Product Description
Stab-in Casing Float Collar And Float Shoe API or As required The cement float collar& shoe offer dependable performance for all classes of oil and gas wells. The plunger type valves prevent cement backflow, provide casing buoyancy during run-in, and act as internal bops during the process of running and cementing the casing. Our float collar & shoe sizes range from 5 1/2” – 30” with float ball, stab in, non-rotating, spring and single / double valve types. Products in our factory are all manufactured to API standard, with strict quality control and inspection. Features of Float Collar and float Shoe: The Stab-in cementing technique is a highly efficient method employed in drilling operations to effectively cement larger diameter casings. By utilizing a smaller diameter inner string of drill pipe, it reduces displacement volume and minimizes contamination, resulting in time savings. To minimize the need for drill-out of cement within the large casing, the Stab-in Shoe incorporates a plunger valve and displacement fluid in the drill pipe. This allows for precise control over displacement and enhances the quality of the cement. With a reduced cement/mud interface area and high flow velocity within the drill pipe, contamination is minimized, and the short pumping time eliminates the requirement for cement retarders. One significant advantage of the Stab-in method is the reduction in cement volume. Unlike conventional displacement methods that involve complex calculations for excess cement, the Stab-in method simplifies the process by considering only the volume of the drill pipe as excess cement, eliminating the need for large plugs. The Stab-in technique significantly reduces rig time by improving displacement accuracy and minimizing the drill-out process. This leads to reduced circulating, pumping, and drill-out times, ultimately enhancing operational efficiency. Furthermore, the Stab-in method offers casing protection as the cementing pressures are confined to the drill pipe, similar to a squeeze job. This provides an additional safeguard to prevent excessive pressure on the casing. The Stab-in cementing equipment is available in a wide range of sizes, from 4-1/2" to 36". Additionally, the Stab-in cement Float Shoe & Collar can be customized with various combinations, including Double Valve, to meet specific requirements. Overall, the Stab-in cementing technique is a reliable and effective method for cementing larger diameter casings in drilling operations. Specification of Float Collar and float Shoe:
