Abstract
A method of treating a multi-zoned subterranean formation with composites having well treatment agents is disclosed. The well treatment agent treated in each zone is distinguishable. At least a portion of the well treatment agent is released from one of the composites into the well or formation. The formation of undesirable contaminants may be inhibited or prevented in the well or in the formation by the release of the well treatment agent from one or more of the composites. The well treatment agent also serves as a tracer. When fluid transported from the formation or well is collected, the source of the transported fluid may be determined by comparing a chemical or physical parameter of the well treatment agent with a working set of known taggants.
