API 5CT 4 Inch Slotted Liners

Due to the ease of installation and lower costs when compared to well screens, slotted liners are a popular choice in many different production environments.

In consolidated formations, perforated and slotted liners with larger slots are run to stabilize the wellbore and provide a large flow area. These downhole characteristics are often present in geothermal wells.

In unconsolidated sand formations with gravel pack or large enough grain sizes, liners with slots of minimum width provide effective sand control and continuous flow of production fluids.
