Welltec® Flow Valve - for inflow & injection management
The Welltec Flow Valve is a full bore valve that can be used for both production and injection purposes within the lower completion, the rugged design enables rotation during liner deployment.
With specially designed inlets and sealing system, the WFV is qualified to open and close multiple times under differential pressure whilst maintaining flow, from both injection and production scenarios.
The full bore design makes it ideal for intervention-enabled completions and together with Welltec Annular Barrier providing high pressure zonal isolation, the WFV forms an integral part of the Flex-Well® completion.
Featured case
An operator in West Africa expanded the objectives of their first well in a new field from producing first gas to producing first gas and first oil. This change in goals...
Flow valves enabling isolation of water /gas breakthrough:
• Full bore design provides smooth flow area to minimize delta P loss
• Coatings to minimize scale deposition
• Robust seal design for manipulation under delta P
• High burst, collapse and torque capability
• All variants can be combined with sand screens
Deployment and operation:
• Shifting by Well Stroker actuation or drive by solution
• SRO confirmation of sleeve position
• Standard shifting profile
• Liner can be worked and rotated during deployment
Available sizes and specifications:
• From 2 7/8” WFV to 9 5/8” WFV*
• High temperature WFV available
• Materials fit to meet client specifications for pressure and tensile
• Product datasheet will be deliver for selected WFV
• Other sizes available upon request (lead times and feasibility to be determined)
