Embodiments of this invention relate to a composition and a method for tailoring the rheology of a fluid for use in the oil field services industry including forming a fluid comprising a tetrakis(hydroxyalkyl) phosphonium salt and a polymer, and exposing the fluid to a temperature of about 20° C. to about 200° C., wherein a viscosity is observed that is at least about 5 percent different than if no salt were present. Embodiments of this invention also relate to a composition and a method for tailoring the rheology of a fluid for use in the oil field services industry including forming a fluid comprising a tetrakis(hydroxyalkyl) phosphonium salt and diutan and/or guar and/or guar derivatives and/or a combination thereof, and exposing the fluid to a temperature of about 20° C. to about 163° C., wherein a viscosity is observed that is at least about 5 percent lower than if no salt were present. Embodiments of this invention also relate to a composition and a method for tailoring the rheology of a fluid for use in the oil field services industry including forming a fluid comprising a tetrakis(hydroxyalkyl) phosphonium salt and xanthan, and exposing the fluid to a temperature of about 20° C. to about 200° C., wherein a viscosity is observed that is at least about 5 percent higher than if no salt were present.
