Abstract
A sliding valve has a valve body, a sliding sleeve received in a longitudinal bore of the valve body, and a collet receivable in a longitudinal bore of the sliding sleeve. The valve body has one or more fluid ports on an uphole portion of the sidewall thereof. The sliding sleeve is 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. The collet comprises a metal portion about an uphole end of the collet, and a ball seat having a ball-seat surface radially inwardly sloped from uphole to downhole at an acute slope angle with respect to a longitudinal axis of the collet. The metal portion is radially outwardly expandable under a radially outward pressure to form a metal-to-metal seal at the interface between the collet and the sliding sleeve when the collet is received in the sliding sleeve.
