Abstract
A downhole system includes a tubular having an outer surface and an inner surface defining a conduit. A terminal member is connected to the tubular. A first screen system including a first screen housing is mounted to the tubular adjacent the terminal member, and a second screen system including a second screen housing is mounted to the tubular and spaced from the first screen system. The second screen system includes a beta blaster valve operable to selectively open flow into the conduit based on a pressure differential between the first screen system and the second screen system.
