Abstract
There is provided a method of stimulating a formation within a wellbore that is lined with a wellbore string, the wellbore string including a port and a flow control member, wherein the flow control member is displaceable relative to the port for effecting opening and closing of the port. The port is opened by displacing the flow control member in response to an applied pressure differential across a sealing interface. The port is closed by displacing the flow control member with hydraulic hold down buttons prior to removing the sealing interface and effecting pressure equalization.
