Stab-in Casing Float Collar And Float Shoe API or As required
The Stab-In Float Collar & Shoe technique is a more effective approach for cementing large diameter casings. This method involves directly inserting the drill pipe into the Float Shoe or Collar, allowing cement to be pumped through the drill pipe until it reaches the surface. Subsequently, the cement is displaced to the bottom of the Drill Pipe using a wiper dart. To complete the process, the drill pipe is retrieved, circulated, and removed from the wellbore.
Furthermore, in addition to using large plugs to isolate cement from the mud, it is also necessary to drill out any cement in the casing. Notably, the Stab-In Float Collar & Shoe technique is uniquely suited for cementing large diameter casings that are lowered using drill pipe. This approach is essential when handling high displacement volumes associated with large diameter casings and demands special considerations while cementing.
