Storm Choke® H safety valves are ambient-type, wireline retrievable valves that are normally closed and precharged with a set dome pressure. When the well flowing pressure drops below the predetermined dome-pressure charge, as a result of a rupture in the flowline or surface equipment, the dome pressure and valve spring are designed to close the valve, shutting in the well. The H valve is used in wells producing large volumes of abrasive fluids. Its large bore is not restricted by a flow bean. The valve is designed to resist pressure surges. A metal-to-metal (MTM) ball and seat is used as the primary closure mechanism. The H valve is ideal for protecting wells with declining bottomhole pressure because this valve is tubing pressure sensitive instead of velocity sensitive. To reopen, the valve pressure must be fully equalized either by applying pressure in the tubing from the surface or by running a prong to allow equalization from below. The valve will reopen when the tubing pressure acting on the internal piston area overcomes the dome charge. Applications » Wells producing large volumes of abrasive fluids » Wells with declining bottomhole pressure » Wells with no provisions for surface-controlled valves Features » Large bore not restricted by a flow bean » MTM ball and seat » Designed to resist pressure surges *description excerpted from manufacturers catalogue.

Storm Choke® K safety valves are ambient-type, wireline retrievable valves with the largest flow area of all direct controlled safety valves on the market. They are ideally suited for high-volume, low-pressure wells. These valves are normally closed and pre-charged with a set dome pressure. When the well flowing pressure drops below the predetermined dome-pressure charge because of a rupture in flowline or surface equipment, the dome pressure and main valve spring close the valve, shutting in the well below the earth’s surface. This valve contains a detent mechanism to provide a positive snap-action closure at the predetermined disaster rate of the valve. Its bore is not restricted by a flow bean. The valve is designed to resist pressure surges. A metal-to-metal poppet valve and seat comprise the valve’s primary closure mechanism. The K valve is ideal for protecting wells with declining bottomhole pressure. This valve closes in situations where a pressure decline would not activate a valve with a flow bean. To reopen the valve, the operator must fully equalize pressure either by applying pressure in the tubing from the surface or by an equalizing prong. The valve will reopen when the tubing pressure acting on the internal piston area overcomes the dome charge.

An annular vent sleeve valve communicates between the casing annulus and producing formation. The valve is a hydraulically operated sliding sleeve device like a surface controlled subsurface safety valve with a hydraulic piston and a power spring to maintain the valve in a normally closed position. The valve is used with a bull plug on top or as an annular safety valve by providing annular bypass while control pressure is applied. With an electrical feedthrough device, this valve functions through a single packer mandrel as an electric power cable passage and annular bypass. On a dual hydraulic packer, the valve operates by a common hydraulic control line that sets the packer and operates the tubing-retrievable safety valve. Hydraulic pressure from the control line shifts the valve open to create a flow path across the packer in the annulus. Spring force closes the valve upon loss of control-line pressure to the piston. If the valve becomes inoperable or closed, an emergency shear feature allows fluid to be pumped into the producing formation from the annulus. Applications » Gas lift and electric submersible pump situations Features » Accurate fluid level shot during pumping because of large ported area through the vent sleeve » Maximum gas vent flow area allows increased gas flow rates and lower circulating pressures » Valve will shut off flow from either direction — production or injection *description excerpted from manufacturers catalogue.

The AV annulus safety valve is a fully retrievable high performance annulus safety system packer with integral annulus safety valve. The system provides annular bypass through a hydraulically operated poppet valve. The AV system is run in a single trip in conjunction with a setting sub that can be shifted for hydraulic tubing-set or can be alternatively control-line set from surface. Applications The AV system is used for controlling annulus fluids in gas lift applications, monitoring of annulus pressures in critical situations, and in one- or two-trip annulus safety system completions. The completion can be run to depth and set with the surface tubing hanger flanged up. It can also be used in completions in which spacing out against a subsurface tubing hanger is required (i.e., no elastomeric expansion joint necessary). The tailpipe can be left in either tension or compression. The system can be used where high tensile loads and pressure differentials exist with the completion anchored in unsupported or poor condition casing. Features » Interlock system prevents preset » Tubing test facility while running » Hydraulically set in one trip on tubing with no mandrel movement » Annulus-mounted release mechanism » Internal/external components rotationally locked together » Element anti-extrusion system » One-trip system allows multiple control-line bypass » Premium thread connections — no elastomeric seals tubing to annulus » Primary release method is applied tubing pressure using dedicated punch release tool on slickline » Secondary release method available with simple tubing cut *information collected from manufacturer literature
