Abstract
An encapsulated scale inhibitor comprises: at least one scale inhibitor, wherein the at least one scale inhibitor is in the form of particulates; and an encapsulating material, wherein the encapsulating material at least partially encapsulates the at least one scale inhibitor, wherein the encapsulated scale inhibitor is capable of complete degradation. In one embodiment, a method comprises: providing a treatment fluid comprising a plurality of scale inhibitor particulates that comprise at least one scale inhibitor and a self-degrading encapsulating material that at least partially encapsulates the scale inhibitor; and introducing the treatment fluid into a well bore penetrating at least a portion of the subterranean formation.
