Abstract
Systems and methods for monitoring and characterizing well bores, subterranean formations, and/or fluids in a subterranean formation using well evaluation pills are provided. In one embodiment, the methods comprise: introducing a well evaluation pill into a portion of a well bore penetrating a portion of a subterranean formation; allowing the well evaluation pill to interact with one or more components in the portion of the subterranean formation; detecting a change in the composition or properties of the well evaluation pill; and determining the presence of one or more components in the portion of the subterranean formation based at least in part on the detected change in the composition or properties of the well evaluation pill.
