Abstract: Methods and systems are provided for favorably altering the chemomechanical properties of subterranean formations using treatment fluids comprising surfactants and halide salts. Methods for treating formations comprise the steps of introducing a chemomechanical treatment fluid into the formation and allowing the treatment fluid to interact with the formation to alter its petrochemical properties in various ways. Depending on the application, the chemomechanical treatment fluid may comprise a base fluid, a halide salt and an amphoteric or nonamphoteric surfactant where the surfactant is dissolved in the base fluid at a concentration below its critical micelle concentration. Applications of use involving the chemomechanical treatment fluids include treatment operations, secondary recovery operations, drilling operations, and any other operation that would benefit from the formation property modifications described herein.
