A method includes setting a tubular above a bottom of the well. The tubular having a float shoe attached to a distal end of the tubular and a controllable port penetrating a wall of the float shoe. The method further includes isolating a section of the annulus, opening the controllable port, and pumping cement through the controllable port into the section of the annulus to cement the annulus of the well.

A tapered nose tool includes a housing, a retrievable tapered nose disposed in the housing and retrievable from the housing, and a mechanically shiftable sleeve. The mechanically shiftable sleeve is shiftable with a shifting profile disposed in the housing. The sleeve anchors the nose in the housing in a first position and releases the nose from the housing in a second position.

A rupture disc assembly and a float tool incorporating the rupture disc assembly is disclosed. The rupture disc assembly may include a rupture disc assembly comprising a rupture disc, an upper tubular portion and a lower tubular portion, and a securing mechanism for holding the rupture disc between the upper and lower tubular portions. A float tool for creating a buoyant chamber in a casing string may include the rupture disc assembly and a sealing device for sealing the lower end of the casing string, the buoyant, sealed chamber may be created there between. In operation, applied fluid pressure causes the rupture disc to move downward. The rupture disc may be shattered by contact with a surface on the lower tubular portion. Full casing internal diameter may be restored in the region where the rupture disc formerly sealed the casing.

A casing string includes an uphole section, a downhole section, and a sealed chamber that is fluidically isolated from the uphole and downhole sections. The sealed chamber extends between the uphole and downhole sections. The casing string further includes a tube that is disposed within the sealed chamber and that fluidically connects the uphole and downhole sections to provide a fluid flow path that extends past the sealed chamber and through the casing string.

A wellbore assembly includes a wellbore string configured to be disposed within a wellbore. The wellbore assembly also includes a float collar coupled to a downhole end of the wellbore string. The float collar includes a housing, a check valve, and a sleeve. The housing includes a fluid outlet. The housing defines a fluid port that extends through a wall of the housing. The check valve is disposed within the housing between the fluid port and the fluid outlet. The sleeve is coupled to the wall of the housing uphole of the check valve. The sleeve moves, based on pressure changes of the fluid in the float collar, with respect to the wall of the housing thereby either exposing the fluid port and opening a fluid pathway from the bore to an annulus of the wellbore, or covering the fluid port and blocking the fluid pathway.

A single trip liner running and tie-back system includes a liner string to case a formation, a polished bore receptacle installed in a liner hanger, and a tie back casing string to tie back the liner string to a wellhead. The tie back casing string is fit with a seal assembly comprised of a no-go stopper, and the seal assembly of the tie back casing string is anchored inside the polished bore receptacle of the liner hanger to run the liner string and the tie back casing string in tandem.
