Abstract (en)
[origin: WO2011072367A1] A method for opening a port through the wall of a ported sub including: providing a hydraulically actuable valve to cover the port, the valve being actuable to move away from a position covering the port to thereby open the port; providing a removable pressure isolator that seals tubing pressure from accessing the valve; removing the pressure isolator from blocking access to the valve; increasing the pressure within the sub to move the valve towards a low pressure side, while the port remains closed by the valve; thereafter, reducing pressure within the sub; driving the valve to move it away from a position covering the port; and removing a portion of the pressure isolator to provide further fluid access through the ported sub.
