Stab-in Casing Float Collar And Float Shoe API or As required

The Stab-In Float Collar & Shoe presents an enhanced approach for cementing large diameter casing. This method involves directly stabbing the Drill Pipe into the Float Shoe or Collar, allowing for cement to be pumped through the drill pipe until returns reach the surface. To ensure proper placement, a wiper dart can be utilized to displace the cement to the bottom of the Drill Pipe. Subsequently, the drill pipe is lifted, circulated, and withdrawn from the hole.

Furthermore, the use of large plugs becomes necessary to separate the cement from the mud, requiring subsequent drilling to remove both the plugs and any cement present in the casing. The Stab-In Float Collar & Shoe is specifically designed for cementing large diameter casings that are lowered using drill pipe. The unique characteristics of this casing string necessitate special considerations during the cementing process, primarily due to the high displacement volume associated with larger diameters.
