*Slotted Liner VS Perforated Liner

Both slotted liner and perforated liner are typically used for sand control in a wide range of well completions. They can be used alone as sand exclusion devices in openhole completions in high-permeability and well-sorted formations, or just used as a base pipe to offer higher strength and collapse resistance.

The differences between slotted liners and perforated liners are hole size and shape. Slotted liner is designed with finer slots of 250-1800 μm in width, while perforated liner owns round holes of 12-25 mm in diameter commonly. Thereby they are applied for sand control in formations with different grain sizes.
