Oil Industry – Upstream

Veolia Water Technologies provides state-of-the-art technology and advice tailoured to oil and gas customers. The upstream needs for development and production require innovative installations that comply with environmental standards. Veolia Water Technologies also delivers quality water and technologies that ensure its optimal reuse.

Our commitment to reduce water needs

Veolia Water Technologies is the world leader in water treatment. We have more than one hundred years of experience in the field. For several decades, we have offered companies in the oil and gas sectors a wide range of technologies and industrial processes. We are particularly renowned for solutions related to the upstream activities of the oil industry.

Across the globe, the 9,000 employees making up Veolia Water Technologies teams are tasked with:

  • sustainable development ideas
  • helping our partners achieve their goals
  • constantly innovating in circular economy technologies 
  • respecting environmental rules 

Water is an essential element for extracting and refining hydrocarbons, and quality water is useful throughout the various processes of these actions – whether for prospecting, enhanced oil recovery or enhanced chemical recovery. Our water expertise is highly regarded, and we’re a preferred partner of the sector. Our water technologies guarantee our customers a competitive advantage by reducing their water needs while ensuring compliance with regulations.

MPPE® technology to preserve natural environments

Veolia Water Technologies removes traces of hydrocarbons from water with MPPE® water treatment technology. This inexpensive process requires few additional chemicals. The MPPE® system makes it easy to comply with all regulations regarding the release of pollutants into the natural environment. This technology has a removal rate of over 99.9%.

Meeting the needs of upstream petroleum activities

Many onshore producers trust the field expertise of Veolia Water Technologies. We take full responsibility for wastewater treatment and sludge management. These areas are particularly important in the context of petroleum activities, whether that’s during the refining process or in petrochemical processing activities. Many onshore producers trust Veolia Water Technologies as a result of our extensive experience in the field.

Our main client activities provide support in the following areas:

  • Better recovery of crude oil.
  • Treatment of injection water.
  • Water treatment for reuse.
  • Effluent treatment.
  • Water treatment during the refining process.

Zero liquid discharge for Shell's Pearl GTL installation

Our partnership with Shell and Qatar Petroleum in the Pearl GTL site enabled the installation of advanced technologies to reduce its environmental impact – with our zero liquid discharge (ZLD) technology completely manages effluent and process water in a closed circuit. Effluents and process water are fully managed in a closed circuit. The wastewater treatment capacity reaches 45,000 m3 per day

Injection and oil recovery

Our processing solutions are as well suited to conventional oil and gas production methods as there are to enhancing chemical oil recovery and hydraulic fracturing. This enables us to provide complete solutions for improving the productivity rates of installations, while ensuring the safety of equipment by eliminating elements that could obstruct the tanks or the equipment injections.
Since water injection is essential for exploiting oil and gas deposits, we offer our customers injection water produced from seawater, wastewater, brackish water, etc.


The benefits of water reuse

The reuse of water produced for recycling is an inexhaustible source of cost savings for hydrocarbon producers. This Circular economy processes include:

  • process water
  • injection water for onshore applications
  • injection water for offshore applications
  • the distillate used for evaporation purposes

Offshore activity contributions

The injection of quality water is essential to maintain reservoir pressure without causing damage. Seawater naturally contains sulfates which must be removed to ensure optimum equipment life. Veolia Waters Technologies, the world leader in desalination technologies, offers turnkey treatment systems.

Filtration pretreatments use reverse osmosis and membrane nanofiltration processes.Our modules are simple to install and meet all specifications of offshore installations.
