Isolation Valves

Barriers to contain fluids and prevent formation damage

Schlumberger isolation barrier valves safeguard reservoirs by providing a reliable barrier between the wellbore and formation and by containing fluids during completions and workover operations—preventing damage to the formation and minimizing workover costs.

Increased safety, efficiency, and production

• environments, including deepwater and subsea
• completion types: annular intelligent completions and those with stand-alone screens
• applications: ESP workovers, gravel- and frac-packing, temporary well suspensions, lubrication for long perforating intervals, and underbalanced perforating.

The FORTRESS isolation valve withstands severe debris environments and optimizes the available actuation energy—predictably, consistently, and reliably.
