Abstract
A well construction method, and corresponding apparatus, in which a drilled bore () is lined with a plurality of successively smaller diameter sections of bore-lining tubing includes at least one casing () and at least one liner (). The well construction method comprises: drilling a final section of a bore () to intersect a hydrocarbon-bearing formation (); providing a shoe () at a distal end of a liner and a running tool () at a proximal end of the liner, and coupling an inner string () between the shoe () and the running tool (); running the liner () into the final section of the bore () such that the liner extends into the hydrocarbon-bearing formation (); pumping a settable material () from surface (), through the inner string (), and through the shoe () to at least partially fill an outer annulus () surrounding the liner (); and retrieving the inner string () and the running tool ().
