API Standard Single/Double Valve Casing Float Shoe
Product Description
A float shoe is used in the drilling of oil and gas wells. It is a single cylindrical piece that performs the functions of both a float collar and a guide shoe. Its main purpose is to guide drilling equipment to the bottom of the well without snagging, like a guide shoe. It also contains a check Valve to allow fluids to pass in only one direction, like a float collar.

6. Application
Float equipment 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.
7. Characteristics:
1) For float shoe, the rounded nose profile helps guide casing string.
2) The valve is made with phenolic material and molded with high strength concrete. Both of the valve and concrete are easily drillable with PDC or rock bits.
3) High strength design ensures excellent performance for flow endurance and back pressure holding.
4) Saves considerable running-in time with automatically fill up.
5) For non-rotating float collar, the special non-rotating groove design ensures corresponding cementing plugs drilled out quickly.
