Stab-in Casing Float Collar And Float Shoe API or As required
The stab-in float collar and shoe technique is an advanced method used in drilling operations to effectively cement large diameter casings. This technique involves directly inserting 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 accurate placement, a wiper dart can be utilized to push the cement to the bottom of the drill pipe. Afterward, the drill pipe is lifted, circulated to ensure proper cement distribution, and then removed from the wellbore.
It is important to highlight that when using the stab-in float collar and shoe method, significant plugs are required to separate the cement from the drilling mud. These plugs, along with any cement present in the casing, need to be drilled out. This technique is specifically designed for cementing large diameter casings that are installed using drill pipes. Given the substantial displacement volume associated with these larger casings, special considerations must be taken into account throughout the cementing process.
The Stab-in cementing technique is a highly efficient method used in drilling operations that effectively reduces displacement volume and contamination. By employing a smaller diameter inner string of drill pipe, it displaces cement with precision, resulting in significant 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 combination ensures accurate control over displacement and enhances the quality of the cement. The reduced cement/mud interface area and the high flow velocity within the drill pipe help minimize contamination, while the short pumping time eliminates the requirement for cement retarders.
One of the primary advantages of the Stab-in method is its ability to reduce cement volume. Unlike traditional displacement methods that involve complex calculations for excess cement, the Stab-in method simplifies the process by only considering the volume of the drill pipe as excess cement, eliminating the need for large plugs.
The Stab-in method greatly reduces rig time by improving displacement accuracy and minimizing the need for drill-out. This leads to reduced circulating, pumping, and drill-out times, ultimately enhancing operational efficiency.
Casing protection is another notable benefit of the Stab-in method. The cementing pressures are confined to the drill pipe, similar to a squeeze job, providing an additional layer of protection for the casing.
The Stab-in cementing equipment is available in various sizes, ranging from 4-1/2" to 36". Additionally, the Stab-in cement Float Shoe & Collar can be customized with different combinations, including Double Valve, to accommodate specific requirements.
