TCO's Self-Calibrating Cycle-Open Toe Valve uses pressure cycles applied at surface to open the valve, and there is no time limit on the duration of these pressure cycles or the casing pressure test. Once the predetermined number of cycles has been reached, the valve will open allowing hydraulic access to the formation/reservoir.
The ideal applications are cemented or open-hole, horizontal wells that require pressure integrity throughout the casing installation followed by communication/circulation ability at the toe of the well once the casing string is at the required depth and stimulation begins.
