Alterations in paraffin wax crystal networks induced by asphaltenes and pour point depressants, investigated by atomic force microscopy
Savulescu, George-Claudiu; Rücker, Maja; Simon, Sebastien Charles Roger; Øye, Gisle (Peer reviewed; Journal article, 2024)Wax crystallization in pipelines in cold environments is a key factor affecting flow assurance during crude oil production. Polar crude oil components, such as asphaltenes, and polymeric pour point depressants (PPDs) have ... -
Asphaltene fractionation based on adsorption onto calcium carbonate: Part 2. Self-association and aggregation properties
Subramanian, Sreedhar; Sørland, Geir Humborstad; Simon, Sebastien Charles Roger; Xu, Zhenghe; Sjöblom, Johan (Journal article; Peer reviewed, 2017)The self-association and aggregation properties of asphaltene sub-fractions obtained by adsorption onto CaCO3 (doi:http://dx.doi.org/10.1016/j.colsurfa.2016.02.011) were investigated using a combination of near infrared ... -
Improved Methods for Characterizing Emulsions by Low‑Resolution Nuclear Magnetic Resonance via Surface Relaxation and One‑Dimensional Images
Sørland, Geir; Less, Simone; Alkhabbaz, Sajjad; Simon, Sebastien Charles Roger (Peer reviewed; Journal article, 2023)The use of nuclear magnetic resonance (NMR) is an appropriate tool for studying colloids in a non-invasive manner. Droplet size distributions and one-dimensional sample profiles are readily produced to characterize an ... -

A theoretical and experimental investigation of batch oil-water gravity separation
Assar, Moein; Simon, Sebastien Charles Roger; Sørland, Geir; Grimes, Brian Arthur (Peer reviewed; Journal article, 2023)Gravity separation of oil-water emulsions is an industrially crucial process. Mechanistic models for a batch separation process can immensely be beneficial by linking emulsion experimental characterization to optimal ... -
Trends in food emulsion technology: Pickering, nano-, and double emulsions
Øye, Gisle; Simon, Sebastien Charles Roger; Rustad, Turid; Paso, Kristofer Gunnar (Peer reviewed; Journal article, 2023)Natural and industrial foods are often structured materials that impart texture, flavor, visual appearance, and nutritional value to the product, such as liquid–liquid emulsions stabilized by complex interfaces. This article ... -
Understanding the Effect of Asphaltenes and Wax Inhibitors on Wax Crystallization by Improved NMR Techniques
Savulescu, George-Claudiu; Øye, Gisle; Simon, Sebastien Charles Roger; Sørland, Geir (Journal article; Peer reviewed, 2023)Wax crystallization represents one of the main factors impacting flow assurance during oil production. Pour point depressants (PPDs) and asphaltenes present in crude oil have been linked to modifications in wax crystallization ...
