Microfluidic testing of flocculants for produced water treatment: Comparison with other methodologies
Dudek, Marcin; Ullaland, Hanne Skudal; Wehrle, Amandine; Øye, Gisle (Peer reviewed; Journal article, 2020)Flocculants are often added during produced water treatment to improve the crude oil droplet growth and separation from the water phase. Prior to use in the field, their performance is tested in laboratory conditions, ... -
Microfluidic tools for studying coalescence of crude oil droplets in produced water
Dudek, Marcin; Bertheussen, Are; Dumaire, Thomas; Øye, Gisle (Journal article; Peer reviewed, 2018)The major contaminant targeted during the treatment of the oilfield produced water is dispersed oil. The efficiency of most separation processes highly relies on the size of the droplets, which can be increased through ... -
Optimal operation of a subsea separation system including a coalescence based gravity separator model and a produced water treatment section
Das, Tamal; Heggheim, Sindre Johan; Dudek, Marcin; Verheyleweghen, Adriaen; Jäschke, Johannes (Journal article; Peer reviewed, 2019)In this work, we develop a model for a gravity separator, and we use it together with models from the literature to study the control of a subsea separation system that separates oil, gas, and water from well fluids in ... -
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 ... -
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 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. ... -
Wettability effect on oil recovery using rock-structured microfluidics
Yang, Junyi; Saadat, Marzieh; Azizov, Ilgar; Dudek, Marcin; Øye, Gisle; Tsai, Peichun Amy (Peer reviewed; Journal article, 2022)Surface wettability has a crucial impact on drop splashing, emulsion dynamics, slip flow for drag reduction, fluid–fluid displacement, and various microfluidic applications. Targeting enhanced oil recovery (EOR) applications, ...
