Sour produced water, handled safely — H2S to below 1 ppm.
Sour gas and sour oilfields (Shah, Karan/Hasbah, West Qurna) produce water with H2S reaching several thousand mg/L plus high chlorides and TDS. WFS designs the full sour-service train — in high-alloy materials — to strip H2S, remove oil and solids, and safely dispose of the vented gas.
Feed handled and treated targets
| Parameter | Feed handled | Treated target |
|---|---|---|
| Hydrogen sulphide (H2S) | up to ~5,000 mg/L | < 1 ppm |
| Oil-in-water (OIW) | up to ~3,000 mg/L | < 5 ppm |
| Total suspended solids | up to ~400 mg/L | < 5 ppm |
| Chlorides / TDS | high (sour-service MoC) | Managed for reinjection |
