Case Study Vår Energi Saves Millions with Industry’s First Subsea Retrofit Multilateral Wells
RapidX junctions deliver access to subsea reservoirs and individual control without additional infrastructure.
Premium tubing-retrievable, surface-controlled safety valves
The premium rod piston system in these valves uses a reliable, spring-energized filled Teflon sealing element. Operating within the valve's chamber housing, the system comprises a stepped OD; a compliant downstop of polyetheretherketone polymer; a static, full-closed metal-to-metal seal; and an integrated piston centralizer.
For maximum reliability, all TRM-4 and -4H valves have only two body joints and use proprietary threads to achieve a solid, metal-to-metal seal. The premium flapper mechanism also has full metal-to-metal sealing plus a secondary soft seat, and it meets a leakage-acceptance criterion that is substantially more stringent than API and ISO specifications.
A unique lockout mechanism enables a simple slickline procedure to permanently lock the valve open and initiate secondary hydraulic communication. A second option enables locking open the valve without activating secondary hydraulic communication.
