Is the statement true: The mesh size of the screen is determined by the size of the aquifer material?

• A. True
• B. False
• C. Not sure
• D. Not applicable

Answer: (A)

The main idea is that the screen acts as a filter at the well intake, so its openings must be sized to stop the formation particles from entering while still allowing water to pass. Because the aquifer’s grains determine how easily sand or solids could migrate toward the screen, the screen’s mesh size is chosen to match those grain sizes. If the aquifer contains larger grains, you select openings that are small enough to block those grains; if the formation is finer, you use a finer mesh. In short, the mesh size is dictated by the size of the aquifer material to prevent solids from entering the well, while preserving flow.
