1. Sand-Prone Reservoirs

• GRE screens are used in reservoirs with high sand content to prevent sand from entering the wellbore.
• They enhance production flow and reduce wear on downhole equipment.

2. Sour Oil and Gas Wells

• Ideal for wells containing corrosive gases like hydrogen sulfide (H₂S) and carbon dioxide (CO₂).
• Provide long-term corrosion resistance, ensuring operational reliability.

3. High-Salinity Environments

• GRE sand screens are highly resistant to high-salinity formation water, making them suitable for offshore oilfields and saline land reservoirs.

4. Deep Wells and High-Pressure Wells

• Their excellent pressure resistance makes GRE sand screens suitable for deep and high-pressure well environments.

5. Multi-Zone Sand Control

• GRE sand screens are effective in multi-zone sand control applications, preventing cross-layer contamination and maintaining wellbore integrity.
