Asphaltene Deposition: Development and Application of Polymeric Asphaltene Dispersants
Proceedings of SPE Annual Technical Conference and Exhibition, 1991ABSTRACT Asphaltene deposition has a significant detrimental effect on oilfield production. The key to effective treatment of asphaltene deposition is recognition of the problem. Asphaltenes can be identified and quantified using laboratory methods.

Abstract Asphaltenes derived from both oil and source-rocks have been studied by pyrolysis-gas chromatography. The pyrograms obtained at 450 and 550°C show that asphaltene structure is very close to the structure of the kerogen of the same sample. They can be interpreted as kerogen moieties, resulting from its early evolution.

The luminescence of asphaltenes
Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 19701. The luminescence spectra of chloroform solutions of resins and asphaltenes, isolated from mazut, as well as components extracted from asphaltenes with petroleum ether, heptane, and benzene, were measured. 2. The luminescence of solutions of asphaltenes is due to the asphaltenes themselves, and not to resins that might have been ...

Interfacial behavior of asphaltenes
Advances in Colloid and Interface Science, 2016We review the existing literature on asphaltenes at various types of interfaces: oil-water, air-water, gas-oil and solid-liquid, with more emphasis on the oil-water interfaces. We address the role of asphaltene aggregation, recently clarified for asphaltenes in bulk by the Yen-Mullins model.

A Mesoscopic Model for an Asphaltene and Complex Mixtures of Asphaltenes
Petroleum Science and Technology, 2015A representation for an asphaltene system and asphaltene mixtures is proposed based on experimental data reported by Socrates et al. These were modeled at the mesoscopic level by applying dissipative particle dynamics (DPD), where DPD beads correspond to the main structure that constitutes the real asphaltene fraction.

Squalene in Petroleum Asphaltenes
Science, 1981Squalene, 2,6,10,15,19,23-hexamethyl-2,6,10,14,18,22-tetracosahexaene, a new biological marker, has been detected in various petroleum asphaltenes and their pyrolysis products. Since squalene is the most common triterpenoid in nature and the biological precursor of the important tetra- and pentacyclic triterpane markers, its detection in asphaltene ...

Effect of Asphaltene Concentration on the Aggregation and Precipitation Tendency of Asphaltenes
Energy & Fuels, 2014Destabilized asphaltenes can easily adhere to the oil well production equipment, the transportation pipelines, and also the refining and storage facilities, resulting in significant remediation costs. Therefore, it is of great importance to the energy industry to understand the factors that govern the kinetics of asphaltene aggregation and ...

Stability and Aggregation of Asphaltenes in Asphaltene−Resin−Solvent Mixtures
Energy & Fuels, 2004The Integral Equation Theory (IET) of fluids and molecular dynamics (MD) simulations have been used to study the stability and aggregation of asphaltenes in asphaltene−resin mixtures with different host solvents (n-heptane, toluene, and pyridine).
