Asphaltene precipitation and its subsequent deposition is one of the major flow assurance
problems of oil industry. This issue could arise in upstream and downstream sectors. There …

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 …

Asphaltenes, as the heaviest and most polar fraction of petroleum, have been characterized
by various analytical techniques. A variety of fractionation methods have been carried out to …

With the projected increase in the production of heavy oil due to the energy crisis,
asphaltene-related issues are likely to come to the forefront. This leads to operational …

Precipitation and subsequent deposition of asphaltene in oil reservoirs may cause severe
flow assurance problems due to clogging/blocking of pore spaces and wettability alteration …

Asphaltenes are an important class of complex carbon-rich molecules found in crude oil.
Their chemical structure varies depending on the geological source but generally comprises …

A viscosity reducer was prepared by using octadecyl methacrylate (SA) and styrene (S) as
polymerization monomers and ethylene glycol dimethacrylate (EDMA) as branched …

Precipitation of asphaltenes in porous media undesirably influences oil recovery due to pore
clogging and subsequent wettability alteration. This study reports, primarily, the potential …

As an economic and efficient method, asphaltene dispersants are widely used to inhibit the
precipitation of asphaltenes in the crude oil tank. In this study, a series of multi-alkylated …

In this work, both experimental and theoretical procedures were performed to investigate the
effect of temperature, ranging from 25 to 65° C, on the performances of dodecyl benzene …
