Asphaltene is a component of crude oil that has been linked to serious production and
transportation issues. It is a solid oil component with various shapes and molecular …

Crude oils are complex mixtures of organic molecules, of which asphaltenes are the
heaviest component. Asphaltene precipitation and deposition have been recognized to be a …

The role of archipelago asphaltene structure in the reactions of petroleum asphaltenes was
investigated by comparing yields of products from the conversion of archipelago-rich heavy …

Deposition of asphaltene aggregates can easily depress the oil production, because it may
clog the wellbores, annulus, pipelines, and surface facilities. Moreover, asphaltene …

Carbon fibers are materials of paramount importance for composites applied in fields such
as aerospace engineering, medicine, and renewable energy. Currently, most of the …

In the past four decades, many experimental studies have confirmed the systematic events
occurring at the so-called optimum formulation of surfactant–oil–water systems. At this …

Gas hydrates constitute a major flow assurance issue in the transportation of oil and gas
from the reservoir to the point of sale via pipelines. They can reduce or arrest the …

In this research, six various asphaltenes extracted from crude oil mixtures of three Russian
refinery plants and some heavy residues of these plants were studied with applying …

The formation of highly stable water-in-oil emulsions results in complications in both
upstream and downstream processing. Emulsion stability in these systems has been …

In the production and transportation of crude oils, the interaction between asphaltene
components and water is inevitable, significantly impacting asphaltene aggregation …
