Wash Tool

The Wash Tool is used to inflate the External Casing Packer and for washing the Completion String, for example during an acid job. It features two opposing Swab Cups with a ported jacket pipe between them. For inflating the ECP the Wash Tool is run in conjunction with a Bypass Ballseat and a Swivel below.
In order to build up pressure between the Swab Cups a ball lands in the Bypass Ballseat and closes the inner string under the Wash Tool.
