ABSTRACT:
A method and apparatus for sealing a tool for use in a wellbore is provided. The seal is configured to be disposed in a tool comprising a ported sliding sleeve and a ported housing. The tool may be actuable between a closed and an open position. The seal is configured so that one side of the seal acts as a flow restrictor to protect the other side of the seal from damage during actuation of the tool under pressurized conditions.
