Gas Vent Valve
The Gas Vent Valve is designed to be threaded onto PRH4 ESP packer and vent the gas to maintain optimum fluid levels for the ESP. It is a control line actuated valve from surface. The valve is opened by applying hydraulic control pressure, and closes when the pressure is released.
- Controlled by hydraulic control-line pressure
- Sealing reliable and long service life
- Large flow area
- Two sizes: 1” and 1 1/2”, c/w 1/4” NPT connection
- 5000psi working pressure rating
The Cable Pack-Off provides an effective seal for an electrical submersible pump (ESP) cable when used with a multistring packer. To achieve a seal, the metal shield on the cable is removed from a short section, and the cable is installed through the secondary side of the ESP packer. The tool isolates pressure below from pressure above the packer by sealing on the rubber jacket of the cable.
- Compression energized elastomeric seals
- Without splicing or using expensive penetrators when running cable through the packer
- Seals on cable OD, designs available for round and flat cables
- Simple tighten of a nut to compress the elastomers
- Standard 3000psi working pressure rating
The Model Hydro Trip Pressure Sub is a pressure actuated device installed in tubing string below a hydrostatically actuated tool such as a Hydraulic set packer. It provides a method of applying pressure to activate and set the packer and then through continued pressure, activate the Hydro Trip Sub. Packer is set by circulating a ball through packer down to ball seat in the Hydro Trip Sub.
After packer is set, a continued increase in pressure is applied to shear the shear screws in the shear ring, allowing the ball seat collet to move down into the collet relief area and allowing the ball to pass down the Hydro Trip Sub through the tubing, leaving a “full open” Sub with no restrictions to production. The Collet Catcher Sub is used when any restrictions are installed below, ball and solid bar are available.
The Y-Tool is designed to be run with ESP below ESP packer. As the produced fluid leaves the ESP it flows through a pump sub and then joins the main production string through the Y-Tool profile that has been carefully designed to minimize flow erosion. The Y-Tool offsets the ESP in the well to provide a straight line conduit for wireline or coiled tubing tools to bypass the ESP. The Y-Tool has an upper connection for the production tubing and two lower connections, one for the ESP and the other for the bypass. A blanking plug is located in the bypass side in a special nipple to prevent recirculation of the pumped fluid. The blanking plug is removed prior to and after intervention. For logging operations, the blanking plug is replaced by a logging plug which allows real time or memory logging to be conducted whilst the pump is operating.
- Large flow area
- Minimize flow erosion
- Simple design
- Standard 2 3/8”, 2 7/8” and 3 1/2” sizes
Control line and Cable Protectors
The Control Line and Cable Protectors fix the cable on tubing, and it protects the cable. The tubing supports the control line and cable and ensures they not be destroyed while running the string. Consequently, the control line and cable could be used again and the cost is reduced. Negative effects would occur if the cable were not protected while running the string. Such as attrition, changing pump and well repair work. Especially the big diameter cables are more easily damaged at the coupling.
- Different size for tubing
- Anticorrosion material capable
- Special tools for right installation
- Record the torque and position
- Guard against falling objects
