The “MASTERFLOW” DrillCheck™ Valve is installed in the liner assembly to protect against fluid loss as well as act as a well barrier during subsequent activities.

An aluminum cage keeps a neutrally buoyant ball across the valve inlet. When the cage is broken during cement drill-out or by later intervention, the ball will check against the valve inlet.

The Valve Inlet acts like a conventional ICD during production.

• Allows for setting of open hole packers without inner string.
• Prevents fluid loss during drill-out of partially cemented (off-bottom cemented) liners.
• Acts as a conventional ICD during production.
