The slotted liner screen works by allowing certain particle size coming through the surface with crude oil while keeping the bigger size sand staying outside, and thereby the anti-sand purpose is achieved.
Slotting Patterns: Line slot pattern, staggered slot pattern, multiple staggered slot pattern.
- The slotted liner is a robust and cost-effective solution for long completions or low productivity wells.
- We offer slotted liners in wide range of slotting patters to satisfy the requirement for different open area.
- High rigidity, high intensity, excellent anti-corrosion and even distribution of pressure.

The machining consists of cutting rectangular openings with small rotary saws. Routine slot widths are 0.030 in. or larger. The minimum slot width that can be achieved is about 0.012 in. Slots that cut less than 0.020 in. in width involve high costs because of excessive machine downtime to replace broken saw blades that overheat, warp, and break.
