Produced water is a term in the oil and gas industry that refers to any water discharged from an oil or gas reservoir as part of the production process. The produced water contains contaminants and needs to remove before proper disposal or reuse. Some impurities or substances present in the produced water include oil, naturally occurring radioactive materials (NORM), wax, grease, sand, scale, dissolved salts, carbon dioxide, and hydrogen sulfide gas, other hydrocarbons, production chemicals, and various metals.
The global produced water treatment market expected to increase market value by USD 17.8 billion, increasing CAGR in the forecast period from 2020-2027. The market demand for produced water treatment is increasing due to the growing oil and gas industry’s exploration rate of offshore and onshore reserves. The emerging need for water treatment owing to the water act and bolstering technology such as physical separation and membrane technology are others driving the market share.
Produced water has a series of characteristics such as large water volume, sophisticated water quality, and great difficulty in treatment. Therefore, the search for suitable treatment technology has always been the main problem faced by oil fields.
The extraction of heavy oil usually involves the production of steam injected into the formation (steam flooding, circulating vapor, SAGD). To minimize or eliminate the consumption of freshwater supply steam in the generator, the produced water often treated and adjusted to the water quality suitable for the supply of steam generators.
Moreover, the stringent rules and regulation of government regarding the environmental impact of produced water disposal and scarcity of potable water are rising the need for water cleaning treatment.
The shortage of potable water is rising the concern for the adoption of produced water treatment. The oil field water recovery and reuse services are becoming more and more common. The main reasons include increased oil field production, increased reinjection underground sensitivity, and increased fracturing water demand. Oilfield water treatment often utilizes several technologies, including gas flotation units for solids separation and walnut-shell filters for dispersed-oil removal. Moreover, the government taking measures and doing acts for treating the produced water in oil fields and utilize the water for different purposes.
Reinjection was adopted very early as a measure to prevent water pollution. The treatment technology of produced water reinjection is mostly oil removal, coagulation and sedimentation, air floatation, and filtration. The specific details and design parameters determined according to the actual conditions of each gas field. In the reinjection treatment process, contaminants such as dissolved organic matter, heavy metals, and salt content are not removed. As the ecological environment becomes increasingly fragile, environmental protection requirements are gradually improved. This simple treatment method obviously cannot solve the fundamental problem, and a better solution must find.
Based on the source, the global produced water treatment market segment into Crude Oil, Natural Gas. The natural gas segment estimated to dominate the maximum share of the global produced water treatment market. It is mainly owing to the technology advancement, and the rising demand for LNG is driving demand for the global produced water treatment market. As liquified natural gas is the cleanest burning fossil fuel and the emerging use of natural gas has significantly enhanced the local air quality and public health safety as well as reduce carbon dioxide (CO2) emissions.
Based on service, the global produced water treatment market classified into Primary separation, Secondary separation, Tertiary separation, and others. The secondary separation method segment dominated the largest market share in the global produced water treatment market. An oilfield secondary produced water treatment method, which relates to a sewage treatment process, particularly in an oilfield secondary produced water treatment process. The secondary separation technique is driving the market owing to the reduction the greenhouse gas emissions and emerging environmental concerns related to the oil & gas industry, which produces harmful substances such as benzene, toluene, and xylene. Moreover, secondary treatment based on techniques such as adsorption, biodegradation, stripping, and membrane separation, which help remove organic compounds, suspended solids and oil, and eliminate the dissolved aromatic hydrocarbons BTEX and NPD.
Based on the application, the global produced water treatment market bifurcated into Onshore, Offshore. The onshore segment is capturing the maximum share in the global produced water treatment market. The onshore section requires produced water treatment to reduce the utilization of water for irrigation purposes. Moreover, the offshore segment expected to expand in the forecast period from 2020-2027. It is mainly due to the oil and gas industry’s adoption of advanced technology and secondary treatment to reduce the spilling of oil in the offshore sector.
Based on geography, the global produced water treatment market segmented into North America, Europe, Asia Pacific, South America, and Middle East & Africa. North America is the world’s fastest-growing global produced water treatment market, accounting for the largest share. It is mainly due to the growing development of shale gas, and in the process of gas production, gas wells will produce a lot of produced water. The need for adoption of produced water treatment is required to reduce the large sewage discharge. Therefore, North America is bolstering the market demand in the produced water treatment market.
Companies such as Aker Solutions, ThermoEnergy Corporation, Alderley plc, Frames Group, CETCO Energy Services, Schlumberger, Global Water Engineering, Siemens AG, Ecosphere Technologies, Inc., FMC Technologies, Veolia and others are key players in the global produced water treatment market.
