Molecular Dynamics Study on Aggregating Behavior of Asphaltene and Resin in Emulsified Heavy Oil Droplets with Sodium Dodecyl Sulfate

Energy & Fuels, 2018
The aggregates of asphaltene and resin molecules play an important role in stabilizing heavy crude oil. Although many experiments are applied to investigate the complex aggregating structure of asphaltene and resin molecules in heavy crude oil, those ...

Molecular Mechanisms of Suppressing Asphaltene Aggregation and Flocculation by Dodecylbenzenesulfonic Acid Probed by Molecular Dynamics Simulations

Energy & Fuels, 2019
The behaviors of an asphaltene model compound, N-(1-undecyldodecyl)-N′-(5-carboxylicpentyl)-perylene-3,4,9,10-tetracarboxylbisimide (C5PeC11), in the absence and presence of an asphaltene inhibitor...

Microfluidic Study of the Deposition Dynamics of Asphaltene Subfractions Enriched with Island and Archipelago Motifs

Energy & Fuels, 2019
Asphaltene-related flow assurance problems are prevalent in oil production processes and are at the heart of issues such as the plugging of pipelines, the damage of rock formations, and the stabilization of viscous water-in-oil emulsions. A comprehensive

Experimental investigation of effect of asphaltene deposition on oil relative permeability, rock wettability alteration, and recovery in WAG process

Petroleum science and technology, 2019
Asphaltene deposition is considered to be one of the most problems during oil productions. This work describes the effect of asphaltene precipitation and deposition on relative permeability of reservoir rock during water alternating gas (WAG) injection ...

Asphaltene Deposition

Canadian International Petroleum Conference, 2000
Introduction Production of heavy oils and paraffinic crude reserves often results in the deposition of organic solids, typically waxes or asphaltenes. The organic deposits can reduce the productivity of the reservoir as well as foul piping and surface equipment.

ADSORPTION OF ASPHALTENE FUNTIONALITIES AND ASPHALTENE ON GOETHTTE

Fuel Science and Technology International, 1995
ABSTRACT Solid-stabilized water-in-oil emulsions cause many problems such as oil loss, fouling of a processing unit, and environmental hazard in the petroleum production and refining. The ability of finely divided solids to stabilize these emulsions is due to the adsorption of asphaltenes and other heavy constituents. This study presents the individual

Interfacial behavior of asphaltenes

Advances in Colloid and Interface Science, 2016
We 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.

Systematic Investigation of Asphaltene Deposition in the Wellbore and Near-Wellbore Region of a Deepwater Oil Reservoir Under Gas Injection. Part 1: Thermodynamic Modeling of the Phase Behavior of Polydisperse Asphaltenes

Energy & Fuels, 2019
Thermodynamic modeling is conducted for a high-asphaltene, high-resin crude oil produced from a deepwater reservoir using the perturbed-chain statistical associating fluid theory (PC-SAFT).

Squalene in Petroleum Asphaltenes

Science, 1981
Squalene, 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 ...

Electrokinetic Characterization of Asphaltenes and the Asphaltenes−Resins Interaction

Energy & Fuels, 2003
The electrophoretic mobility of asphaltene particles formed by precipitation induced by the addition of n-heptane to asphaltene solutions in toluene was measured in water and in nonpolar media. Dispersed in water, the particles presented a negative electrophoretic mobility, whereas in toluene their mobility was positive and around 2.0 × 10-9 m2/V s ...
