Asphaltene adsorption on reservoir rock minerals causes wettability alteration and pore
plugging which subsequently reduces crude oil production. Also, it has a negative effect on …

The nature of asphaltene and mineralogy of reservoir rock affect the adsorption of
asphaltene onto the rock surface. The basic goal of the present study is to assess the …

Asphaltene precipitation/deposition is one of the main problems in petroleum industry at
various stages. In this study, various controlling factors on the adsorption of different types of …

In this study, based on a new procedure, asphaltene fractions of Sarvak oil samples were
determined based on their adhesion to calcite, dolomite, and sandstone surfaces and their …

This study investigates the properties of asphaltene fractions in porous media and their role
in reducing permeability and porosity. Based on the classification of a whole asphaltene …

In this work, amount of asphaltene adsorption onto the carbonate and sandstone rock
samples was investigated at various initial concentrations of asphaltene in oil. Asphaltene …

Wettability alterations, permeability reduction of reservoir rocks, and oil production decline
may occur as a consequence of asphaltene adsorption and deposition on the surfaces of oil …

Asphaltene adsorption on minerals induces wettability alteration in porous media, which, in
turn, affects capillary pressure, relative permeability, and residual oil saturations. The …

In this study, a whole asphaltene sample was first aged with five dolomite core samples.
Then the core samples were washed with toluene; this asphaltene was named the bulk sub …

In this work, experimental studies were conducted to determine the effect of asphaltene
deposition on the permeability reduction and porosity reduction of carbonate, sandstone and …
