Protect your reservoir

Isolate reservoir fluids within the lower completion using the FIV-II formation isolation valve. A bidirectional barrier, the valve enables operators to transition seamlessly—without intervention—from the lower to the upper completion.

  • Enhance well productivity by preventing formation damage and minimizing fluid loss
  • Save rig time and costs by reducing interventions
  • Increase safety by providing a downhole barrier against pressure reversals

Open the valve without intervention

The valve features the Trip Saver one-time remote-opening mechanism, which eliminates the need for an intervention to open the valve one time. Instead, cycles of tubing pressure are applied against the closed valve in a number predetermined by an integral indexing mechanism.

Use for fluid loss control, underbalanced perforating and multizone isolation

The valve has a wide range of applications, including fluid loss control, underbalanced perforating, well control barrier operations, and multizone isolation. Because of the rotating ball and floating seal design, the valve is more debris tolerant compared with previous designs, making it especially useful in sandface completions.

Rely on this barrier for well interventions and well suspension

The FIV-II valve is qualified and tested with gas to a zero-bubble leak rate across the ball sealing mechanism from below under specified conditions. This stringent acceptance criterion enables the valve to be used as a barrier for well intervention operations and for well suspension before the Trip Saver mechanism is activated.
