Monox™ EXPANDABLE CASING TECHNOLOGY
The MonoX™ Expandable casing is an advanced open-hole liner technology designed to isolate trouble zones and mitigate the telescoping effect of conventional well designs. This technology optimizes completion size and extends drilling capabilities in formations with narrow pore-pressure or fracture-gradients.
Global Application & Performance
MonoX™ systems in 8", 11.75", and 15.75" diameters have pioneered global industrial applications in onshore China and offshore Middle East.
- Economic Impact: Proven to save up to $3 million per case in Middle Eastern offshore operations.
- Wellbore Integrity: Swiftly seals complex formations without reducing the usable wellbore diameter.
- Stability: Effectively reduces wellbore instability events and simplifies well architecture.
