Beschreibung
Zusammenfassung:	A method of treating a well includes placing a first stream comprising a carrier fluid, a polymerizable small molecule cationic clay control monomer, and an optional polymerization initiator into a fracture in a clay-containing subterranean formation, allowing the small molecule cationic clay control monomer to at least partially adsorb to a portion of the surface of the clay, and polymerizing at least a portion of the adsorbed clay control monomer. A clay stabilizing fluid includes an aqueous base fluid, a polymerizable small molecule cationic clay control monomer, and a polymerization initiator.
