Slotted liner is a type of sand control completion technique used in oil and gas wells to prevent sand and other particles from entering the wellbore while allowing hydrocarbons to flow into the wellbore.

Slotted liners are often used in unconsolidated or poorly consolidated reservoirs that are prone to sand production. The slots on the liner are sized to prevent sand particles from entering the wellbore while allowing the oil or gas to flow through the slots and into the liner.

Slotted liners are commonly used in combination with gravel packing, which involves filling the annulus between the liner and the formation with gravel to provide additional sand control. Together, slotted liners and gravel packing can help to prevent sand production and maintain long-term well productivity.
