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.

Downhole shunt tube isolation valve system

A multi-functional well completion apparatus and method of operation thereof that offers the ability, in a single trip and with limited running tool manipulation, to perform downhole completion operations, such as gravel pack operations or sand control frac or other fluid stimulation operations is described. The well completion tool has multiple functions or operational positions by using a self-closing time delay valve without the need of service tools, thereby saving rig time, reducing operating costs and operational risks associated with tripping service tools into and out of a wellbore.

Multiple system ports using a time delay valve

Methods to dehydrate a gravel pack and to temporarily increase a flow rate of fluid flowing from a wellbore into a conveyance are disclosed. A method to dehydrate gravel pack includes deploying a valve at a location proximate a gravel pack. The valve includes a rupture disk that ruptures in response to a threshold amount of pressure, and reactive fluid that actuates the valve to a closed position. The method also includes providing a fluid flow path from the gravel pack to the conveyance. The method further includes closing the valve after providing the fluid flow path from the gravel pack to the conveyance for a threshold period of time.
