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 plas- tic or metal that is capable of preventing unconsolidated or poorly consolidated geologic material from entering the well. The size of the material 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.
