Customize Your Desired Casing System
System Type (Concentric, Eccentric, etc.)
We offer customization based on the fundamental design of the casing system itself, whether it’s a concentric system like Symmetrix, where drilling and casing advance simultaneously with the pilot bit inside the casing, or eccentric systems (like Odex) which have an off-center pilot bit. We can recommend and supply the most suitable system type based on the ground conditions, the need for bit retrievability, and overall project goals.
Casing Pipe Material and Thickness
The choice of casing material and wall thickness is vital for borehole integrity. We can customize casing pipes using various steel grades to meet specific strength and corrosion resistance requirements. Whether you need standard-duty casing for relatively stable ground or heavy-duty, thicker-walled casing for challenging, abrasive, or highly fractured formations, we ensure the material stands up to the job.
Casing Shoe Design
The casing shoe, located at the bottom of the casing string, is critical for effective penetration and sealing. We provide a range of customizable casing shoe designs, including those with carbide buttons for harder ground, or more robust cutting edges for challenging overburden. This customization ensures the system can efficiently cut through various strata and securely seat the casing.
Diameter and Length
We understand that every project has unique borehole dimensions. We offer a wide array of customizable casing diameters and lengths to perfectly match your drilling requirements. This includes both standard industry sizes and bespoke dimensions to accommodate specialized applications, ensuring seamless integration with your existing equipment and the desired depth of your boreholes.
what is a casing system?
A casing system is a specialized drilling method and set of tools used to stabilize boreholes, particularly in unstable ground like overburden, sand, or fractured rock.
It involves simultaneously drilling and installing steel casing pipes into the ground, preventing hole collapse and ensuring a secure pathway for further drilling or for the installation of foundations or piles.
what is casing system used for?
A casing system is primarily used in drilling operations to ensure the stability and integrity of a borehole, particularly when drilling through unstable or challenging ground conditions. Its main purpose is to prevent the collapse of the drilled hole, which can occur in loose soil, sand, gravel, fractured rock, or overburden.
Stabilizing Unstable Ground: Casing systems are essential for maintaining the open integrity of boreholes drilled through unconsolidated materials or highly fractured rock. By simultaneously drilling and installing a steel casing, the system provides immediate support to the borehole walls, preventing cave-ins and ensuring a clear path for further drilling or subsequent operations.
Protecting the Borehole: They serve to protect the borehole from contamination by groundwater or ingress of loose materials from the surrounding formation. This is particularly important in environmental drilling, water well construction, or any application where maintaining the purity of the borehole or preventing blockages is critical.
Facilitating Deeper Drilling: In cases where drilling needs to penetrate through multiple layers of unstable material to reach competent rock below, casing systems allow for the safe and efficient advancement of the drill string. Without casing, deeper drilling in such conditions would often be impossible due to continuous hole collapse.
Creating Permanent Structures: Beyond just drilling, casing systems are widely used in the construction of foundations for buildings, bridges, and other structures. The installed casing can serve as a permanent lining for piles (e.g., bored piles) or as a temporary support structure during the pouring of concrete.
Controlling Fluid Loss/Gain: In certain drilling scenarios, casing can help manage fluid loss into porous formations or prevent unwanted fluid influx into the borehole. This contributes to better control over drilling parameters and safer operations, particularly when dealing with varying hydrostatic pressures.
types of casing system
Casing systems are vital for stabilizing boreholes in challenging ground conditions and come in several distinct types, each designed for specific geological scenarios and drilling methodologies.
These casing systems allow for simultaneous drilling and casing installation, preventing hole collapse and ensuring a secure bore, especially in overburden, loose formations, or fractured rock.
Concentric Casing System: In this system, the drilling tools and casing advance simultaneously, with the drill bit and reaming mechanism positioned concentrically within the casing pipe. The most common example is the Symmetrix system, which often features a retrievable pilot bit. This design is highly effective in unstable ground as it provides continuous support to the borehole.
Eccentric Casing System: This type utilizes an eccentric, or off-center, reaming bit that rotates outside the casing to create an oversized hole, allowing the casing to follow. Once the casing is installed to the desired depth, the eccentric reaming bit can often be retrieved. The Odex system is a popular example, widely used for overburden drilling and anchoring applications.
Drill-Through Casing System: Unlike concentric or eccentric systems where the casing advances with the drill string, drill-through systems allow drilling to continue through the pre-installed casing. The casing is typically driven or vibrated into place first, then drilling proceeds inside it. This method is often used for deeper holes where multiple casing strings may be required, or where the initial casing serves as a guide for subsequent drilling.
