75,000 BPD Produced Water Desalination — Permian Basin, Texas
Midland Basin, Texas, USA
Results Achieved
85,000 → 210 mg/L
TDS Reduction
$18M/year
Disposal Cost Savings
68,000 BPD
Freshwater Offset
A large Permian Basin operator faced escalating produced water disposal costs as nearby injection well capacity approached its limit. The produced water (TDS ~85,000 mg/L with high Ba²⁺, strontium, iron, and NORM) required desalination for beneficial reuse in hydraulic fracturing — saving both disposal and freshwater sourcing costs.

Offshore Platform Produced Water — MARPOL Compliance Upgrade, North Sea
Norwegian Continental Shelf, North Sea
Results Achieved
<12 mg/L
Outlet OiW Achieved
280 tonnes
Platform Weight Impact
A Norwegian-sector offshore platform was failing tightened OSPAR MARPOL discharge limits of <30 mg/L oil-in-water. The existing deoiling hydrocyclones could not keep up with the changing oil-to-water ratio as the field matured. Platform space and weight were severely constrained (350-tonne budget).

Refinery Major Turnaround Wastewater — Saudi Arabia
Jubail Industrial City, Saudi Arabia
Results Achieved
11,800 m³/day
Peak Flow Handled
100%
Regulatory Compliance
Zero days
Turnaround Delay (water)
A 400,000 BPD Saudi refinery required a 6-week turnaround across 8 process units. Wastewater flows were expected to peak at ~12,000 m³/day — roughly 8× normal — and contained hydrocarbons, caustic, spent cleaning chemicals, and heat-exchanger fouling products that exceeded the existing ETP capacity.

SAGD Produced Water Recycling — Fort McMurray, Alberta
Athabasca Oil Sands, Alberta, Canada
Results Achieved
98.2%
Water Recycling Rate
<0.4 mg/L
Silica (OTSG feed)
92,000 m³/month
Freshwater Reduction
+7.3%
Steam Generation Efficiency
An Alberta oil sands SAGD operation needed >95% water recycling to reduce freshwater consumption and improve steam-generation efficiency. High-temperature, high-silica produced water had to be treated to OTSG boiler feed quality — silica <1 mg/L, hardness <0.1 mg/L — a spec traditional cold lime softening could not consistently hit.

Spent Caustic Treatment Plant — Kuwait Refinery
Kuwait City, Kuwait
Results Achieved
>99.99%
Sulfide Destruction
180,000 → 150 mg/L
COD Reduction
$4.2M/year
Hazardous Waste Savings
A Kuwait refinery generating 800 m³/day of spent caustic (NaOH) from LPG merox treating was sending all spent caustic off-site to hazardous waste contractors at significant cost. The caustic contained sulfides (~3,000 mg/L), disulfides, phenols (~800 mg/L), and mercaptans — incompatible with the refinery's existing biological ETP without pre-treatment.

Shale Gas Frac Flowback Mobile Treatment Fleet — Marcellus Shale
West Virginia & Pennsylvania, USA
Results Achieved
96% (vs 12%)
Water Reuse Achieved
$28M/year
Disposal Cost Eliminated
15 million bbl
Water Treated (Yr 1)
7.8M bbl/yr
Freshwater Offset
A major Marcellus operator wanted 100% water reuse across 6 active pads — eliminating produced-water hauling ($3.50–4.50/bbl) and freshwater trucking ($1.80/bbl) by treating flowback and produced water on-pad for reuse in the next frac job. Water TDS ranged 70,000–220,000 mg/L with high barium, strontium, and sulfates.
