Abstract
A downhole shunt tube isolation system having a fluid channel and a piston hydraulic chamber disposed within a valve actuator housing, wherein the fluid channel is sealed via a plug to hydraulically lock a valve in an open position, wherein a gravel slurry is configured to flow from a first tube segment through the valve to a second tube segment when the valve is in the open position. A portion of the plug is displaced to open a fluid path through the plug to the piston hydraulic chamber, wherein opening the fluid path to the piston hydraulic chamber hydraulically unlocks the valve, closing the valve via a biasing force to block the flow of the gravel slurry from a first tube segment through the valve to a second tube segment.
