Abstract
A method comprises obtaining or providing a treatment fluid comprising a gellable agent; an aqueous carrier fluid; at least one polymer comprising one or more ortho-dioxy arylene units; a crosslinking agent; and placing the treatment fluid in a subterranean formation. In some embodiments, the aqueous carrier fluid comprises produced and/or flowback water. In some embodiments, the aqueous carrier fluid comprises high total dissolved solids, including multivalent salts or both monovalent and multivalent salts.
