Claim 0:
1. A method for tracer tracking for control of flow control devices on injection wells, the method comprising:
executing, by at least one computer processor, a reservoir model using a plurality of numerical tracers to obtain a plurality of output values for at least one producer well, wherein each of the plurality of numerical tracers comprises a numerical or alphanumeric identifier (ID), wherein:
each of the plurality of numerical tracers is assigned to at least one corresponding injection flow control device comprised in a plurality of injection flow control devices of at least one injection well of the injection wells, wherein the plurality of numerical tracers comprises first and second numerical tracers assigned to respective first and second injection flow control devices of the plurality of injection flow control devices of a first injection well of the injection wells, wherein the first and second injection flow control devices are independently controllable based on the respective first and second numerical tracers to inject fluid into respective first and second geological layers; and
the at least one corresponding injection flow control device comprises a flow control valve;

calculating, from the plurality of output values at the at least one producer well, a set of volume fractions for the plurality of injection flow control devices;
solving, by the at least one computer processor using the set of volume fractions, an optimization problem to obtain a flow control device parameter;
storing the flow control device parameter in storage;
generating on a display device, using the flow control device parameter, an aperture setting for the at least one corresponding injection flow control device; and
initiating, using the aperture setting, adjusting of an aperture associated with the at least one corresponding injection flow control device.
