InjectIon water and produced water to Improve oIl & gas recovery

Water is critical to Oil & Gas Exploration and Production. Whether it is 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 as well as those related to local regulations and environmental constraints.

Cost optimisation of water treatment lines remains a fundamental concern and requires innovative or tailor-made solutions which meet the complex conditions and needs of Upstream Oil & Gas industrials. Indeed, Degrémont Industry supplies robust and reliable water treatment systems and services to ensure the long lasting service life of a facility.

External water sources for injection

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 – i.e. particles (5-2-1µ) and salinity adjustment.

Moreover this injection water quality (e.g. 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.

Water Reuse or Discharge

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.

Produced water and reinjection for EOR and chemical EOR

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.

Unconventional Oil and Gas Industries (Extra Heavy Oil, Oil Sands, Shale Oil & Gas, Tight Oil & Gas, Ultra deep reservoirs, Pre-salt reservoirs, Coal Seam Gas, Coal Bed Methane)

For Oil Sands and Heavy Oil, raw water or produced water is treated for steam generation and injection to mobilize the 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 which is extracted alongside Coal Bed Methane needs to be treated (metals, etc.) for deep reinjection or benefi-cial reuse.

Understanding your specific challenges

Conventional Oil and Gas Industries (Heavy Oil, Light Oil)

The water quality must meet reservoir requirements. The adequate quality of produced water contributes to Enhanced Oil & 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 particles adjustments (i.e. 5-2-1µ) before reinjection.

Mature Oil fieldsMature 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,...).
