Foam Wiper Ball for Efficient Oil and Gas Drilling Operations
Engineered for Precision, Durability, and Reliability in Demanding Environments

In high-performance oil and gas drilling applications, effective drill pipe displacement and internal wall contact are essential to maintaining operational integrity. Residual drilling fluids, cement slurries, and solid debris can obstruct fluid circulation, impair zonal isolation, and increase the risk of non-productive time (NPT). Merit Automotive delivers a high-precision solution: premium-grade foam wiper balls, purpose-built to improve displacement efficiency and mechanical wiping during cementing and circulation stages.

Key Performance Features

Superior Displacement Efficiency
Merit foam wiper balls are designed to maximize wall-contact area inside tubulars, ensuring consistent removal of residual fluids and solids throughout the internal diameter of the pipe string. This improves cement placement and wellbore displacement quality across variable bore profiles.

Extended Drill String Longevity
By mitigating the accumulation of drilling residues and minimizing wear-inducing particulates, our foam wiper balls enhance the lifespan of drill pipe and bottom hole assembly (BHA) components. Their use significantly reduces the risk of internal erosion and flow restriction.

Field-Friendly Deployment
Our wiper balls are constructed for straightforward deployment via cementing heads, diverters, or liner hanger systems, enabling fast transition between operational stages and minimizing intervention time.

Operational Consistency in Extreme Conditions

• Thermal Resilience: Performance assured from -40°F (-40°C) up to 300°F (149°C) for both surface and downhole environments.
• High-Pressure Endurance: Capable of withstanding high downhole pressures without deformation or failure.
• Chemical Compatibility: Resistant to aggressive chemical components in oil-based muds, synthetic-based fluids, and spacer systems.

Versatility & Mechanical Adaptability

• Parting Stretch: Exceptional elasticity with a stretch range of 380%–500%, allowing unrestricted movement through constrictive tool profiles such as mechanical set packers, float collars, or stage tools.
• Multistage Compatibility: Effective in multiple casing and tubing sizes, including applications with changing IDs, without compromising structural integrity or functionality.
• Material Composition:
  • Natural Rubber: For flexibility and dynamic compressibility.
  • Polyurethane or Polyethylene Foam: Used in specific applications requiring maximum abrasion resistance and hydrocarbon compatibility.
  • High-Density Closed-Cell Foam: Prevents fluid absorption and maintains structural properties under load.
