Float shoes have long been regarded as standard equipment for installing and cementing casing strings. They serve the crucial role of regulating fluid flow into and out of the casing through one-way check valves. These valves automatically close when pressure from below exceeds that from above, permitting flow from above while blocking flow from below. Positioned at the bottom of the casing string, the float shoe facilitates the casing’s passage through the open hole during installation until it reaches the final setting depth.
