Weatherford International has announced that its new model WUDP-10 deep-set safety valve has been certified to V1 standards under the American Petroleum Institute (API) Specification 14A.
The valve is designed for deepwater applications and is effective at depths in excess of 12,000 ft (3,658 m). Additionally, because it operates independent of tubing pressure, the valve can also be set in shallow applications.
The tubing-retrievable valve uses conventional hydraulic functionality to provide long-term, reliable operation that is independent of nitrogen storage. Its design minimizes leak paths and incorporates a heavy power spring for fail-safe closure.
