Offshore biological treatment of oil & gas produced water

Activity: Talks and presentationsConference presentations


Produced water (PW) represents the largest volume waste stream generated in oil and gas production operations. PW has a complex composition, which includes various production chemical residuals and naturally occurring organic and inorganic chemicals that are frequently recalcitrant and difficult to remove.
Currently there is no treatment of PW offshore apart from the oil separation as physico-chemical and biological treatment methods utilized for treatment on land have various operational problems with safety and the footprint of most treatment systems are generally unacceptable large for an oil production platform. We present elements of the laboratory and pilot work towards designing a MBBR system that can operate on the seabed next to an oil platform in terms of treatment performance, variability in treatability between oilfields and the special possibilities and challenges connected with treating salty, 60 °C water at a depths that yields 3-6 bar pressure.
