We understand water is a critical part of the production process for the upstream oil and gas industries, which use and produce high quantities of water for everything from exploration to production. http://www.degremont.com.au/

2. Degrémont Industry — WATER FOR the UPSTREAM OIL & GAS industry
Degrémont Industry 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.
Degrémont Industry 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
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.
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.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.

Understanding your specific challenges
Conventional Oil and Gas Industries
(Heavy Oil, Light Oil)
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 beneficial reuse.
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 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,...).
