dc.description.abstractWater in one form or another is present within countless manufacturing processes. In an oil extraction process, the volume of water is typically equal to the produced hydrocarbons and can even exceed the amount of extracted oil significantly. The large volumes of water, known as produced water, inflict problems. These problems are mainly related to dissolved ions that produced water is carrying. In oil production and several other industries, where pipelines are used to transport water, in suitable conditions, ions within the water will precipitate and form scale. Within a pipeline, scale may accumulate and disturb the liquid flow through the pipeline. In order to assess the scale potential, this thesis develops a fluorescence based analytical method for identifying components that can induce scale within produced water. In this thesis, the studied water samples are called produced water, which is an oil extraction by-product. This thesis examines the technique of time-resolved photoluminescence to develop a non-specific assay method for identifying several ions that may cause scale accumulation in production pipelines. The developed method was used to analyse both synthetic and field produced water samples. The results of this thesis indicate that thorough study of suitable assay components enables the possibility to create a measurement protocol to evaluate ion concentrations in a produced water sample. The quantification of ion concentrations allows the evaluation of scale potential in a production pipeline. This evaluation can be used to assess the need for treating chemical to prevent scale accumulation within the pipelines.en
