Reamer Casing Shoe
Our reamer casing shoes are equipped with cutting elements that ream the wellbore as the casing is run in. This is particularly useful in tight holes or when navigating through formations with washouts, ensuring the casing can reach its full depth without getting stuck.
Coring Casing Shoe
We specialize in coring casing shoes, which are designed for applications where obtaining a continuous rock sample is critical. This specialized casing shoe allows for core retrieval while simultaneously advancing the casing, streamlining the drilling and sampling process for geological analysis.
Casing System Components
Ring Bit: This component initiates the drilling process, cutting an oversized hole to accommodate the casing. It ensures a smooth and precise start for the entire system, crucial for maintaining drilling accuracy.
Casing Shoe: Positioned at the bottom of the casing, the casing shoe protects the casing from damage during drilling and helps guide it into the drilled hole. Its robust design prevents premature wear and tear.
Retainer Ring: This ring securely holds the ring bit in place, preventing it from detaching during operation. It’s a critical safety feature, ensuring the integrity of the drilling assembly.
Casing: The primary structural component, the casing lines the drilled hole, preventing collapse and ingress of groundwater. It provides stability to the borehole, allowing for further operations to proceed safely.
Pilot Bit: This bit leads the drilling, creating a smaller pilot hole that the ring bit then enlarges. It’s essential for guiding the entire system and ensuring the correct trajectory of the borehole.

what is casing shoe?
A casing shoe is a specialized device attached to the bottom of the casing string in a drilling operation. It is a critical component that serves multiple functions to ensure the success and integrity of the wellbore.
Primarily, its bull-nosed or rounded design helps guide the casing string through the wellbore, protecting it from damage as it navigates past ledges, washouts, and other potential obstructions.
Beyond guidance and protection, the casing shoe is integral to the cementing process, as it provides a path for cement to be pumped out of the casing and into the annulus, creating a stable seal between the casing and the wellbore wall. Some types, like the float shoe, also contain a check valve to prevent cement from flowing back into the casing.
what is casing shoe made of?
A casing shoe is typically a composite tool made from a combination of hard and drillable materials. The outer body of the casing shoe, which connects to the casing string, is generally made of high-grade steel to provide structural integrity and durability. The inner parts, including the nose or core, are made from materials that are easy to drill through later in the well’s life.
This allows for deepening the well after the casing is set.
Steel: The outer shell and threaded connections are made of steel to withstand the downhole stresses, including weight, rotation, and abrasion, while running the casing into the well.
Drillable Materials: The inner components are made from materials that can be easily drilled out by a standard drill bit. These often include cement, aluminum, or thermoplastics to ensure that drilling can continue to the next depth.
Tungsten Carbide and Diamonds: For specialized applications, like in reamer casing shoes or coring shoes, the tool may incorporate harder, more abrasive-resistant materials. This can include tungsten carbide inserts or even diamond cutting elements to aid in drilling through challenging formations.
what is casing shoe used for？
A casing shoe is an essential piece of equipment in drilling operations, primarily used to protect and guide the casing string as it is lowered into a wellbore. This is crucial for maintaining the integrity of the hole, especially in unstable formations where the wellbore might otherwise collapse.
It’s often the first component to touch the bottom of a new section of the hole.
Protecting the Casing: The casing shoe acts as a shield for the casing string, preventing the bottom end of the pipe from being damaged or bent as it scrapes against the wellbore wall or encounters hard formations.
Guiding the String: Its rounded or tapered nose helps guide the casing past obstacles like ledges and washouts, ensuring it reaches its target depth without getting stuck.
Facilitating Cementing: The shoe provides an exit for drilling fluids and a passage for the cement slurry that is pumped down the casing to create a seal in the annulus (the space between the casing and the wellbore).
Preventing Backflow: Certain types of casing shoes, known as float shoes, contain a check valve that prevents the cement slurry from flowing back into the casing after it has been placed, maintaining a proper cement column.
how to install casing shoe?
Installing a casing shoe is a critical step in preparing a wellbore for casing. The process is straightforward, ensuring the shoe is securely attached and functional before the entire casing string is lowered into the hole.
Proper installation guarantees the shoe performs its protective and guiding functions effectively.
Step 1: Preparing the Casing Joint
First, we inspect the bottom joint of the casing string to ensure the threads are clean and free of damage. We then apply thread compound, a specialized grease that lubricates the threads and helps create a pressure-tight seal, preventing leaks during operation and cementing.
Step 2: Threading the Casing Shoe
Next, the casing shoe is carefully threaded onto the bottom of the prepared casing joint. It’s crucial to ensure a proper, hand-tight fit before using a casing power tong or specialized tool to tighten the connection to the specified torque value fully.
Step 3: Verifying the Connection
Once the casing shoe is tightened, the connection is visually inspected to ensure there are no gaps between the shoe and the casing joint. We then verify that the torque applied meets the manufacturer’s and project’s specifications, which confirms a secure and robust mechanical connection capable of withstanding downhole forces.
Step 4: Lowering the String
With the casing shoe securely installed, the entire casing string, joint by joint, is lowered into the wellbore. The casing shoe, now at the very bottom, protects the string from damage and guides it past any obstacles or tight spots on the way to the final setting depth.
