• 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.
