Abstract:
A sliding valve for opening one or more fluid ports in a piping string, having a valve body and a sliding sleeve in a longitudinal bore thereof. The valve body has one or more fluid ports in an uphole portion thereof. The sliding sleeve is movable in the valve body between an uphole closed position closing the one or more fluid ports and a downhole open position opening the ports. The sliding sleeve has a longitudinal bore for receiving a collet, and/or a stop ring and/or a protective sleeve. The stop ring forms a stop shoulder for preventing downhole movement of the collet relative to the sliding sleeve. The protective sleeve presents ingress of cement or detritus into an annular region between the bore of the valve body and the sliding sleeve thereby ensuring the sliding sleeve is free to move so as to open said fluid ports.

Claim (Index 8):
A sliding valve for opening one or more fluid ports in a production string, comprising:\n a valve body having a longitudinal bore, the valve body comprising said one or more fluid ports on an uphole portion thereof and a ratchet structure on an inner surface of a downhole portion thereof; and a sliding sleeve received in the longitudinal bore of the valve body and movable between an uphole closed position closing the one or more fluid ports and a downhole open position opening the one or more fluid ports; wherein the sliding sleeve comprises:\n a sleeve body having a longitudinal bore, the sleeve body comprising a ratchet structure on an outer surface of a downhole portion thereof, the ratchet structure of the sleeve body engageable with the ratchet structure of the valve body for locking the sliding sleeve when the sliding sleeve is at the downhole open position; and \n a protection sleeve downhole to the sleeve body, at least a coupling portion of the protection sleeve received by the sleeve body for coupling the protection sleeve to the sleeve body; \n wherein at least when the sliding sleeve is at the closed position, the protection sleeve and the valve body form an annulus therebetween; and wherein the protection sleeve substantially overlays the annulus from the longitudinal bore of the valve body.
