Cementing Foam Wiper Ball
Foam technology has been developed that substantially improves the wiping and fluid separation possible when performing cementing pumping operations. Natural rubber foam matrix materials are used in the fabrication of wiper balls that can be used for numerous pumping operations using mono-ID and multi-ID bores over a temperature range of 40°F (4°C) through 302 °F (150°C).
Applications for foam wiper balls include mechanical tubular wiping, fluid separation & drill pipe clan out, and it can be used in conjunction with conventional plugs / darts to improve wall cleaning.
The foam ball sizes and application parameters are listed in below table.
