Float collar and Float shoe
Float shoe is attached on the casing bottom ,.Float collar is installed on the casing and up the float shoe. Like float shoe, it also provide buoyancy to the casing string when it's lowered, reducing the load on the drilling rig.
Float shoe is attached on the casing bottom ,and provide buoyancy while casing string lowered, reducing the load of the drilling rig.
The round nose guides the casing away from ledges and obstructions in the well bores as the casing is lowered. A build-in check valve provides buoyancy to the casing string also prevents cement from re-entering the casing after it is displaced.

Floating shoes and hoops can replace guide shoe, casing shoe.
It can be used not only for general technical casing and reservoir casing, but also for deep Wells, ultra-deep Wells and special process Wells.
The internal structure of float shoe and float hoop is basically the same, except that the upper and lower ends of float hoop body are API casing threads.
