Product Description

 

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

 

The stab-in float collar and shoe technique is an improved method used for cementing large diameter casing in drilling operations. This technique involves directly stabbing the drill pipe into either the float shoe or collar, allowing cement to be pumped through the drill pipe until it reaches the surface. To ensure proper cement placement, a wiper dart can be utilized to displace the cement to the bottom of the drill pipe. Once this is done, the drill pipe is lifted, circulated to ensure proper cement distribution, and then extracted from the hole.

 

It is important to note that when using stab-in float collar and shoe, large plugs are required to separate the cement from the mud. These plugs need to be drilled out along with any cement present in the casing. This technique is specifically designed for cementing large diameter casings that are lowered on drill pipes. Due to the high displacement volume associated with these large casings, special considerations must be taken into account during the cementing process.

 
Features of Float Collar and float Shoe:
 
  • 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.
