FLOAT SHOE
The COMPLETION OIL TOOLS® Float Shoe consists of rounded profile from the bottom which is attached to the downhole end of a casing string. It contains NRV valve which prevents reverse flow. The Float Shoe also guides the casing towards the center of the hole to lessen the hitting rock ledges. It can resist the Back Pressure Up to 5000 psi.
The float shoe reduces hook weight. With controlled or partial fill-up as the string is run, the casing string can be floated into position, avoiding the need for the rig to carry the entire weight of the casing string.
FLOAT COLLAR
COMPLETION OIL TOOLS, Float Collar allow operator to maintain a constant fluid height inside the casing of a well. As fluid is allowed to enter through the bottom of the casing, the system maintains a constant differential pressure between the inside and outside of the casing at the floats to ensure constant fluid height within the casing. A spring-loaded valve in the fill-up unit regulates filling. When hydrostatic pressure outside the casing exceeds the spring tension, fluid is allowed to enter the casing; when pressure inside the casing combines with spring tension to exceed the pressure outside the casing, the valve closes.
