Patent ID: 8752625

Claim:
A gravel pack system for use in a wellbore, comprising: a screen assembly to filter particulates, the screen assembly being disposed around a completion string tubular; an isolation device disposed about the completion string tubular and configured to sealingly engage an inside surface of the wellbore thereby isolating a first wellbore zone from a second wellbore zone; a first shunt tube disposed between the completion string tubular and the inside surface of the wellbore, the first shunt tube extending through the isolation device; a second shunt tube disposed between the completion string tubular and the inside surface of the wellbore, the second shunt tube positioned below a lower end of the first shunt tube; and a swellable element disposed about the completion string tubular below the isolation device and between the lower end of the first shunt tube and an upper end of the second shunt tube, the swellable element configured to swell in response to an input stimulus to sealingly engage the inside surface of the wellbore, wherein the swellable element, once swelled, prevents fluid communication between the first and second shunt tubes and between the first and second wellbore zones.
