Large-bore window-exit system for 13-5/8″ casing — the platform delivered and accepted for North Africa workover programs, held to the same machining standard on every component.
Use case: sidetracks and re-entries in large casing programs where window geometry and mill stability decide the job. The standard our customer accepted on this platform is the standard we hold on every system — documented deliveries, full traceability, and repeat-order machining quality.
