We offer multiple slot designs to match your sand control needs:

 

Straight Slots: Cost-effective, uniform design, suitable for moderate sand conditions.

 

Keystone Slots: Tapered shape prevents plugging and offers superior sand retention.

 

 

 

 

Patterns include straight-line, staggered, and gang (multi-staggered) layouts. The gang pattern is ideal for high-torque and thermal applications such as SAGD wells.

 

 

 

 

 

1. Improves well integrity and inflow performance
2. Reduces sand-related damage and downtime
3. Compatible with various threading types (STC, LTC, BTC, NU, EU, etc.)
4. Durable construction available in multiple steel grades
