Baker Hughes’s portfolio of subsurface safety valves deliver reliable performance when it matters the most, providing emergency closure in the event that well control is lost. We offer a full range of valves to suit applications ranging from shallow- to deep-set, and the valves are available in surface- and subsurface-controlled, tubing-retrievable, and wireline-retrievable options. All Baker Hughes valves undergo stringent prototype testing and conform to standards and specifications such as API and ISO, as well as requirements requested for your unique situation.

Our DeepShield™ deepwater subsurface safety valvesdeliver fail-safe performance in completions that require low operating pressures due to control system limitations. The patented DeepShield operating system provides simple and reliable operation in the most critical applications, and delivers the redundancy and assurance required in remote subsea wells. Innovative design and simple operation protect your investment.

The DeepShield valve is the industry’s first V1-validated subsurface safety valve as defined in API SPEC 14A Specification for Subsurface Safety Valve Equipment, Twelfth Edition. Per this specification, subsurface safety valves must now undergo more stringent prototype testing than was previously required. With only minor modifications, the Baker Hughes subsurface safety valve prototype test program was able to accommodate the new V1-validation specifications, and continues to exceed the requirements set forth by API.

Balancing the hydrostatic pressures ensures low operating pressures, even in deepwater applications. The dynamic seal configuration used for the operating piston represents a significant engineering achievement that uses reliable, field-proven sealing technology designed for nitrogen-charged safety valves. The valve features a patented operating system capable of closing in all applications, even if primary nitrogen chamber pressure is lost.

Baker Hughes has commercialized its Reconnect technology, the company announced at a news conference on 20 September at the SPE Annual Technical Conference and Exhibition in Florence, Italy. The system was developed by BJ Servicesas a technology to restore surface control to subsurface safety valves.

The system provides an alternative for re-establishing surface hydraulic control to surface-controlled subsurface safety valves (SCSSVs) that are inoperable due to compromised control lines or if the installation of a storm choke is undesirable, Mark Embrey, senior sales rep for Baker Hughes capillary services, explained at the news conference.

This technology is also a viable option for wells that were not completed with SCSSVs. It includes a wireline-retrievable safety valve, a through-tubing replacement control line that strings into the new valve assembly and a wellhead adapter. Installation requires a minimal crew and equipment suitable for almost any platform or wellsite, according to Baker Hughes.

SCSSVs are designed to stop flow in the event of a catastrophic failure. They are installed in the production tubing and are mandatory in most offshore wells and some land wells. Primary SCSSVs are held open by hydraulic pressure from a control line that runs through the annulus to the surface. If pressure in the control line is lost, such as during an emergency shutdown or if the line is cut, the valve will close and revert to its fail-safe closed position, stopping flow from the well.

Traditionally, a storm choke would be installed or a workover intervention would be performed to regain surface control. But the Reconnect system does not require a workover rig. Mr Embrey adds that the new system can be customized “to fit almost any wellhead and safety valve out there.”

In one GOM installation, a mature well developed a leak in the control line of its subsurface safety valve. Injecting sealants did not repair the leak. The operator considered installing a velocity valve, but the well was scheduled for a plug-and-abandonment operation for one zone and the perforation of a new zone. Adjusting and re-adjusting a velocity valve for the new zone was expected to be time-consuming and expensive because of the well’s remote location.

The operator installed the Reconnect system, which provided flexibility to vary the well’s production rate without the intervention required to pull the velocity valve and adjust the differential pressure settings. In addition, the operator could perform mandatory testing of the downhole safety valve without the added cost of a lift boat previously required due to the small platform’s limited crane capacity and deck space.

Peak has been instrumental in successfully fishing a parted tubing retrievable safety valve lockout tool for a major Oil Company in a Southern North Sea well. The Downhole Safety Valve (DHSV) is a vital component on the completion that will isolate the surface from wellbore fluids in the event of an emergency.

A fishing package including a high strength high temperature magnet and retrievable overshot performed a text-book recovery of the safety valve lockout tool which had parted downhole in the safety valve at 534 ft well depth.

Video footage established that the ‘bean can’ mechanism (part of the safety valve lockout tool which keeps the flapper permanently in open position) had successfully locked out the Downhole Safety Valve (DHSV). The sub-assembly housing on the bean can had fallen and was expected to be sitting in the 3.688” nipple at 8155ft.

Intermediate spool inserted below the Chrtistmas tree; spool provides a profile for landing the control line hanger and hydraulic penetration to allow control on WCS Safety Valve

Weatherford’s Brian Marr, Scott Carline and Scott Deyoung discuss how the Renaissance WDCL system enabled the retrofitting of a new control line inside existing tubing to reestablish connection with a surface-controlled subsurface safety valve (SCSSV). The installation, which was performed without a workover rig, improved production at a significant cost savings.

The well, an offshore oil producer in the Middle East, was required by law to include a SCSSV. Like all downhole safety valves, SCSSVs act as a failsafe to prevent the uncontrolled release of reservoir fluids in the event that surface wellhead integrity is lost. These valves are popular well control options in the industry due to their ease of operation, which consists of hydraulic control from the surface. Hydraulic pressure is applied down a control line connecting the valve to surface. During normal well operation, the continuous application of this hydraulic pressure keeps the valve open. When hydraulic pressure is removed during a wellhead integrity event, the valve is forced shut, thus acting as a failsafe to isolate the wellbore.

However, SCSSVs are prone to malfunction, which is commonly caused by piston failures, leaks within the valve body or some type of control line failure such as crushing, leaking or blocking by an obstruction. Such a control line failure occurred in the offshore Middle East well, which forced the valve closed and shut in production.

The conventional remediation method calls for bringing in a workover rig to pull the tubing, replace the blocked control line and then redeploy downhole. While this option is relatively cost-effective and easy to implement in an onshore well, the logistics, cost and complexity of performing a workover offshore make this a time-consuming and expensive operation. Even a relatively simple workover of an offshore well in the Middle East might cost upwards of US$6 million, according to estimates from the operator. Weatherford collaborated with the operator to develop an alternative process— an intervention that would restore functionality to the SCSSV by retrofitting a new control line and inserting a new valve within the existing well architecture. The operator required the intervention to be performed without killing the well, pulling the tubing or incurring the time delays and costs that commonly come with a major workover.

Upon review of the well parameters and intervention requirements, the operator decided to deploy Weatherford’s Renaissance WDCL system, a wirelineretreivable subsurface safety valve that allows both the control line and the safety valve to be replaced in a straightforward retrofit procedure. The system has a modified packing mandrel and wet connection, and a valve-and-lock assembly that can be installed in an existing tubing-mounted safety valve or safety-valve landing nipple. A capillary line is then run from the surface inside the tubing and connected to the valve to provide control. The retrofit process for this offshore well was performed from a jackup rig, and began by modifying the wellhead to provide the correct profile for the capillary hanger and gain access for the new capillary control line. A wireline crew set plugs in the well to keep the well isolated, after which the tree was pulled and a spool piece containing a hanger profile was installed. The tree was then reinstalled and after the wellhead was pressure tested, the wireline crew went back in and pulled the plugs.

Another trip downhole was conducted to lock open the existing tubing-retrievable safety valve, after which a new subsurface safety valve was deployed and landed inside the previous valve. Once the new valve was set, the capillary control line was run down the center of the tubing to a pod on the valve.

A weighted and centralized stinger placed at the end of the capillary string was used to join the capillary to a mating connection on the valve. This was a wet-connect assembly, which was hydraulically locked in place by applying pressure to the capillary string. The wet connect contains unique design features, including the ability to be mated and unmated should the capillary need to be removed, and dual-back check valves that prevent backflow through the capillary line as an additional safety feature.

The top end of the capillary was then landed into the new spool piece below the tree through a specially designed, 4-in. control-line hanger. A Type-H profile was provided above the hanger to allow for the installation of a backpressure valve, which would be required to secure the well during future wellhead maintenance.

The Renaissance WDCL was installed without incident, allowing the operator to bring the well back to full production quickly, while adhering to offshore safety regulations in the region.

A new spool piece was placed below the lower master valve on the wellhead. The spool piece was custom-built with a profile to lock the control line hanger in place, and polished bores for the seals.

The SPIN® is a patented concept that prevents inorganic scale from growing in pipes and valves. The principle can be applied in valves and other areas where a clean surface is necessary. The SPIN®s ability to prevent scaling in DHSVs is field proven in a well in Norway, and it has reduced the need for frequent operation of the valve as well as scale cleaning operations.

In 2018, SPIN® was successfully installed inside a tubing retrievable downhole safety valve in Norway where it reduced the valve cycling frequency by more than 75%.

Halliburton provides proven, high-performance tubing-retrievable and wireline-retrievable subsurface safety valves (SSSV) designed to reliably shut-in (fail safe) if a catastrophic event occurs, allowing operators to maintain safe operations.

Whether downhole or subsea, safety can be hard to achieve in the oil and gas industry. Sudden pressure spikes can ruin equipment, leading to production stoppages and worse. Protection starts at the component level, which is where Lee Pressure Relief Valvescome into play.

Our relief valves come in three main varieties. Safety relief valves are designed to be exercised for intermittent “pop-off” applications. Pressure-regulating valves are intended to operate more continuously with stable performance throughout the operating range. Thermal relief valves relieve a few droplets of fluid from a trapped volume expanding due to rising temperatures. Each type of valve plays an essential role in downhole oil tool applications, and each is manufactured to the exacting tolerances that this role requires.

Like all products from The Lee Company, pressure relief valves are small, lightweight, and incredibly durable– enough to serve out the entire lifespan of an oil tool. In addition, these products are available in a range of sizes and cracking pressures.

The Model IC valve provides safety for a variety of pressure relief applications including but not limited to: mud, slurry, and fracing fluid relief. The valve relieves pressure to prevent pump, hose and system damage on mud and slurry pump systems – ideal for pulsating pressure. Use instead of nitrogen-assisted valves or ball & spring reset valves where you need greater accuracy and reliability. Our hydraulic fracturing and mud and slurry relief valve ranges are exceedingly popular in the Oil & Gas industry.
