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.

Abstract: A technique facilitates actuation of a packer to a sealing and gripping position along a borehole. The packer includes a packer element structure mounted about a center structure. The packer element structure includes a sealing element mounted along an expandable base such that the sealing element may be radially expanded. Additionally, the packer includes an actuator member connected to a portion of the packer element structure via a release mechanism, e.g. a shear member. A plurality of slips may be located on the actuator member such that linear movement of the actuator member causes successive movement of the packer sealing element and then the slips in the radially outward direction. The packer may be constructed such that this sequential setting motion creates a jarring effect to ensure the slips securely bite into the surrounding wellbore surface, e.g. casing surface.
