Casing Float Shoe, Differential Fill-Up
Can-Pro Downhole's Differential Fill-Up Float Shoe is equipped with a differential valve. This controls the differential filling of the casing during the running operation. The greater the differential pressure across the valve, the larger the control port in the diaphragm opens to allow fluid to enter the casing.
This type of filling action reduces running time of casing and reduces surge pressure on formations. This product is available in 5 1/2“ to 20 ” sizes and any special sizes can be provided upon request
