Partitioning of surfactants between the water and oil phases and relations to enhanced oil recovery methods
Teigen, Erlend (Master thesis, 2014)The focus in this master thesis has been to investigate how a varying Ca2+/Na+ mole fraction affects the interfacial tension of a surfactant/brine - dodecane/toluene interface. It has also been investigated how the same ... -
Potential applications of magnetic nanoparticles within separation in the petroleum industry
Rodionova, Galina; Strand, Mikael; Øye, Gisle (Journal article; Peer reviewed, 2018)Magnetic nanoparticles have unique properties such as extremely large surface area per volume substance and strong magnetic response. In addition, the possibilities for surface functionalization make them exciting candidates ... -
Produced Water Quality and Microfluidic Methods for Studying Drop-Drop and Drop-Bubble Interactions in Produced Water
Dudek, Marcin Jan (Doctoral theses at NTNU;2018:198, Doctoral thesis, 2018)Produced water originates from crude oil production, during which it is extracted to the surface together with hydrocarbons. It consists of various dissolved and dispersed components, such as dissolved organic and inorganic ... -
Recent advances in the design and use of Pickering emulsions for wastewater treatment applications
Gricius, Zygimantas; Øye, Gisle (Journal article, 2023)Pickering emulsions have recently emerged as versatile systems capable of targeting many applications of wastewater treatment. The unique properties, which include high emulsion stability, easy preparation, low toxicity, ... -
Removal of dispersed oil drops by induced gas flotation
Panneer Selvam, Arun Kumar (Master thesis, 2018)Produced water is an important byproduct of oil and gas production. With increasing number of maturing reservoirs, global oil to water cut is in the ratio of 1:3. Treatment of produced water is essential due to its detrimental ... -
Reservoir-on-a-chip: Two-phase flow in porous media studied by advanced microfluidic methods
Vikse, Nora Birgitte (Master thesis, 2020)Råolje er den viktigste energikilden i verden. Med en økende etterspørsel etter energi har det blitt viktig å forbedre oljeutvinningen. Flere metoder brukes for å produsere råolje. Imidlertid forblir en stor mengde råolje ... -
Separation-on-a-chip: coalescence and the influence of demulsifiers in w/o emulsions studied by advanced microfluidic methods
Edøy, Karoline Øverlie (Master thesis, 2020)Petroleumsindustrien produserer betydelig store mengder vann ved produksjon av olje, og dermed vil oljeemulsjoner være tilstede i reservoarene. Siden emulsjoner er termodynamisk ustabile, kreves det energitilførsel for å ... -
Studying droplet retention in porous media by novel microfluidic methods
Azizov, Ilgar; Dudek, Marcin; Øye, Gisle (Peer reviewed; Journal article, 2022)Transport of oil droplets through porous media is an important topic in the oil and gas industry. Oil droplets that are present in produced water contribute to injectivity decline during re-injection due to retention in ... -
The effect of calcium/sodium ratio on the dynamic adsorption of sodium dodecyl benzene sulfonate (SDBS) onto water/air interfaces. Evaluation of critical micelle concentrations, diffusion coefficients and molecular areas
Olsen, Arnt Ove Jektvik (Master thesis, 2016)Test how calcium/sodium-ratio affect the dynamic adsorption of sodium dodecyl benzene sulfonate (SDBS) onto water/air interfaces where the ionic strength is kept constant at 20 mM, with the use of maximum bubble pressure ... -
The effect of dissolved gas on coalescence of oil drops studied with microfluidics
Dudek, Marcin; Muijlwijk, Kelly; Schroën, Karin; Øye, Gisle (Journal article; Peer reviewed, 2018)Hypothesis In literature it is stated that the stability of oil-in-water emulsions could be enhanced by decreasing the so-called “hydrophobic interactions” between surfaces through removal of dissolved atmospheric gases. ... -
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 ... -
