Mill slots are an effective type of perforation that can function similarly to a well screen. They are designed with slots that allow water to enter while filtering out larger particles, thus serving a purpose akin to that of a well screen, which is intended to protect the well from sediment while permitting water flow. Mill slots are created by milling a series of narrow cuts into the material of the well casing, which provides the necessary openings for effective water entry while maintaining structural integrity.

Other options may not provide the same balance of water entry and filtering capabilities as mill slots. Laser cuts can create precise holes or slots, but their filtering capability may not match that of mill slots. Diamond perforations and socket cuts may serve different purposes or applications in constructions and do not mimetically replicate the function and design characteristic of traditional well screens quite as effectively.
