Abstract: A technique facilitates control over flow of fluid in a variety of well applications and other applications. A flow control device is used to automatically control flow of fluids based on viscosity of the fluids. For example, the flow control device may be used to automatically allow flow of oil while blocking flow of gas and/or water. According to an embodiment, the flow control device comprises a production circuit and a metering circuit. The production circuit and the metering circuit cooperate to allow flow of a well fluid with a first viscosity and to block flow of well fluid when the well fluid has a different viscosity, e.g. relatively lower viscosity.

Abstract: A technique facilitates performance of a gravel packing operation and desired zonal isolation. An apparatus, e.g. a sliding sleeve shunt tube isolation valve, may be deployed downhole and configured to facilitate a gravel packing operation and zonal isolation. By way of example, the apparatus contains a conduit which in an open position allows the flow of gravel pack slurry and in a closed position creates a barrier. In the closed position, upper and lower portions of the conduit are isolated from one another. When the apparatus is coupled with a packer and sand screens, the apparatus serves to create complete zonal isolation in, for example, an open hole alternate path system.
