A liner is inserted in the casing and is preferably expanded into sealing
contact with the mounting location on the casing. After expansion a
cement retainer positioned at the bottom of the expanded liner and the
sliding sleeve located either above the mounting location of the liner in
the casing shoe or in the liner below the mounted top section allow
cement to be delivered outside the expanded liner and the displaced
wellbore fluid to return into the casing through so that the liner can be
cemented. The cement retainer can be delivered with either the liner or
the expansion tools to allow expansion and cementing in a single trip. A
shifting tool can be run on the expansion string to actuate the sliding
sleeve and if necessary to allow for cement to be pumped from the drill
string into the annulus through the sliding sleeve. The cement retainer
can be milled out in a separate trip.
