with $20B market capitalization
based out of Texas, USA

CGE & SCE systems

Customer Need:

Provide water for field development according to
the drilling and completions schedule in a safe,
reliable and cost effective manner through a
produced water treatment and reuse program
(Design-build-own-operate-maintain).

Treatment Requirement:

Treat 12,000 barrels per day of influent to deliver:

  • 2,000 barrels per day of fresh water (TDS removal)

  • 9,000 barrels per day of  clean brine (De-oiling,
    disinfection, solids and turbidity control,
    hardness and scaling control, pH adjustment)

  • 1,000 barrels per day of 10-lb brine

Operation:

  • Clean brine TSS < 25 ppm, O&G < 25 ppm, Fe < 5 ppm

  • Bacteria 460 MPN/ml

  • Recovery ratio greater than 99.7% w/w

  • Solid waste produced less than 0.3% w/w

Operational Metrics:

  • Fresh Water Recovery at 100,000 mg/L TDS > 60%

  • Fresh Water Recovery at 150,000 mg/L TDS > 40%

  • Water quality statistically monitored to be within
    prescribed effluent limits at all times

  • Solid waste disposed at appropriate landfill All
    effluent reused within oil and gas operations

  • Utilized natural gas as energy source
