Weatherford Wins 4-Year Safety Valve Deal

08 October 2019

Weatherford International, one of the largest multinational oilfield service companies providing innovative solutions, technology, and services to the oil and gas industry, has announced its largest-ever contract for deep-set safety valves. Under terms of a deal with Petrobras, Weatherford will deliver 24 Optimax deep-set safety valves in the next four years.

Weatherford is now extending its reliability to the deep and ultra-deepwater market. The Optimax deep-set safety valve protects against devastating loss of well control by providing fail-safe closures at pressures up to 10,000 psi and are rated for setting depths as deep as 12,000 ft. The valves are monogrammed to API-14A's highest validation grade of V1.

An essential part of the completion string, the deep-set safety valve is controlled by a primary hydraulic control line. Application of control-line pressure keeps the valve in the open position. When pressure is bled off, the valve closes to protect property, personnel, and the environment. A secondary upward-facing piston, plus heavy-duty power springs, enable fail-safe closure while keeping the hold-open pressure to a minimum.
