Abstract
A shoe for use with a casing or liner string includes: a tubular body; a nose: mounted to an end of the tubular body, and having: a plenum formed therein, a front port extending longitudinally from the plenum to an exterior of the nose, and a side port extending transversely from the plenum to the exterior of the nose; and a valve repeatedly shiftable between a deployment position where the front port is open and the side port is closed and a cleaning position where the front port is closed and the side port is open. The valve shifts to the deployment position in response to forward flow through the shoe being less than a threshold flow rate. The valve shifts to the cleaning position in response to the forward flow through the shoe being greater than the threshold flow rate.
