C-2 Knockout Isolation Valve
The C-2™ Knockout Isolation Valve is designed to protect the formation from well hydrostatic pressure and resulting fluid loss after gravel packing. It is a single-acting (one-time) valve for use in single-zone completions or above the lower zone in multiple-zone completions. The valve will automatically support well hydrostatic pressures while the crossover tool is being pulled from the well and the completion seals are being run.
The valve contains a frangible flapper valve held open by the washpipe during gravel packing. In this position, normal crossover tool manipulations can be performed and fluid circulation paths are unaffected. When the crossover tool is pulled from the packer, the washpipe will slide freely through the valve. As the end of the washpipe comes through the valve, the flapper will swing to its seat, sealing off the ID of the liner.
The C-2 Knockout Isolation Valve may be used with the Isolation Tool H48758. Refer to Unit 5855 for information on this tool.
