Low density ball sealers for use in well treatment fluid diversions
Patent
·
OSTI ID:6433013
A ball sealer for use as a diverting agent when treating a well having a perforated casing. The ball sealer is sized to plug a perforation and has a density less than the treating fluid. The ball sealer comprises a material, such as syntactic foam or polymethylpentene. The ball sealer is also preferably provided with a protective covering material. After some of the treating fluid has been injected into the well, the ball sealers are injected and carried by the fluid flow down to the perforations where they seat and divert the further injection of treating fluid through the remaining open perforations.
