Abstract
A technique facilitates formation of a gravel pack. A well completion is provided to facilitate improved gravel packing during a gravel packing operation and subsequent production. The well completion is constructed to freely return a gravel pack carrier fluid through a base pipe during gravel packing. A valve system is positioned to enable restriction of fluid flow into the base pipe following the gravel packing operation. The valve system may be selectively actuated to restrict the fluid flow into the base pipe via a signal such as a pressure signal or timed electric signal.
