What is produced water?
The worldwide decline in conventional Oil & Gas reserves is focusing the energy sector towards the development of unconventional reserves. However, unconventional oil and gas production requires large quantities of water. This “produced water” has highly challenging physical and chemical properties, which can vary significantly throughout the production lifespan. Evolving regulations and fresh-water scarcity are pushing the industry to treat and re-use this produced water, which means the establishment of reliable, sustainable and cost-effective produced water treatment solutions is fundamental for achieving successful, long-lasting operations.

Wintershall, Germany: over 20 years of produced water treatment, operating at 98% availability
Produced Water Treatment
The continuous, reliable and robust supply of water is essential to maximize production in non-conventional oil and gas extraction. The challenges of this industry are significant: security, remote location, extreme temperatures and climates, and high operating costs due to difficult logistics, among other factors.
IDE’s solutions are based on our 20-year experience. We provide high reliability solutions that reduce Capex and Opex due to the flexibility and adaptability of our modular approach.
For steam-based treatments, IDE’s solutions provide high-quality distillate for maximum steam production, allowing greater efficiency of more oil production.
For non-vapor-based treatments, such as shale or bituminous gas, IDE’s solutions reuse water to deliver greater recovery with less replenishment water, hence savings costs.
Steam Assisted Gravity Drainage (SAGD)
Previously inaccessible sources of oil and shale gas are becoming accessible due to the advance of technology. SAGD is a technology that is changing the industry, but needs a growing and continuous supply of high quality steam.
Robust and reliable evaporators, with capacity to handle the chemical composition of water, scale conditions, fouling, silica precipitation and the remote environment of Alberta’s bituminous sands in Canada, are critical to SAGD.
Using its market-leading expertise and experience, IDE can meet the specific needs of the SAGD industry, with cost-effective solutions that are resistant to extreme climatic conditions, energy efficient and easy to transport, build and deploy. In such remote conditions, we understand the need for easy maintenance, high security, easy recovery from precarious conditions and lower installation costs. IDE’s solutions are closed-loop, so that there is less replacement due to high recovery.
Modular. Horizontal. Unique.
Due to its special horizontal design, IDE’s industrial mechanical Steam Compression Unit can be modularized, with a fully operational system within a standard size module (24′ x 24′ x 120′). This makes it easier and faster to transport and assemble it, and reduces and limits the uncertainty in the project delivery schedule.
Quick assembly: The modularization, testing and complete assembly of the systems takes place off-site. The units are delivered fully assembled and ready for installation on the equipment foundations, allowing to start working earlier.
Easy transport: Due to its standard modular size, IDE’s complete solution can be easily delivered.
Very cost-effective: Its unique design creates substantial cost savings by minimizing the high cost of on-site installation under difficult working conditions. The units are installed and put into operation sooner than with the traditional methods, thus allowing a faster return on investment.
Lower costs, faster installation
IDE’s industrial mechanical vapor compression units are specially designed for the market of Alberta’s sands, to minimize:
- Labour costs and on-site installation materials.
- Loads applied to the foundations.
- Building requirements.
In real terms, this means that upon arrival on the site:
- IDE units are positioned and anchored to the foundations in two or three days.
- The interconnection of the feed water, brine and the coiled tubing modules of the distillate are installed in two weeks.
- The electrical, instrumentation and control connections are installed in two weeks.
- The start-up and commissioning are completed in two weeks.
Coal Seam Gas
Water, a by-product of the coal seam gas industry, often has a difficult chemistry, such as scaling and precipitated silica. Given the isolated locations, extreme conditions, environmental regulations, and safety and health concerns, it is critical to treat this water effectively, efficiently, and reliably.
IDE provides efficient and mobile solutions for the Coal Seam Gas industry that reduce Capex and Opex. These solutions are based on our 20-year experience, and are flexible and adaptable to a wide variety of environments and situations. The reliability of our units provide highly cost-effective water treatment solutions.

Utilizing Available Coldness from Liquefied Natural Gas LNG Regasification Process for Seawater Desalination
In this article a case study was considered, in which an LNG regasification plant can supply 1750 ton/hr of water-glycol solution at -15°C to be utilized for seawater desalination. The main challenge in this evaluation is being able to provide a desalination solution able to compete with the commonly used RO plants.
