Mechanical Stage Cementing Tool
The COS Mechanical Stage Cementing Tool enables casing strings to be cemented in two stages, reducing overall pumping pressure and improving cement placement in long casing runs. Known for its simplicity, reliability, and low-risk performance, this tool is the preferred choice in wells where proven technology is essential.
Key Benefits
- Ensures safer, more efficient multi-stage cementing
- Reduces total pumping pressure in long casing strings
- Prevents lost circulation in weak or fractured formations
- Minimizes rig time with simple, compact design
- Reliable performance with minimal moving parts
Features
- Two-stage cementing capability for improved zonal isolation
- Compact, simple construction → easy to handle and install
- Internal sleeve system prevents premature opening under formation restrictions
- Clear surface indications for precise opening and closing
- Rugged design engineered for durability in demanding well conditions
- Available sizes: 4 ½” to 13 3/8” (custom sizes available on request)
Applications
- Long casing strings requiring staged cementing
- Wells with weak formations where full-column cementing may cause problems
- Vertical, deviated, and horizontal wells needing pressure reduction and safer cement placement
