Well Miller® CVF
Continuous Variable Force
Well Miller® CVF – Continuous Variable Force – is a comprehensive and dynamic system engineered to fully optimize hardware milling operations.
Utilizing multiple parameters measured throughout the milling process in real-time (including direct measurements of weight on bit, and rate of penetration), the CVF system produces levels of control, precision, and accuracy inspired by our manufacturing expertise, blurring the lines between milling and downhole CNC machining.
Since late 2019, an IOC had faced a highly challenging situation offshore of Congo, where the necessary replacement of a subsea Christmas tree was being prevented by a gate valve that was stuck in ...
Born out of proven mechanical and clean-out services with an extensive track record, the Well Miller® CVF system is an integration of key features and benefits of several technologies, enhanced by multiple data measures for detailed Surface Readout (SRO) capability.
Up to 5,000 lbs of force is dynamically delivered to the mill bit in increments of 100 lbs under full surface control. The active CVF system provides fully optimized operations, minimizes required milling time, and provides flexibility to the entire milling operation in relation to changes in geometry, and material of the objective.
