Retrievable Wireless Subsurface Safety Valve System

Restore oil and gas wells and recover production after a safety valve failure

Restore operating or shut-in wells
Declining wellbore intervention costs in recent years makes the operation economically attractive for operators to restore well production.
Fix downhole safety valve problems
Well integrity issues in operating or shut-in wells are due mostly to problems with subsurface safety valves (SSSVs).
Gain production returns with intervention
Repairing or maintaining downhole valves can return significant value, both financially and hydrocarbon volumetrically.
Regain control and produce optimally
Controlling the safety valve from the surface enables optimal well production regardless of the downhole flowing regime.

Get your well back online or back on track

With the decline in number of operating wells in recent years due to shut-in or temporary plugging, restoration is crucial to return this well stock to operation or risk permanent abandonment.

Wirelessly fix the downhole SSSV and regain control from the surface

GEM-Valve system enables remediation without relinquishing control of subsurface safety shut-in equipment via wireless surface control of the valve, allowing reliable and regulatory compliant production of oil and gas wells.

Installed as a temporary safety valve solution, the system eliminates production deferral while workover intervention planning and sourcing activities take place. Installed as a permanent solution, it eliminates significant workover repair and recompletion costs, which might not be justifiable for old producing wells in mature fields.

Operate without a hydraulic control line or cable

Controlled to stay open from surface, the GEM-Valve safety valve system is largely tolerant to downhole flow and pressure variations, which are responsible for frequent undesired valve closures of alternative remediation solutions such as subsurface-controlled safety valves.
