Isolation Valves

Barriers to contain fluids and prevent formation damage

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

Increased safety, efficiency, and production

Isolation valves will help you increase wellbore safety by isolating the formation and containing reservoir fluids, increase efficiency by enabling batch drilling and completion operations, and enhance production by preventing formation damage.

Proven reliability

Schlumberger installed the industry’s first barrier valve in 1996. Since that time, we have installed more isolation valves than all other manufacturers combined―more than 2,300. Today, all our isolation valves use core technology components from the original FIV formation isolation valve, resulting in the most tested and reliable isolation barrier valves available.

Wide range of applications

We offer isolation valves to suit a range of

  • environments, including deepwater and subsea
  • completion types: single- or mutiple-zone completions; intelligent completions
  • applications: fluid loss control, gravel and frac packing, well suspensions, ESP workovers, underbalanced perforating, and downhole lubricator valve.
