    摘要: A fluid breaking composition including an effective amount of an alkali chlorite and/or hyperchlorite is disclosed, where the composition reduces a viscosity of a polymer viscosified fluid to a desired low value at down hole conditions within a time period coincident with a formation stimulation time, generally between about 30 minutes and 195 minutes. Methods for making and using the breaking composition are also disclosed.

    摘要: Defoamer compositions are disclosed and methods for making and using same, where the defoamer has universal applicability at low concentrations. The defoamer compositions include between 40 vol. % and about 80 vol. % distilled water (other waters may be used instead), 10 vol. % and about 30 vol. % of silicon anti-foam agent and between about 10 vol. % and about 30 vol. % of active silicon anti-foam agent. The defoamer compositions are used in amount of less than or equal to 200 ppm in all foamed downhole fluid systems.
