A new water-soluble perforation ball sealer has been developed and successfully used as a substitute for conventional ball sealers. They also can and have been used in situations where conventional ball sealers would not be an option due to the potential of creating undesired costly workover operations.
The introduction of a degradable or water-soluble ball sealer signifies a major breakthrough in ball sealer technology. This paper discusses the new ball sealer chemical and physical properties and development methodology. Laboratory testing techniques and methods are presented.
This paper focuses on the laboratory testing conducted during the development phase and the data generated to support proper application in the field. Also, the potential benefits of water-soluble ball sealers are presented along with examples of successful application in wells.
