Single & Double Valve Float Collar


Float Collar acts as a back-up valve to the one located in the Float Shoe. All Float Collars are fitted with NeOz ‘Genora ’ valve.

It acts as a landing point for casing wiper plugs. The Float Collar allows the contaminated cement to be captured in the shoe track instead of being pumped in the annulus.

The pressure holding capability of a float collar when a plug bumps against it is referred to as bump pressure. The pressure from the annulus on the back side of the valve is called the back pressure. The bumping confirms that the displacement is complete. The ‘Genora’ valve and the cement around it are capable of withstanding long periods of circulation.
