Abstract

This thesis documents the use of benchtop Nuclear Magnetic Resonance (NMR) in the characterisation of various oil-water mixtures. The predominant focus of this work investigates the role of mixture composition in affecting the stability of water-in-crude oil emulsions. This is achieved through characterising the role of aqueous phase pH, the effect of naphthenic acid origin, and the effect of a subset of asphaltenes on emulsion stability. Additionally, the utility of NMR in quantifying water – monoethylene glycol mixtures and in assessing the stability of processed Pickering emulsions is successfully demonstrated.
