The wire retrievable safety valve (WRSV) has the same function as the tubing safety valve - shut-in in an emergency. Install in a pre-run special landing nipple or tubing-retrievable safety valve with a lockout func- tion. Compared with the traditional safety valve, the WRSV only need cooperate the slickline equipment to retrieving and re-running. Regular maintenance or emergency replacement of downhole control systems can be performed when the rig is not available, or surface equipment is limited.
Features and Benefit
Need to be used with special landing nipple or with the lockout function of the safety valve
Same pressure rating as the tubing retrievable safety valve
Complete metal-to-metal well containment in the closed position (body/seat connections and flapper)
Retrieve maintenance and re-running does not require retrieving of tubing string
Applications
General production completions with surface equipment limited
