Microfluidic Study on the Attachment of Crude Oil Droplets to Gas Bubbles
(Journal article; Peer reviewed, 2018)Gas flotation is often used during treatment of the oilfield produced water. It relies on the generation of gas bubbles and their attachment to oil drops, for example, by forming an oil film on the surface of a gas bubble. ... -
New Nuclear Magnetic Resonance Approaches on the Evolution of Wax Mobility during Wax Crystallization
(Peer reviewed; Journal article, 2021)Wax crystallization at low temperature is one of the main problems affecting flow assurance during oil production. Wax inhibitors, such as pour point depressants (PPDs), and crude oil components, such as asphaltenes, are ... -
Novel Nuclear Magnetic Resonance Techniques To Assess the Wax Precipitation Evolution in Crude Oil Systems
(Peer reviewed; Journal article, 2022)Wax crystallization in cold environments constitutes one of the main causes for flow assurance problems during oil production. Several techniques, such as differential scanning calorimetry (DSC) or gas chromatography/mass ... -
Screening of Inhibition of Calcium Naphthenate Deposition in Crude Oil
(Peer reviewed; Journal article, 2021)One of the initial steps in calcium naphthenate deposition is the reaction between ARN and Ca2+ leading to the formation of an interfacial gel. After growing, this gel will form calcium naphthenate deposits that are a ... -
Solubility and Heat of Absorption of CO2 into Diisopropylamine and N,N-Diethylethanolamine Mixed with Organic Solvents
(Journal article; Peer reviewed, 2020)We have evaluated the vapor–liquid equilibrium and heat of absorption of CO2 over water-lean mixtures of the amines diisopropylamine and N,N-diethylethanolamine (DEEA). This extends our previous research on water-lean ... -
Some Compositional Viscosity Correlations for Crude Oils from Russia and Norway
(Journal article; Peer reviewed, 2016)The current work is based on experimental viscosity and compositional data of about 200 crude oil samples from various parts of Russia and the Norwegian continental shelf. Data analyses were performed to estimate correlations ... -
Wax-Inhibitor Interactions Studied by Isothermal Titration Calorimetry and Effect of Wax Inhibitor on Wax Crystallization
(Journal article; Peer reviewed, 2017)Isothermal titration calorimetry is applied to investigate the interactions of polymeric pour-point depressants (PPDs) or asphaltenes with macrocrystalline wax in a model oil system. This represents a novel approach to ...
