摘要：
Internal breakers are given that break fluids viscosified with non-polymeric viscosifiers such as viscoelastic surfactants, inside formation pores. The breakers are polyols, for example natural and synthetic sugars, monoalcohols, and mixtures of the two. The sugars may be ketones and aldehydes. The sugars are also breaker aides for oxidizing agents used as breakers. Methods of using the breakers and breaker aides in oilfield treatment fluids are given.
