Abstract
A method may comprise introducing a first traceable solid particulate into a first formation zone of one or more subterranean formations, wherein the first traceable solid particulate may comprise a first soluble tracer coated onto a first solid particulate. The method may also comprise introducing a second traceable solid particulate into a second formation zone of the one or more subterranean formations, wherein the second traceable solid particulate may comprise a second soluble tracer coated onto a second solid particulate, wherein the second tracer and the first tracer may have a different chemical identity. The method may further comprise recovering produced fluid from the one or more subterranean formations and monitoring concentrations of at least the first soluble tracer and the second soluble tracer in the produced fluid.
