# Floating covers for oil and gas produced water

Cut VOC release, evaporation, and odor on produced-water ponds and oilfield reservoirs. EU Industrial Emissions Directive ready.

Hexagonal floating covers reduce VOC and BTEX release on produced water ponds by 85–95% and
evaporation on oilfield water storage by 90%+.

## What covers do for oil and gas operators

Produced water management is a regulatory and operational pressure point. Hexagonal floating
covers reduce VOC and BTEX release at the water surface, eliminate evaporation losses in arid
oilfield regions, and support compliance under the EU Industrial Emissions Directive.

## Benefits

| Application | Benefit |
|---|---|
| Produced water ponds | VOC + BTEX release reduction |
| Oilfield water storage | Evaporation reduction |
| Wastewater treatment | Odor + H₂S reduction |
| Heat retention on hot water | Process energy retention |

## How covers work for produced water and oilfield storage

A floating cover on a produced water pond removes the water-air interface that drives BTEX, VOC,
and (where present) H₂S release. The patented self-ballasting hexagonal geometry tolerates the
chemical conditions typical in produced water; site-specific compatibility assessment is needed
for exotic chemistries (high-acid produced water, certain corrosion inhibitor packages).

## When to use covers in oil and gas

- Produced water storage ponds (VOC + BTEX reduction)
- Oilfield water make-up storage in arid producing regions
- Frac water storage where evaporation losses are material
- Workover fluid management ponds (odor + safety)

Covers are NOT appropriate for surface impoundments holding hydrocarbon-containing fluids where
material compatibility hasn't been verified; consult chemical compatibility tables before specifying.

## Covers vs. alternative VOC controls

- Floating covers reduce VOC release at the water-air interface by 70-85%.
- Closed-tank conversion (replacing the open pond with a covered tank) achieves higher capture
  but at substantially higher capex.
- Surface foam blankets are short-lived and require continuous replenishment.

For most produced-water surface management, modular hexagonal covers are the most cost-effective
intervention; closed-tank conversion is the appropriate escalation for sites where regulator
requires near-zero release.

## Regulatory context

EU IED, OSPAR (for offshore-adjacent operations), and national permitting all increasingly demand
documented VOC emission reduction at industrial water surfaces.
