Gas Ingress Isolation Valve
Prevents gas returning to control unit
The Gas Ingress Isolation Valve (GiiV) is an automated system designed and manufactured by Oilenco to prevent hazardous gas ingress during tubing retrievable subsurface safety valve (TRSSSV) failure. The GiiV is installed in-line on the hydraulic control line and isolates the TRSSSV from the surface control equipment. It contains an internal piston that is held open by hydraulic pressure during normal TRSSSV operation. If the downhole TRSSSV fails due to issues like a stuck open flapper or damaged seals, gas ingress into the control line causes a pressure reduction. This triggers the GiiV piston to automatically close, sealing off the failed TRSSSV. The GiiV activates without any operator intervention, preventing dangerous gas returns to the surface. Its passive operation and quick installation provides a safe, long-term solution to manage TRSSSV gas leakage without requiring repeated wireline interventions. The GiiV allows operators to safely return wells with leaking safety valves to production.
