Stab-in Casing Float Collar And Float Shoe API or As required
The Stab-In Float Collar and Shoe technique is a widely adopted and efficacious means for cementing large diameter casings. This method requires directly inserting the drill pipe into either the float shoe or collar, and subsequently pumping cement through the drill pipe until it reaches the surface. An essential step to guarantee adequate cement distribution involves utilizing a wiper dart to displace the cement to the bottom of the drill pipe.
Additionally, the drill pipe is circulated, retrieved, and removed from the wellbore. To effectively separate the cement from the mud and eliminate any cement within the casing, oversized plugs are indispensable during the cementing process. It is important to note that the stab-in float collar and shoe technique is specifically designed for cementing large diameter casings that are lowered using drill pipe. Due to the significant displacement volumes associated with this operation, special considerations must be taken into account.
- Small diameter inner string off drill pipe is used to displace cement which minimizes displacement volume behind Cement and there by reduces contamination and save time.
- Drill out of cement inside large casing is minimized by controlling cement top with displacement fluid in drill pipe And Plunger valve in Stab in Shoe
- Improve displacement accuracy — cement mixing and pumping continues until cement returns reach surface
- Get better cement quality — the reduced cement/mud interface area and high velocity of flow in the Drill
- Pipe Minimize cement contamination while the short pumping time eliminates the need for cement retarders
- Reduce cement volume — conventional displacement requires calculation of excess cement factor, whereas with Stab-in methods excess cement need be no greater than the volume of the drill pipe. No large plugs are needed
- Reduce net rig time — circulating, pumping, and drill-out times are minimized
- Protect casing — cementing pressures are confined to the drill pipe as in a squeeze job
- The Stab-in cementing equipment is available in size 4-1/2”-36”
- The Stab-in cement Float Shoe & Collar are also available with Double Valve and any combination.
