Water treatment for Upstream Oil and Gas industry

Water is a critical part of the Production process of Upstream Oil & Gas industries which use and produce high quantities of water from Exploration to Production:

• External source of water for injection
  Depending on the water resource available (seawater, brackish water, freshwater), water treatment solutions differ in order to produce Injection Water.
• Produced Water / Waste water
  Generated by the Exploration & Production activity, the Produced Water needs to be treated before reuse or discharge to the environment.
• Reuse / Produced Water reinjection
  The recycling of the Produced Water limits the external water source consumption.

Therefore, water is a key part of Exploration and Production processes and the correct water quality is essential for EOR (Enhanced Oil Recovery).

To achieve their performance objectives, several challenges need to be assessed:

• Integration of water technologies in order to meet environmental and local constraints (space, discharge and water resources availability)
• Cost optimisation
• Environmental footprint management and reduction: major changes to environmental regulation

Furthermore, robust and reliable solutions are required to ensure the installation longevity, since the well lifetime spans around 25 – 30 years.

Degrémont Industry provides a complete portfolio of proven sustainable solutions to produce Injection Water, treat and reuse Produced Water in order to optimise water management according to local requirements and minimise production risks.

Degrémont Industry expertise in water treatment applies to all the following sectors:

• Offshore Oil & Gas: Conventional & Unconventional
• Onshore Oil & Gas: Conventional & Unconventional
