Patent ID: 8342251

Claim:
A shoe for wellbore lining tubing, the shoe comprising: an outer tubular body adapted to be coupled to wellbore lining tubing, the outer tubular body having at least one flow port for fluid communication between the wellbore and an interior of the outer body; an inner body located within the outer tubular body and adapted to be coupled to fluid supply tubing located within the wellbore lining tubing for the flow of fluid through the tubular inner body into the wellbore; a flow diverter assembly being operable to be moved between a first position in which fluid flow from the wellbore to an annulus defined between the wellbore lining tubing and the fluid supply tubing is permitted, and a second position in which fluid flow from the wellbore to an annulus defined between the wellbore lining tubing and the fluid supply tubing is prevented; actuating means for actuating movement of the flow diverter assembly between its first and second positions, the actuating means comprising a seat adapted to receive a flow stemming member and a release mechanism for the flow stemming member; wherein the shoe is adapted such that, upon actuation, the flow of fluid from the fluid supply tubing into the wellbore is prevented until the flow diverter assembly is in its second position.
