Suez announced it has been awarded by Petroleum Development Oman, a leading oil & gas company in the Sultanate, a design build own operate and maintain (DBOOM) contract for the treatment of 40,000 m3 each day of produced water coming from oil fields located in Rima, about 700 kms South of Muscat, Oman. This 20-year contract is worth €120 million in total revenues.

This contract aims at implementing alternative techniques to treat and dispose produced water, which is the oily wastewater generated during the extraction and recovery of oil. A large quantity of produced water is being generated from oil fields, depending on oil fields, one barrel of oil produces five to ten barrels of water. To ensure that this water is treated and disposed safely without harming the environment, Suez said it will implement an innovative treatment system to avoid deep well aquifers contamination, reduce energy consumption and enhance biodiversity.

Within this contract, Suez, main shareholder with 51 percent and its partners, Merit National Investments (LLC) and Al Shawamikh Oil Services (SAOG), with a 24.5 percent stake each, will be financing, constructing and operating for 20 years large wetland system and evaporation ponds over a surface of more than 400 hectares, using a technology designed by Wolf-Dieter Rausch, CTO of SusTeco (Sustainable Technology LLC).

A series of basins will be built over a period of 2 years, seeded with different species of algae. The produced water will be circulating through these basins and purified by biological actions which consist of biodegradation by microalgae and bacteria. The succession of varying wetland environments, with different flow speeds and depths of water develops these different mechanisms for pollutant absorption and will naturally treat the produced water. Once cleaned, the produced water will be disposed into 300 hectares ponds to be naturally evaporated beneath the Omani desert sun, as per the statement.

This natural and environmentally friendly treatment system will avoid the disposal of hydrocarbon-polluted produced water in the deep well aquifers. It will also significantly reduce the oilfield’s carbon footprint, and will generate 82 GWh savings in energy per year, compared to the conventional, energy-intensive disposal method of pumping the water into deep aquifers under high pressure.  

“We are very proud of this innovative project which strengthens our position in the Middle East in industrial market. This contract is in line with Suez’s strategy in the region to seize growth opportunities with industries and particularly in the energy sector. It is also reflecting the Group’s new value proposition to offer our customers a portfolio of high added-value solutions that are 100 percent sustainable with positive impact on environment, biodiversity and climate,” said Ana Giros, Senior Executive Vice President of Suez in charge of the APAC (Asia, Australia and India) and AMECA (Africa, Middle East, Central Asia) regions and industrial key accounts.
