Application Purposes
The 152017 model is designed for reliable wiping, fluid displacement, and separation within 7-inch tubulars and smaller internal diameters. It supports consistent and efficient push-down through vertical and horizontal sections, ensuring thorough interface control between fluids during critical wellbore operations.
Functional Features
✔️ Dimensional Recovery
Compresses through narrow restrictions (down to 1.000 in) and restores to full diameter with minimal fatigue.
✔️ Uniform Wall Contact
Expands to maintain pipe wall contact for uninterrupted wiping and flow assurance.
✔️ Superior Push Capacity
Maintains structure under differential pressure and turbulent flow conditions, driving residual fluids and materials forward.
✔️ Skin Durability
Resists tearing and abrasion, extending usable life in aggressive wellbore environments.
✔️ No Residue Left Behind
Performs without leaving behind foam fragments or degrading under high-pump-rate conditions.
Typical Operational Scenarios
- Spacer-wiper interface in cementing strings
- Pre-wipe and post-wipe ball in drill pipe sweeps
- Horizontal well wiping during displacement cycles
- Liner preparation and inner pipe integrity assurance
Conclusion
P/N 152017 – the 7″ Foam Wiper Ball – is optimized for tubular wiping and displacement performance in complex drilling and cementing sequences. Engineered for mechanical reliability, fluid transition efficiency, and resistance to deformation, it remains a trusted solution for operational reliability in the energy sector.
