Waters co-produced during petroleum extraction are normally considered wastes but are also possible resources, especially in water-stressed regions. Produced waters can be chemically complex. High salinity, naturally occurring radioactive materials, and organic substances derived from the producing formation can complicate treatment processes. Rapid screening methods to characterize produced waters could be important in determining effective and efficient treatment strategies, as the composition of these produced waters can vary dramatically. In this study, excitation-emission matrix spectroscopy (EEMs) was used to assess the types of fluorescent dissolved organic matter (fDOM) present in produced waters from six unconventional petroleum [...]

The purpose of this study was to 1) characterize the fDOM present in produced waters from a variety of petroleum systems, 2) compare fDOM concentration and composition within petroleum systems and across basins, and 3) evaluate the potential of EEMs as a tool in the development of produced water treatment processes.
