摘要： Certain carrier-free treatment particulates comprising solid treatment chemicals and methods for their formation and of their use in subterranean formations are provided. In one embodiment, the methods comprise: providing a plurality of carrier-free N treatment particulates comprising at least one solid treatment chemical and a coating at least partially disposed around an outer surface of the solid treatment chemical; and introducing the plurality of carrier-free treatment particulates into a well bore penetrating at least a portion of a subterranean formation, wherein the plurality of carrier-free treatment particulates is at least partially consumed in the subterranean formation to create a residual porosity in the portion of the subterranean formation.

摘要： Certain particulates of encapsulated treatment chemicals, and methods of and systems for their use in subterranean formations, are provided. In one embodiment, the methods comprise: providing a plurality of treatment particulates, at least one of which comprising a polymer matrix that comprises and/or encages at least one treatment chemical and a coating disposed around an outer surface of the polymer matrix; and introducing the treatment particulates into a well bore penetrating at least a portion of a subterranean formation.
