10. A method, comprising:
circulating a drilling fluid into a wellbore during a drilling process to form the wellbore in one or more subterranean formations;
circulating a portion of uniquely identifiable particles from one of a plurality of containers into the drilling fluid during the drilling process;
circulating a return drilling fluid from the wellbore during the drilling process, the return drilling fluid comprising the drilling fluid, a plurality of cuttings from at least one of the one or more subterranean formations, and at least one of the portion of the uniquely identifiable particles;
separating the drilling fluid from the plurality of cuttings from at least one of the one or more subterranean formations and the at least one of the portion of the uniquely identifiable particles;
capturing at least one image of the separated plurality of cuttings and the at least one of the portion of the uniquely identifiable particles;
determining, based on the image, a depth of the at least one of the one or more subterranean formations;
determining, based on the image, an amount of the portion of the uniquely identifiable particles from the one of the plurality of containers in the portion of cuttings from at least one of the one or more subterranean formations;
comparing the determined amount of the portion of the uniquely identifiable particles with an expected amount of the portion of the of uniquely identifiable particles; and
based on the determined amount being less than the expected amount, circulating an increased portion of uniquely identifiable particles from the one of the plurality of containers into the drilling fluid during the drilling process.
