New Milled Reamer Shoe casing
A Reamer Shoe can effectively handle expected or sudden problems during the running-in of casing and liners, providing reliable protection.
It is specially designed for complex wellbore conditions and can deal with situations such as swelling shale, ledges, and wellbore washouts.
Various API standard and special thread connections are available upon request, with sizes ranging from 4-1/2 inches to 20 inches.
How does a reamer shoe working?
A reamer shoe is designed with cutting structures or blades on its outer surface, which are typically made of tungsten carbide or other hard, durable materials. As the casing string is lowered, these blades rotate with the casing and ream out any tight spots, cuttings beds, or bridges that could prevent the casing from going all the way to the bottom.
This differs from a standard guide shoe, which simply helps the casing slide past obstructions. The reamer shoe actively “drills” or “reams” through them, ensuring a clean and unobstructed path.
advantages of a reamer shoe
Overcoming Obstructions: Its primary advantage is its ability to handle difficult wellbore conditions. In deviated or horizontal wells, or in formations that are prone to sloughing (collapsing), a reamer shoe is often the only way to get the casing to the bottom of the well.
Time-Saving: It eliminates the need for a separate trip to run a reaming bit, which saves significant rig time and costs.
Improved Cementing: By ensuring the casing is fully on the bottom and the hole is clean, it facilitates a more effective cementing job. A well-placed casing string is essential for a proper cement seal around the outside of the pipe.
Ream Shoe: Traditional Welted V.S. new Type Milled
| New Milled Reamer Shoe (CNC) | Old Welded Reamer Shoe | |
|---|---|---|
| Manufacturing Process | One-piece milling from a single block of steel. | Multiple pieces welded together. |
| Structural Integrity | Superior. No stress points or brittle areas from welding. | Lower. Welding can create weak spots and residual stress in the metal. |
| Performance | Highly precise cutting geometry. | Less precise, depends on welding quality. |
| Reliability | Extremely high. One-piece design reduces the risk of failure. | Lower. Welded joints can fail under high stress. |
| Overall Value | Exceptional. Same price for a technically superior, more reliable product. | Good, but limited. The value is capped by the limitations of the manufacturing process. |
Why the New type milled reamer shoe is Better than the traditional welded?
- Seamless, uniform body eliminates weak points. Retains the original strength and integrity of the steel.
- Higher durability to withstand extreme downhole pressure and torque without fracturing.
- More aggressive and consistent reaming. Efficiently clears obstructions and cleans the wellbore.
- Reduces operational risk and costly downtime caused by tool failure.
- Higher ROI for your operation. You get a premium tool without the premium price tag.
