  • Working Pressure up to 20,000 Psi (138 MPa)
  • Temperature up to 450° F (232° C)
  • Dual completion
  • Elastomeric sealing
  • Full metal-to-metal seal completion for severe and harsh environment
  • ESP well completion
Compact Wellhead

Our Compact Wellhead System is designed to provide multi-stage wellhead solutions that can accommodate a wide range of casing programs, working pressures, and customer-specific drilling and completions requirements.

We offer compact wellheads that cater to:

  • Working Pressures of up to 15,000 Psi (103,5 MPa)
  • Fluid and gas-tight sealings
  • Complete range of material class, temperature rating, and PSL requirements of API 6A
  • Premium elastomer materials that are capable to withstand Rapid Gas Decompression (RGD) as per NORSOK M-710
  • Running and retrieval tools designed to meet API 6A Annex L requirement
  • Emergency equipment that includes a full range of slip-type hangers and packoff assemblies

CHRISTMAS TREES

Allow us to manage a complete configuration of Christmas trees ranging from Gate ValveHydraulic Actuator Gate Valve, Stack Valve Xmas Tree and Block Valve Xmas Tree for both onshore and offshore platform. At OMS, our Xmas Trees are reliable, field-proven, low maintenance and easy to use for field services.

Gate Valve

OMS Gate Valves are designed and manufactured to meet the demanding high-pressure-high-temperature (HPHT) requirement of upstream drilling and production.

We offer gate valves that cater to:

  • Various sizes from 1-13/16” to 9” bore
  • Working pressures of up to 15,000 Psi (103,5 MPa)
  • All API 6A material classes, temperature ratings and product specification level (PSL) 1 through 4
  • Individual stacked valves or solid block tree arrangements
  • Fully compatible OMS-HA hydraulic actuators
  • Fire safe designs that meet API Spec 6FA and 6FC
  • Performances that exceed API 6A PR Appendix F test and OMS 360-cycles endurance test

MUDLINE SUSPENSION SYSTEM

OMS offers Mudline Suspension System that is suitable for drilling, production, temporary abandonment, and reconnecting to the well. Our system effectively transfers the weight of the well to the seabed and provides a beneficial disconnect-and-reconnect capability.
