Pre-pack well screen.Jacket slot size between 0.15mm to 15mm.The pipe base screen are used for deep water well application and oil field application It is used for sand control in wells with high pressure and high traction value due to the depths.
The filter pack provides both filtration and stabilization of the screen. The main objective of filter-packing is to install material more permeable than the native formation into the area immediately around well screen.
