SUEZwater for the upstream oil & gas industry


injection water and produced water to improve oil & gas recovery

SUEZ understands water is critical to oil & gas exploration and production. Whether for Enhanced Oil Recovery (EOR) or chemical EOR, for reuse or discharge, water quality is crucial. Water treatment process lines have to meet requirements related to reservoirs, local regulations and environmental constraints.

Cost optimisation of water treatment lines remains a fundamental concern and requires innovative solutions which meet the complex conditions and requirements of the upstream Oil & Gas Industry.

SUEZ is committed to combating these challenges by providing smarter water solutions that are reliable, cost effective and tailored to meet our clients’ needs.

water reuse or discharge external water sources for injection

produced water and reinjection for EOR and chemical EOR

Increasingly stringent environmental regulations encourage the Upstream Oil & Gas Industry to reduce its environmental footprint and develop efficient water treatment solutions for reuse or discharge.

The amount of produced water and its contaminants (TDS, TSS, dissolved and volatile organic compounds (VOCs), heavy metals, and chemicals used in production such as biocides, lime and corrosion inhibitors, etc.) usually vary over the field’s lifetime.

To produce injection water or steam, different kinds of external water resources are available: seawater, brackish water, well water, lake water, river water or municipal wastewater.

For injection and/or Enhanced Oil Recovery purposes, water treatment process lines differ depending on the external water resource available and on the water quality required by reservoirs – ie. particles (5-2-1µ) and salinity adjustment.

Moreover this injection water quality (eg. filters, deoxygenation processes, sulphate removal) must not cause corrosion or indirect decreased oil production.

For shale oil and gas, water is essential for extraction processes.

The amount of produced water may rise as the field matures. Produced water treatment for reinjection purposes is key to Enhanced Oil Recovery and chemical EOR.


The water quality must meet reservoir requirements. The adequate quality of produced water contributes to enhanced oil and gas recovery. In gas fields, the produced water contains SS (Suspended Solids), oil, BTEX and MEG.

Oil fields (non mature)

Oil and TSS removal enables particle adjustments (i.e. 5-2-1µ) before reinjection.

Mature oil fields

Mature oil fields require chemical EOR for the extraction of the remaining oil. The produced water quality must also be adjusted to the chemical requirements (A, S, P, ...).

For oil sands and heavy oil, raw water or produced water is treated for steam generation and injection to mobilize bitumen or heavy oil.

For shale oil & gas and coal seam gas, mobile water treatment solutions are most suitable during the exploration phase (flowback water) followed by semi mobile/fixed units during production phase (produced water).

Coal mine water extracted alongside coal bed methane needs to be treated (metals, etc.) for deep reinjection or beneficial reuse.
