ProdSep™ │Produced Water Treatment Technologies
Integrated Solutions for Complex Water Challenges
HyO-RO™ | Hybrid Osmosis, Enhanced Recovery
Produced water, a byproduct of oil and gas extraction, often comprises a complex mixture of formation water, injected water, and trace amounts of hydrocarbons, salts, heavy metals, and treatment chemicals. Its management represents a significant operational, regulatory, and economic challenge for petroleum producers.
While some produced water is re-injected for enhanced oil recovery (EOR) or disposed of in deep wells, a growing volume requires treatment — either to meet increasingly stringent environmental discharge standards or to enable beneficial reuse, such as:
- Agricultural irrigation (after desalination and contaminant removal)
- Industrial process water or cooling tower make-up
- Surface water discharge (with appropriate decontamination)
- Fracturing fluid make-up (for closed-loop reuse)
- Potable or non-potable municipal applications (in advanced scenarios)
ProdSep™ is InfraCorp’s dedicated produced water treatment platform, engineered to transform one of the oil and gas industry’s biggest liabilities into a strategic asset. Whether for reuse, reinjection, or discharge, ProdSep™ empowers producers to meet regulatory, operational, and sustainability goals with confidence.
