Product Description
Stab-in Casing Float Collar and Float Shoe
Stab-in float collar and shoe systems provide an advanced cementing solution for large diameter casing applications. This method involves stabbing drill pipe directly into the float shoe or collar and pumping cement through the drill pipe until returns reach the surface.
Key Features and Benefits
- Small diameter inner drill pipe minimizes displacement volume, reducing contamination and saving time
- Minimized drill-out requirements by controlling cement top with displacement fluid and plunger valve
- Enhanced displacement accuracy with continuous cement mixing until returns reach surface
- Superior cement quality through reduced cement/mud interface and high flow velocity
- Reduced cement volume requirements compared to conventional displacement methods
- Optimized rig time through minimized circulating, pumping, and drill-out operations
- Casing protection with cementing pressures confined to drill pipe
- Available in sizes from 4-1/2" to 36" with double valve options
