In applications where you need to run an API-qualified safety barrier above your electric submersible pump (ESP)—and want to maintain all the benefits of a totally rigless operation—the Torus™ insert safety valve is the answer to your dilemma. It’s the only insert safety valve that accommodates coiled tubing and doesn’t require a rig for installation. By using a sliding sleeve design to control flow instead of a flapper, the Torus valve maintains a permanent conduit for coiled tubing through the valve, enabling rigless ESP deployment with the protection of an API 14A-qualified barrier.

The REACH™ wireline-retrievable safety valve provides the industry’s first and only solution to bring ultra-deepwater wells with failed tubing-retrievable safety valves back online faster, safer, and more economically than a deepwater workover. FASTER Deepwater workovers can cost as much as $60M to recomplete the well and may take a year or more to begin depending on rig availability. The REACH WRSV only requires a light well intervention (LWI) vessel to perform the job at approximately one-quarter the cost of a workover. This not only avoids the high CAPEX of a major rig workover but can also expedite plans as LWI can typically be deployed in about half the time, bringing the well back on sooner and recovering additional production quicker. SAFER With traditional workovers, pulling the completion string requires considerable operations and logistics, as well as increased exposure to HSE risks. Utilizing a REACH WRSV eliminates problems that may arise with pulling and recompleting wells. In addition, the REACH WRSV reduces the number of personnel required on location, thus eliminating potential exposure to HSE risks. MORE ECONOMICAL The REACH WRSV is tubing pressure insensitive, allowing it to be operated by the same hydraulic control system that was originally used to operate the failed TRSV. This allows you to: • Remove the need to modify or change subsea equipment, eliminating further CAPEX • Eliminate the need to pull the entire upper completion to perform the operation, so the original completion is still intact and operable after the intervention work is complete • Avoid high CAPEX for equipment for a full recomplete and operating costs of a workover vessel • Have valve inventory on hand, ready to go at a moment’s notice so that the well can be brought back online faster than a complete workover • Take advantage of doing other LWI work at lower cost while the valve is deployed (i.e. chemical treatments) since the LWI vessel is already on location HOW IT WORKS The REACH WRSV is hydraulically controlled from the surface through the original control line that connects the inoperable TRSV to the surface emergency shutdown system. It is a normally closed valve, so that when the applied control chamber pressure is removed, the valve automatically returns to the closed position. Rather than utilizing a nitrogen charge, the Reach WRSV utilizes an atmospheric chamber, further enhancing reliability. Building on the same robust design principals as the existing REACH TRSV, the REACH WRSV is rated to 12,500 psi (861.8 bar) at 300°F (148.9°C) to ensure reliable performance in harsh, deepwater environments and it significantly exceeds API 14A Annex B V3 and V2 flow testing. Choose the only wireline-retrievable safety valve that can bring your wells back online faster, safer, and more economically than a deepwater workover. Call your local Baker Hughes representative to learn how the REACH wireline-retrievable safety valve can help you get your wells back online in one quarter of the cost and in half the time.

Reliably maintain your producing well’s surface pressure and flow rate with the A4™ wireline-retrievable velocity valve from Baker Hughes. The A4 valve is a subsurface-controlled subsurface safety valve engineered to help deliver optimal production at minimal risk. The valve is designed to be normally open but then automatically closes when the flow rate increases beyond the valve’s preset closing conditions. Control your production flows, safely and securely If loss of normal well control occurs at the surface and flow velocity increases, a pressure drop is created across an orifice. The resulting force generated by this pressure drop causes the valve’s flow tube to retract and the valve to close, effectively shutting in the well. The valve will reopen once pressures equalize across the flapper. The valve can be efficiently run and retrieved using conventional wireline methods, and readjusted onsite to meet changing well conditions. The A4 velocity valve includes a unique equalizing subassembly, which permits pressure from below the valve to equalize prior to valve retrieval. The valve is versatile and capable of setting at any depth. You can confidently run the A4 valve in tubing sizes ranging from 2.375 in. to 7 in. and with working pressures up to 10,000 psi.

The Baker Hughes CEMENTSAFE™ tubing retrievable surface controlled subsurface safety valve (TRSV) is custom-designed to prevent debris contamination in your cement-through and frac-through applications CEMENTSAFE valves are designed to deliver reliable operation and superior performance in any application that requires the exclusion of flowing debris from the working components of the TRSV. A piston with nonelastomeric dynamic seals isolates the control chamber and spring cavity from cement and produced fluids. This feature not only protects the sealing surfaces of your valve’s actuation system, but it also excludes debris from entering the valve’s flapper cavity. CEMENTSAFE ensures superior performance in harsh environments by incorporating many proven features from the T-series™ line, including: Metal-to-metal housing seals prevent wellbore fluid contamination and provide a strong seal A unique curved flapper optimizes the OD to ID relationship A patented thru-the-flapper self-equalizing system ensures pressure balance A patented radial punch control fluid contamination system eliminates accidental communication associated with linear shifting sleeves Discover how CEMENTSAFE series subsurface safety valve can help you prevent uncontrolled flow and debris contamination in your cement-through and frac-through operations.

Effectively control the volume of gas entering your well annulus with the VR™ annular vent valve from Baker Hughes. This proven solution minimizes free gas exposure to your electrical submersible pumping (ESP) systems—improving pump uptime while optimizing production flow. This annulus control safety valve attaches directly to the top of your twin-seal submersible pump packer to control gas flow across the packer. The VR gas vent valve can also be mounted in a vent port in the packer to reduce the volume of gas. Ensure reliable annular control with a simple, efficient design. The VR vent safety valve is normally closed, but is effectively opened by applying control line pressure. Any loss of control line pressure results in a fail-safe closure to stop annular flow. The valve’s optional recirculation feature allows circulation of fluid from the tubing to annulus. Upon loss of control line pressure, this feature allows pumped fluid to be re-circulated from tubing to annulus below the packer. Whether your applications call for venting for submersible pump completions or injecting for gas injection completions, the VR valve gives you safe, reliable annular control. Contact us to learn how the AGV ESP annular vent valve can safely control gas flow to protect your ESP systems.

Get assured annular flow control with the Model CASVTM annular control safety system from Baker Hughes. This surface-controlled, tubing-retrievable annulus safety valve delivers reliable performance when it matters most. Proven design features ensure that annular flow from the well is effectively closed off, precisely when it is required. The CASV annular control safety system is controlled from surface via a small diameter hydraulic control line connecting the safety valve to the surface emergency shut-down system. The valve’s fail-safe closed design ensures that when the applied control line pressure is removed, the valve automatically returns to the closed position—quickly shutting in annular flow from the well.
