Executive Summary

The 2 7/8" Surface-Controlled Subsurface Safety Valve (SCSSSV) is designed for use in wells with 2 7/8" tubing, a common standard size in the oil and gas industry. This valve serves as a critical safety device, automatically shutting in the well to prevent uncontrolled flow in the event of equipment failure or loss of surface control pressure.

It operates as a wireline-retrievable, flapper-type valve with a self-equalizing mechanism that helps maintain reliable function during shut-in and restart. Rated for pressures up to 10,000 psi, it is suitable for wells with moderate flow rates. The valve can be serviced or replaced without pulling the entire tubing string, which helps reduce well intervention time and operational costs.

Its compatibility with standard landing nipples and moderate size makes it a practical choice for many well types, including standard completions, workovers. The design balances safety, ease of maintenance, and operational reliability.

Detailed Description

Available sizes: 2 3/8”, 2 7/8”, 3 1/2”, 4”, 4 1/2”, 5”, 5 1/2'” and 7”.

The 2 7/8" Surface-Controlled Subsurface Safety Valve (SCSSSV) is designed to shut in a well to prevent uncontrolled flow caused by equipment failure or damage. It is installed in the upper wellbore to provide emergency closure of the production tubing, isolating the wellbore if there is a failure in the surface production control system or downhole equipment.

The valve operates on a fail-safe principle, closing automatically when control pressure is lost. It features a flapper-type mechanism and is surface-controlled through hydraulic pressure. The design is self-equalizing, which helps maintain pressure balance across the valve during shut-in and restart, ensuring consistent performance.

This valve is wireline retrievable, meaning it can be removed or serviced without pulling the entire tubing string, reducing well intervention time. It is compatible with landing nipples having seal bore diameters of 2.125", 2.188", or 2.313", allowing flexibility in well design.

The valve is rated for working pressures up to 5,000 psi and offers internal flow passage options of 0.81" or 1.12". The sealing surfaces are located outside the flow path when the valve is open, minimizing erosion and wear. The flapper is made from solid bar stock to provide mechanical strength and durability.

This configuration is commonly applied in wells where emergency shut-in is necessary and regular maintenance without tubing retrieval is preferred.
