Produced Water Treatment in the Oil & Gas Industry

Produced water is water generated from a well during oil and gas production. While it has historically been injected into deep wells, recycling is increasingly preferred. Ecologix offers two approaches for recycling produced water.

For highly mobile, high-volume treatment, the ITS-1500 is a complete system on a frac-tank chassis. It includes a multi-compartment chemical reaction tank, mixers, enhanced dissolved air flotation for sludge separation, a clearwell, chemical feed pumps, and PLC controls.

For high treatment volume in a compact footprint, Ecologix offers skidded E-DAF solutions. These can include an oil-water separator, chemical reaction tank, enhanced dissolved air flotation system, activated glass filtration, and power distribution and circuit protection. These systems can treat up to 126,000 barrels of water per day (5.29 MGD).

ITS and skidded E-DAF systems are designed for remote, challenging environments and can be remotely monitored, with certain functions remotely operated when needed.

An efficient treatment system can allow near-100% reuse of produced water, reducing fresh-water use and downtime in water-sensitive districts.

Ecologix has experience recycling produced water and frac flowback in west Texas and other North American mining areas. Key benefits include:

• Brine water can replace fresh water in frac-fluid mixtures.
• Fresh-water resources can remain untouched in fracking operations.
• Water transport trucking can be reduced by hundreds of loads per well.
• Savings can reach $100,000 or more per well.
• Using brine water can prevent clay swelling and support well productivity.
