ENVIROUNIT Offshore Slop Water Treatment System

Compact, portable systems for treating drilling wastes offshore.

Oil Removal

Produced water treatment systems that enable reuse, discharge, or water disposal.

Enabling reuse, discharge, or disposal of produced water

The US alone generates billions of barrels of produced water annually, making this water the oil and gas industry’s most abundant by-product. Before it can be used for enhanced oil recovery (EOR), placed in a disposal well, or discharged offshore, produced water's entrained oil and suspended solids content must be reduced to a level that meets HSE regulations, protects formation rheology, and limits equipment corrosion.

Worker at seawater treatment facility

Rendering seawater suitable for use in hydrocarbon production

Oil and gas facilities use seawater for a variety of applications, including EOR, equipment cooling, fire suppression, potable water generation, and desalter operations. Prior to its use, seawater must be suitably treated for biofoulants, dissolved oxygen, and suspended or dissolved solids.
