Results, measured in mg/L.

Every WFS project is contracted to a written outlet specification. These reference cases show the water-quality step-change achieved on real produced-water streams.

Case 1

Reinjection-grade produced water for a mature onshore field

A rising-water-cut onshore field needed injection water that would not plug the formation. A WFS train combining separation, flotation, media filtration and polishing brought a heavily oily feed to full reinjection spec — and held it.

ParameterFeedTreated
Oil-in-water (OIW)~2,500 mg/L<5 mg/L
Total suspended solids~300 mg/L<2 mg/L
Silt Density Index (SDI)Not injectable<3
Case 2

Sour produced water with high H₂S

A sour field produced water carrying several thousand mg/L of H₂S alongside high chlorides. WFS delivered the full sour-service train in high-alloy, NACE-compliant materials with safe vent-gas disposal.

ParameterFeedTreated
Hydrogen sulphide (H₂S)Several thousand mg/L<1 ppm
Oil-in-water (OIW)High, variable<5 ppm
Vent gasUncontrolled sour ventRouted to VGCU
Case 3

Produced water reuse in a water-scarce region

Instead of deep-well disposal, produced water was polished through ultrafiltration and reverse osmosis to reuse grade — cutting disposal energy and freshwater draw at the same time.
