ProMILL® Milling and Underreaming System
Efficient Wellbore Access for Complex Intervention Operations
The ProMILL® milling and underreaming system is engineered to improve wellbore access by combining efficient milling and underreaming capabilities in a single, versatile platform. Designed for intervention, remediation, and abandonment applications, the system helps operators remove casing, enlarge wellbore diameters, and prepare the foundation for an abandonment cement barrier in a single run with greater efficiency and control.
Benefits
Reliable Performance Across Multiple Applications
From setting a bridge plug and casing section milling to wellbore enlargement and access restoration, the ProMILL® system provides a versatile solution for a broad range of intervention requirements. The system’s robust design and field- proven engineering help operators execute critical operations with confidence while maintaining efficiency in demanding well conditions.
Eradicate All Leak Paths with a Rock-to-Rock Barrier
Complex wells require dependable tools that adapt to changing downhole conditions. The ProMILL underreaming system is engineered with TruEdge™ milling elements for enhanced durability, stabilization, and consistent performance throughout the operation. Featuring ball-drop activation and a high-ratio underreamer, it enlarges wellbore diameter and prepares the foundation for an abandonment cement barrier in a single trip. By eliminating all leak paths and achieving rock-to-rock zonal isolation, the ProMILL system helps operators reduce operational uncertainty and deliver successful intervention, remediation, and abandonment outcomes.
