Functional Purpose
The 8″ foam wiper ball is designed to:
- Provide full circumferential wiping contact during pipe displacement.
- Promote effective fluid separation in downhole tubulars.
- Facilitate uniform transition between displacement fluids such as mud and cement slurries.
- Withstand long-distance pump-down operations and variable pipe geometries.
It is used primarily in cementing and displacement sequences where mechanical wiping of internal surfaces is essential for operation integrity.
Performance Characteristics
✅ Compression & Recovery: Capable of compressing through restrictions as small as 1.375 inches and regaining full shape for continued wiping.
✅ Full-Bore Contact: Maintains radial expansion and pipe wall contact during axial movement.
✅ Wiping Consistency: Uniform density and skin coverage provide repeatable wiping in every application.
✅ Flow Resistance: Designed to travel steadily in turbulent and laminar fluid environments without fragmentation.
✅ Debris Push Efficiency: High frontal surface tension displaces accumulated residues effectively.
Operational Uses
- Tubular wiping before and after slurry displacement
- Wiper ball launch in plug-and-dart or continuous flow cementing
- Pre-wipe and post-wipe during liner operations
- Drill pipe sweep and displacement fluid transition in horizontal or vertical wells
Conclusion
The 101319281 8″ Foam Wiper Ball is a robust, field-proven solution for critical tubular wiping operations. With excellent shape recovery, high compression resilience, and reliable fluid displacement performance, it is the professional’s choice in demanding environments across upstream energy operations.
