In developmentPatent pending Box-RO Produced Water Treatment

Turn produced water into usable water.

Every barrel of oil comes up with water, and most of it gets trucked off and injected. Box-RO is a containerized treatment plant built to clean that produced water right on location, so it can go back to work for drilling, completions and operations instead of down a disposal well.

The produced water problem

The water comes up with the oil. We want to put it back to work.

Produced water is the largest waste stream in the oilfield, and moving it is one of the biggest trucking jobs in the patch. At the same time, operators haul in fresh water for drilling and completions. Box-RO is designed to close that loop on site, with a second line that makes drinking water for the camp.

Produced water line

600m³/day

Reuse water for operations

Feed: produced water from the well, after oil separation
For drilling, completions, turbine wash, cooling and washdown
Non-potable, 500–2,000 mg/L TDS

Camp line (bonus)

400m³/day

Drinking water

Feed: brackish groundwater
Designed to EPA drinking-water standards (<500 mg/L TDS)
Remineralized and disinfected with UV and chlorine

How it works

From produced water to usable water in six steps.

IntakeProduced water from the separator or tanks; brackish groundwater for the camp line

PretreatHydrocyclone, gas flotation and walnut-shell filters strip residual oil, then fine filtration

Reverse osmosisHigh-pressure, two-stage membranes with energy recovery

PolishRemineralize and disinfect for drinking; optional biocide for utility

Store & deliverSeparate drinking and utility tanks feed the camp and the job

Brine handlingConcentrate to a lined evaporation pond or disposal well

Pad footprint about 35 × 25 m including tanks. Layout is a concept and is subject to detailed design.

Built for the patch

Designed for dust, heat, cold and hard trucks.

Mobile by designStandard containers that move by truck, skid or crane with minimal site work. Moving heavy equipment is what we already do.
Oilfield-rated enclosuresInsulated, HVAC and dust filtration, −10 to +45 °C operation, hazardous-area electrical where required.
Water as a servicePlanned as an operated service with remote monitoring, so operators buy water, not a plant.
Less disposal, less fresh waterEvery barrel reused is a barrel not trucked to injection and a barrel of fresh water not hauled in.

Patent pending. Box-RO is in front-end engineering design and has not yet been built. All figures are design targets from preliminary engineering. Drinking-water output is designed to EPA standards and will require third-party certification (NSF/ANSI 61) before potable service. Produced-water suitability depends on salinity and chemistry and is confirmed site by site; very high-salinity brines may require additional treatment.
