A degradable compound, which may be used as a ball sealer and as an fluid loss additive for use in the oil and gas industry is disclosed. The compound comprises a particular composition of matter and injection molding technique that provides a ball sealer which will dissolve in stimulation or wellbore fluids after stimulation operations are complete. In a similar manner the compound may be used as a fluid loss additive which enhances the fracture filter cake and will dissolve completely after use in fracturing operations. Used as a ball sealer, the surface of the ball sealer softens slightly assuring a solid seal between the ball and the casing perforation. The pure composition when dissolved into wellbore fluids does not pose a hazard and has excellent dispersion in aqueous based wellbore fluids. The same composition, may be combined with fiber-glass to manufacture a high temperature ball sealer.

Injection molded degradable casing perforation ball sealers fluid loss additive and method of use

A degradable ball sealer for use in the oil and gas industry is disclosed. The ball seat comprises a particular composition of matter and injection molding technique that provides a ball seal which will dissolve in stimulation or wellbore fluids after stimulation operations are complete. In use, the surface of the ball sealer softens slightly assuring a solid seal between the ball the and the casing perforation. The composition when dissolved into wellbore fluids does not pose a hazard and disperses well in aqueous based wellbore fluids. The same composition, made into a larger ball, may be used as a tubing sealer for pressure testing.
