SYSTEM AND METHOD FOR CONTROLLING SAND PRODUCTION IN WELLS

摘要

A technique is provided for controlling sand in a well. The technique may utilize a vent screen assembly having a main screen, a vent screen, and a tubular member extending from the main screen to the vent screen. An expandable element is positioned around the tubular member between the main screen and the vent screen. After the vent screen assembly is deployed into a wellbore, a gravel pack can be formed around at least the main screen. The expandable element is selectively expanded in a radial direction to secure the gravel pack and to enable higher production rates.
