Detailed Product Description

API Oiflfield casing float collar and float shoe Description

 

A rounded profile float shoe with an integral check valve attached to the bottom of a casing string prevents reverse flow, or U-tubing, of cement slurry from the annulus into the casing or flow of wellbore fluids into the casing string as it is run. The float shoe also guides the casing toward the center of the hole to minimize hitting rock ledges or washouts as the casing is run into the wellbore.


A float collar is installed near the bottom of the casing string. Cement plugs land on it during the primary cementing operation, thus retaining inside the casing a small portion of the cement slurry that may have become contaminated as the top plug scrapes the inside of the casing. It is similar to a float shoe; often both are used for redundancy. The internal check valves may be flapper type or spring-loaded balls.

 
API Oiflfield casing float collar and float shoe Features
  • Reduce strain on the derrick while guiding casing past ledges and slough zones in the hole;
  • Provide a landing point for bottom and top cementing plugs 
  • Provide a backpressure valve to prevent cement from flowing back into the inner diameter of the casing after the cement has turned the corner into the annulus and the top plug has been bumped.
