| Abstract: | "Produced water (water co-produced with oil and gas) constitutes the single largest waste stream for oil and gas industry. Reclaiming this water for beneficial use is thought to be one of the most practical solutions that can solve both environmental and water shortage problems. The feasibility of this practice depends on the ability to remove its chemical content to the levels that meets the appropriate standards. Organic compounds are probably the most difficult fraction to handle. In this paper, the discrete organic compounds and non-volatile, macromolecular organic compounds (i.e., natural organic matter--NOM) of three produced water samples from the Osage-Skiatook Environmental Research site were characterized. Two of the three produced waters had very little contribution from NOM, while one of the samples had about 23% NOM contribution to its organic matrix pool. Fluorescent spectrophotometric scans provided little differentiation among the organic quality of the produced water, while pyrolysis-GC/MS showed that the NOM characteristics of the three produced waters were distinct. Specifically, the overall halogenated content and aromaticity of the NOM were found to be possible qualifiers that distinguish produced water from the coalbed methane well from produced water from the oil well. And the specific chemical fragments that are linked to polysaccharide sources were found to be potential identifiers that distinguish produced water from the newer oil well from produced water from the older oil well. These identifiers were, however, only suggested for this preliminary study. More samples must be included to build a substantial database on produced water NOM to confirm and identify more markers" |
