A method of treating a subterranean formation includes providing a treatment fluid comprising particles of at least one of a hydrolysable in-situ acid generator and a hydrolysable in-situ chelating agent generator. The treatment fluid is combined with a carrier fluid and is introduced into a subterranean formation. The particles are placed in fractures or microfractures where, upon the hydrolyzing of the acid or chelating agent generator, etching of the faces of the fractures or microfractures occurs.
