A Precision Punched Slot screen is a high performance technology used in sand control. PPS is a proven alternative to using slotted liner.  It is also suitable for coarse sandstone formations and open hole horizontal wells.


PPS is composed of an API base pipe, which is perforated to customer specifications. The stainless steel jacket is punched with precision slots, which are specific to the demands of the customer well formation.



Open area is 3 to 5 times larger than slotted liner

High self-cleaning capability from side flow slots

Base pipe has a higher mechanical strength than slotted liner

Anti-corrosive high quality stainless steel screen

O.D. is smaller than coupling, thus safe and easy to run in open hole horizontal well

Tolerance of 0.05mm on machining
