one or more chemical conduits.
