A well is completed by cementing a casing string in place in the well. A jetting tool assembly is run into the casing string on a tubing string. The jetting tool assembly engages a sliding sleeve of a casing valve and slides the sliding sleeve to an open position uncovering a plurality of housing ports in the casing valve housing in which the sleeve is received. Then, disintegratable plugs are hydraulically jetted from the housing ports to communicate a subsurface formation adjacent the casing valve with an interior of the casing string. Preferably, prior to opening the sleeve and hydraulically jetting the plugs, residual cement is drilled from the casing string, then further residual cement is hydraulically jetted from the casing valve, and then the casing valve is backwashed by reverse circulation.
