Controlled Upward Section Milling
Advanced stabilization, reduced torque, and configurable protection for multi-string casing integrity.
The SCORPION section mill is engineered for efficient upward section milling in both single- and multi-string environments, extending operational capability across smaller casing diameters and complex well conditions. Its patented Sweep Expansion Limiter (SEL) protects outer casing while reducing milling torque, and its hydraulically optimized, dual-piston design supports a wide range of flow rates for consistent downhole performance.
Supported by configurable blade sweeps, flow-through jetting for effective cuttings evacuation, and proprietary Reaper tungsten carbide inserts, the Scorpion delivers precise material removal and dependable section-milling execution on pipe or coiled tubing—expanding next-generation abandonment solutions across 4-inch to 9-5/8-inch casing applications.
