Abstract
Friction reducing compositions for use in well treatment fluids generally include an aqueous fluid; a polymeric friction reducer; and 3,5-dimethyl-1,3,5-thiadiazinane-2-thione. It has been found that the combination of the polymeric friction reducer; and 3,5-dimethyl-1,3,5-thiadiazinane-2-thione unexpectedly and synergistically increases friction reduction and inversion behavior, where applicable. Also disclosed are methods for the fracturing of a subterranean hydrocarbon bearing formation to stimulate the production of the hydrocarbons by injecting the friction reducing composition.
