Hydraulic-line downhole wet-mate connector
Deploy a multitrip intelligent completion with hydraulic equipment in the lower completion.
Control production and injection in intelligent completion systems with the TRFC-HD dual-line, multiposition interval or flow control valve (formerly called the Odin valve). By deploying multiple valves, you can selectively control flow from different reservoir zones.
Two hydraulic control lines operated from surface activate the downhole choke section. In multiple-valve completions, each valve has a dedicated open line while the single close line is shared among all.
The rugged design makes the valve suitable for severe environments with scale deposits, erosion, and other demanding conditions. Setting depths are almost unrestricted because of the fully balanced piston design.
These flow control valves are available in various materials to suit a wide range of oil, water, and gas applications, including high-flow-rate production and injection wells with multizone or commingled-flow completions and natural-gas-lift completions. The valve can handle up to 70,000 bbl/d of liquid when fully open.
Two versions of the TRFC-HD valve are available—annular and inline. The annular valve controls flow between the tubing and annulus. The inline valve controls flow inside the tubing by using a shroud and retrievable plug design. In production applications, the plug is located immediately below the choke section, while in injection applications it is located immediately above. Flow is diverted by the plug into the shroud and reenters the tubing through the choke. The TRFC-HD valve features eight positions in its standard configuration, including fully open, fully closed, and six intermediate choking positions. However, the number of positions and the choke area at each position can be adapted to meet requirements.
WellWatcher permanent monitoring systems can be deployed in conjunction with the valves to monitor downhole pressure and temperature for a better understanding and more precise control of the reservoir in real time.
