Well screen definition

Well screen or "screen" means a manufactured intake structure with uniform openings designed to retain the aquifer formation, prevent collapse of the borehole adjacent to the screen, and accommodate a yield adequate for the intended use of the well.
Well screen means a filtering device (e.g. manufactured perforated pipe) used as a sediment filter allowing entrance or exit of sub-surface fluids.
Well screen means a device, usually made of plastic or metal that is capable of preventing unconsolidated or poorly consoli- dated geologic material from entering the well. The size of the mate- rial which is prevented from entering the well is predetermined and controlled by the screen opening or slot size of the screen. A well screen may include a riser pipe.
