- Parveen Industries delivers custom gravel pack solutions for Nigeria’s upstream sector.
Niger Delta Reality: High Potential, High Sand Risk
Nigeria remains one of Africa’s leading oil producers, with the Niger Delta contributing the majority of its output. According to the Nigerian Upstream Petroleum Regulatory Commission, the region holds vast reserves but faces significant production challenges, particularly sand ingress.
Why Sand Production Is a Major Issue
- Unconsolidated sandstone formations
- High flow rates leading to formation destabilization
- Weak grain bonding in reservoirs
Operational Impact
- Erosion of downhole and surface equipment
- Blockage in tubing and flowlines
- Frequent well shutdowns and costly interventions
In such conditions, sand control is not optional—it is essential for sustained production.
Gravel Pack Systems: The Gold Standard for Sand Control
Gravel packing involves placing sized gravel between the wellbore and a screen to filter out formation sand while allowing hydrocarbons to flow.
Core Functions
- Prevent sand entry into the wellbore
- Stabilize the formation
- Maintain consistent production rates
Parveen Industries offers engineered gravel pack equipment designed for:
- High-efficiency filtration
- Long-term durability
- Compatibility with complex well conditions
