    Patent number: 7665535
    Abstract: A one-trip system for use in a subterranean well includes a tubing hanger, a production tubing, a perforating gun assembly and a screen assembly. The tubing hanger is adapted to be mounted to one of a well in the well casing near the earth's surface. The production tubing is sealingly attached to the tubing hanger, and the perforating gun assembly is coupled to the production tubing. The tubing hanger, production tubing, perforating gun assembly and screen assembly are adapted to be run downhole as a unit. Once the unit is positioned downhole the screen assembly is adapted to be moved relative to the production tubing by a riglessly-deployed continuous medium that is deployed through the production tubing from the surface of the well.
