Asphaltenes constitute the heaviest, most polar and aromatic fraction of petroleum crucial to the formation of highly-stable water-in-crude oil emulsions. The latter occur during crude oil production as well as spills and cause difficulties to efficient remediation practice. It is thought that in nanoaggregate form, asphaltenes create elastic layers around water droplets enhancing stability of the emulsion matrix. Ultrasonic characterisation is a high-resolution non-invasive tool in colloidal… 

Estimating the asphaltene critical nanoaggregation concentration region using ultrasonic measurements and Bayesian inference

Bayesian inference and ultrasonic velocity have been used to estimate the self-association concentration of the asphaltenes in toluene using a changepoint regression model and indicate that a lower abundance of the longer side-chains can cause an earlier onset of asphaltone self-Association.

Quantitative Modeling of Formation of Asphaltene Nanoaggregates

Association of asphaltene molecules to form aggregates is a defining property of this fraction of petroleum, which has impacts on all aspects of production and refining. Association has been detected

Adsorption kinetics of asphaltenes at the oil-water interface and nanoaggregation in the bulk.

This study elucidates aspects of asphaltenes effects based on new data on the interfacial tension in such systems from pendant drop experiments, supported by results from nuclear magnetic resonance (NMR) and dynamic light scattering (DLS) studies.

High-Q ultrasonic determination of the critical nanoaggregate concentration of asphaltenes and the critical micelle concentration of standard surfactants.

The results strongly support the contention that asphaltenes in toluene can be treated roughly within the micelle framework, although asphatenes may exhibit small levels of aggregation (dimers, etc.) below their CNAC.

Asphaltene Nanoaggregates Studied by Centrifugation

The colloidal structure of asphaltenes impacts various physical properties and is important to characterize. Previously, in both laboratory and oilfield studies, asphaltenes have been shown to form

Asphaltene Induced W/O Emusilon: False or True?

Tight brine‐in‐oil emulsions and related high viscosities are common oil field problems experienced in mid‐ to late‐life. Emulsions can have a detrimental effect on water separation efficiency, and

Advances in analytical chemistry, especially mass spectrometry, enable the identification of tens of thousands of distinct chemical species in crude oils and asphaltenes, which incorporates predictive petroleum science and provides a framework for future developments.

Water-in-Hydrocarbon Emulsions Stabilized by Asphaltenes at Low Concentrations.

The results imply that the emulsifying capacity of asphaltenes is reduced but not eliminated in better solvents.

Solution properties of asphaltenes.

The structure of asphaltene fraction solutions has been investigated using viscosity and X-ray scattering measurements as a function of concentration and a fractal model has been found to be consistent with dependence of all measured parameters.

Effects of Asphaltene Aggregation in Model Heptane-Toluene Mixtures on Stability of Water-in-Oil Emulsions

The results of this study strongly supports the theory that asphaltenes are the most effective in stabilizing emulsions when they are near the point of incipient precipitation and points to the significance of the solubility state of the asphaltones in determining the emulsifying potential of these crude oils.
