Eccentric Under-Reamer

ECR | Eccentric Under-Reamer

Under-reaming is used to allow a wider clearance for running and cementing casing correctly as a result of poor wellbore quality. Active under-reamers are typically employed. ECR fulfils this requirement for limited enlargement needs without the complexity and cost of active tools.

• Redundant and independent locking mechanisms providing unmatched downhole safety
• A unique two-way lubrication and pressure compensation system design
• Optimized bearing load distribution and bearing treatment for improved bearing life
• An optimized cutting structure for maximum reaming efficiency
