Wire Scratcher

The COS Wire Scratcher is designed to remove mud cake and other debris from the casing surface, ensuring a cleaner wellbore and stronger cement bonding. Its rugged wire construction creates a consistent scratching and brushing action during casing reciprocation or rotation, helping improve mud displacement and cement adhesion in both cased and open holes.

Key Benefits

• Effective mud cake removal for improved cement-to-formation bonding
• Durable wire construction ensures long-lasting performance
• Enhances slurry displacement by creating turbulence around casing
• Suitable for vertical, deviated, and horizontal wells

Features

• Slip-on design for easy installation
• Made with high-strength tempered steel wire
• Available with hinged or solid band options
• Compatible with casing sizes 2 7/8” to 30” (custom sizes on request)

Applications

• Cleaning casing surfaces before cementing
• Improving slurry placement in irregular wellbores
• Use in primary cementing operations across varied well conditions
