Injection Safety Valves

Overview Library

Surface and subsurface control options

To maintain reservoir pressure for hydrocarbon production, many operators use water or gas injection as a secondary recovery technique. Safety and injection valve systems are installed to provide well control.

Conventional and deepset safety valves are normally used to provide surface control capability. Unlike surface-controlled safety valves, subsurface-controlled injection valves require no hydraulic control line to operate; they open under injection flow at predetermined injection flow rates and can be set at unlimited depths. They are available in tubing- or wireline-retrievable form, for production tubing sizes ranging from 2 3/8 in to 7 in and working pressures from 5,000 psi to 10,000 psi.

Tubing- vs. wireline-retrievable valves

Tubing-retrievable valves provide a fullbore ID (equivalent to the production tubing), enabling high-volume flow and reduced flow velocity. Wireline-retrievable valves can also be used for injection. However, they are installed in landing nipples or hydraulic communication nipples, and the reduced ID limits the flow capability and increases flow velocity.

TRC-II Tubing-Retrievable Charged Safety Valve

Deepset and ultradeepset, surface-controlled subsurface valves for working pressures up to 20,000 psi.

TRMAXX Premium Tubing-Retrievable, Surface-Controlled Safety Valve

Premium rod piston flapper valve for working pressures up to 10,000 psi, with an optional flapper-mounted equalizing system.

TRM-4 Tubing-Retrievable, Surface-Controlled Safety Valve

Premium rod piston flapper valve for working pressures up to 10,000 psi, with an optional side-mounted equalizing system.

Integrity Injection Safety Valve

Subsurface-controlled valve for working pressures up to 10,000 psi, engineered to prevent wells from flowing back or blowing out in the event surface controls malfunction or become damaged.

SlimTech Reduced-OD, Tubing-Retrievable, Surface-Controlled Safety Valve

Subsurface safety valves for conventional, high-rate gas, and deepset installations.
