Isolation & Barrier Valves

Unparalleled Barrier and Zonal Isolation

Whether it’s concentric string completions or otherwise, Superior Completion Services has established its reputation as an industry leader in well isolation systems. In fields around the world, our unique sealing mechanism and fluid loss devices deployed with the ISO system are proven staples. When paired with the Superior interventionless flow valve suite, it delivers unmatched flexibility to your completion program for standard, highly deviated and/or complex trajectories, and deepwater fields. For green or brown field development, it’s the obvious choice.

Interventionless Innovation

Dramatically reducing timeline and overall cost, Superior Completion flow valves apply innovative technology for fluid loss control at sandface and interventionless production. Our valves seamlessly integrate with ISO systems, which easily interface with upper completion valves, enabling production zone of choice by application of hydraulic pressure. By providing a contingency mechanical opening, they also reduce risk.

Production Flow Valves

  • Reclosable Pressure-Actuated Circulating Valve (X-PAC)
  • Reclosable Radial Flow Valve (X-RFV™)
  • Reclosable Annular Flow Valve (X-AFV™)
  • Pressure-Actuated Circulating Valve (PAC)
