SLOTTED LINER
Slotted liner is actually a kind of sand control screen, chiefly used as the water and oil reservation layer for sand control. Its major function is to prevent rock pieces dropping into the water or the oil well. This type of slotted product is commonly used in sand control devices, especially useful for horizontal wells.
