SUBSURFACE SAFETY VALVE (SSSV)

The tubing-retrievable subsurface safety valve (SSSV) provides well protection against pressure drop and system failure in wireline and thru-tubing operations. This retrievable safety valve is controlled from the surface with a hydraulic control line. The valve connects to the tubing string and remains open if adequate pressure is maintained. If pressure drops below the threshold (as occurs in the beginning stages of losing well control), the valve closes. This creates a barrier in the tubing to prevent fluids from rushing up the tubing.

The tubing-retrievable SSSV uses a fail-safe design to prevent the release of unwanted fluids during well completion. This is a critical HSE and well-control requirement on all wells capable of natural flow.

BENEFITS

Prevent uncontrolled release of reservoir fluids

—
Isolates the wellbore during a system failure or loss of pressure

Protect your people and the environment

—
Enables precise safety valve location with multiple pressure ratings and setting depth options

applications

Well completions
Operations requiring tubing-mounted, wireline-retrievable, and thru-tubing options

capabilities

Retrievable with wireline and slickline
Non-equalizing or self-equalizing flapper options
Pressure ratings of 5,000 psi
(352 kg/cm) and 10,000 psi
(703 kg/cm) – custom ratings available
Multiple setting depth options from shallow to deep
Adjustable upper and bottom thread

features

Reliability is improved with the metal-to-metal seal used in the sealing chamber
If a tubing-retrievable valve fails, a wireline-retrievable valve may be used inside the production tubing to avoid a workover
