A client required assistance with produced water storage for a natural gas operation in a remote location. The operation focuses on producing natural gas and demands a robust solution for handling large volumes of brine wastewater.
Challenge
The project required a substantial produced water storage capacity of over 150,000m3 – almost 1 million barrels. The solution needed to be efficient, quick to deploy and meet a high environmental containment standard.
Solution
Two 78,000m3 Concept Tanks were safely deployed and featured several key design elements tailored to the project’s unique requirements:
- Multi-layered liner System: The tanks were equipped with two 40 mil Enviro Liner® geomembrane containment layers integrated with a Geovolt® conductive geotextile intermediate layer to enable accurate liner integrity testing before the tank’s operation. This feature ensured the integrity of the liners at any water level, addressing the challenges posed by evaporation in extreme climates.
- Tank Monitoring: Radar level sensors were installed on the tanks, monitoring fluid volumes remotely and allowing for real-time data collection and management of the tanks’ conditions.
- Integrated Leak Detection: The tanks incorporated a closed-loop leak detection system, which provided added durability compared to conventional options. This design choice was crucial for maintaining the tanks’ functionality and longevity in the harsh environment.
- Operational Features: Each tank also featured HDPE over-wall inlets and outlets, aluminum viewing platforms, and emergency egress ladders.
Outcome
Concept Tanks successfully delivered a robust and efficient brine storage solution that met the client’s needs and project requirements. This significant addition of storage capacity increased the water management network’s flexibility and redundancy, allowing for ongoing and uninterrupted production.
Conclusion
This project highlights Concept Tanks’ expertise in delivering tailored solutions for complex environmental challenges. By leveraging technology and innovative design, Concept Tanks provided a reliable and efficient brine storage system, ensuring the client’s operational needs were met and they would benefit from the solution for years to come.
