Patent number: 9255220Abstract: 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.Type: GrantFiled: July 11, 2014Date of Patent: February 9, 2016Inventors: Olusegun Matthew Falana, Edward C.
