FLOAT COLLAR (VE-96)

Float Collar is a component installed near the bottom of the casing string on which cement plugs land during the primary cementing operation. It typically consists of a short length of casing fitted with a check valve. This device may be a spring-loaded plunger valve, a flapper-valve type, a spring-loaded ball valve or other type. The check-valve assembly fixed within the float collar prevents flow back of the cement slurry when pumping is stopped. Without a float collar, the cement slurry placed in the annulus could U-tube, or reverse flow back into the casing. The greater density of cement slurries than the displacement mud inside the casing causes the U-tube effect.
