Float Collar And Float Shoe

The Non rotation Float Collar is run in a casing assembly, usually several joints above the Float Shoe.

It serves as an extra back pressure valve sealing against pressures from blow while running the assembly and after the cementing job.

Internal latch and valve are readily drillable. Its capability of back-pressure is over 25MPa.

Size:4 1/2″ to 20″

Non-rotating Float shoe attaches to the end of the casing string.Non-Rotating Float Collar attaches to one or two casing joints above Float Shoe and they are use to stop slurry from flowing back.

Non-rotating insert helps to engage the connecting plugs in it and locks the rotation when PDC drill bit is used.

1. PDC Drillable.
2. Inverted Poppet valve has greater strength.
3. Can withstand high temperatures & pressure.
4. Non-Metallic parts prevent damage to PDC Drill Bit
5. Controlled buoyancy-regulated by filling casing cum surface.
6. It is available in Single & Double Valve design.

In all applications ranging from close tolerance liners to full casing strings.

Float Collar Float & Shoe serves as the backbone of casing equipment used during primary cementing operations.It guides the casing to total depth and prevents contaminated mud from entering the casing. Also it provides a landing point for casing wiper plugs, reinforces the lower end of the casing string, and ensures greater accuracy of cement slurry displacement.
