Technology Overview

The use of produced water treatment technology is shifting toward employing integrated treatment trains over processing it in isolated steps since the generating companies need to comply with various water quality parameters. Indeed, the whole idea behind the commercial systems is enhancing the processing techniques, separating them according to the nature of the produced water to be treated, and thus meeting the water quality requirements for discharge, reinjection, recycling, or safe use of produced water.
Currently, there are several separation technologies being utilized at the stage where different separation techniques, flotation system, cyclone separators are utilized for extricating the oil and solid particles. Advanced processing systems employ filtration technologies that can reduce the number of hydrocarbons, suspended materials, impurities, and salts being removed. Thus, today, SLB has produced water solutions adapted to floating, cyclone separating, filtration, and other operations.

Produced Water Treatment Market Insights

Market Size & Growth

The produced water treatment market depends on the high amount of water produced by the world’s oil and gas production and the need to control, treat, recycle, or dispose of this water stream. The volume of produced water is dependent on various aspects of water reservoirs, the technology of production, the extent of the development of oil and gas fields, and location. According to USGS, produced water is one of the key water sources in connection with oil extraction. It also has a large database of geochemistry produced waters produced during extraction processes. The market trend has transitioned from just dealing with the produced water to more advanced treatment techniques such as recycling or reinjection of the water.

Key Application Areas

The demand for the treatment of produced water is high in both onshore and offshore oil and gas production, but the requirements differ based on the features of production, regulation, and existing disposal infrastructure. Onshore treatment demand heavily depends on the operations of large conventional and unconventional oil and gas producers. It demands treatment infrastructure where significant quantities of produced water need to be addressed through transportation, storage, disposal, and freshwater management.

Water-intensive hydraulic fracturing is used in unconventional production, which leads to repeated needs for treatment and recycling facilities as a large amount of produced water is generated following the drilling operation. USGS states that recently drilled wells in the Eagle Ford region have used around 13 million gallons water per well for hydraulic fracturing, generating approximately one million gallons or more of produced water.

Growth Drivers of the Produced Water Treatment Market

The growth of the oil and gas sector and the resultant rise in the volume of produced water has played a significant role in rising demand for produced water treatment. Produced water volumes are highly variable depending on the characteristics of the reservoir, the type of production involved, as well as the maturity of field operation, whereby the most mature or unconventional fields create the most significant requirements in terms of water management. The US Geological Survey classifies produced water as one of the major water streams related to oil production which creates ongoing need for treatment solutions and major infrastructure for their management. Other contributing factors include rise in significance of water recycling and reuse from both economic and regulatory standpoints. Increasingly, oil companies try to minimize their freshwater usage as well as costs related to transportation and disposal due to the growing focus on treatment of produced water which can then be reused for reinjection and hydraulic fracturing.

Key Market Trends & Challenges

There is a major change taking place within the produced water treatment sector, moving from alternative disposal methods to water management solutions based on recycling, reuse, and proper treatment. Key developments here include the growing use of advanced treatments, compact treatment systems, automated monitoring systems, and technologies aimed at cutting energy and chemicals costs. Moreover, operators actively seek treatment systems which can deal with the ever-complex produced water streams. Although separation technologies remain important for removal of large quantities of oil and solid particles, other methods such as advanced filtration, membrane techniques, thermal, chemical, electrochemical methods and so on are being assessed to provide higher-quality water. The increasing importance of water reuse means that providers are trying to make treatment systems which can meet the requirements for certain water quality in terms of end use rather than those of disposal. However, the issues of high treatment costs, unpredictable water chemistry, scaling and fouling, energy consumption and failure free performance at a commercial scale are still largely present.

Asia Pacific

The ongoing oil and gas production, a growing concern for water management, and investments in the upstream industry and supporting infrastructure in countries like China, India, Indonesia, Malaysia, and Australia continue to provide support for the produced water treatment market in the Asia Pacific region. It is noteworthy that offshore oil and gas production plays an important role in several markets and creates the need for compact, efficient, and reliable treatment systems that comply with the stated operational and discharge specifications. Other drivers are the growing pressure on operators in relation to water conservation, environmental management, produced-water recycling, and reduction of freshwater consumption. Furthermore, it is expected that investments in non-traditional and mature-field production in some countries will also fuel demand for produced-water treatment.
