Abstract
A technique enables an improved filtering of sand, a desired distribution of produced or injected fluid, and a reduction in erosion of completion components positioned in a production or injection well. The technique employs a base pipe and a sand screen surrounding the base pipe. The base pipe comprises a plurality of flow restriction elements arranged in a selected pattern along the base pipe to provide a desired distribution of the fluid flowing into or out of the sand screen. The pattern of flow restriction elements also maintains a flow rate of the flowing fluid below an erosive flow rate across the entire sand screen.
