The PCT Pressure Controlled Tester valve, operated by annulus pressure, is the downhole valve used to control formation flows and shut-ins for applications that do not use the IRIS Intelligent Remote Implementation System. The PCT valve must be run in conjunction with either the hydrostatic reference tool or the PORT Pressure Operated Reference Tool, either of which traps a reference pressure inside the PCT valve.
The two distinct sections of the PCT valve are the ball valve seal section and the hydromechanical operator section.
The versatility of the PCT valve can be enhanced by installing a hold-open (HOOP) module that holds the ball open when the annulus pressure is bled off. The HOOP module allows wireline to be run through the ball or circulation through the ball valve when the packer is not set.
Operating pressures for the PCT valve vary with depth but are usually between 6.95 and 10.34 kPa [1,000 and 1,500 psi] applied annulus pressure.
