Heavy and extra heavy crude oils usually have a high weight percentage of asphaltene,
which could induce many problems during production to refining processes. Also …

In this paper, oil recovery and permeability reduction of a tight sandstone core sample in
miscible CO2 flooding processes due to asphaltene deposition were studied using an …

The effect of CO 2 injection on the structure and transport properties of confined asphaltenes
in 6 nm slit-shaped calcite nanopore was studied using molecular dynamics simulations …

Asphaltene deposition is an issue that has received much attention since it has been shown
to be the cause of major production problems in enhanced oil recovery processes …

Blockage in reservoirs caused by asphaltene deposits and inorganic interactions is a
serious problem that may exacerbate the complexity of displacement characteristics in …

In this work, asphaltene adsorption in a sandstone core sample under dynamic conditions
and during miscible CO 2 injection was studied using live oil sample which is close to real …

This paper reports a set of experiments carried out to examine asphaltene deposition in a
glass microcapillary pipet, as a proxy to asphaltene deposition in reservoir pores. A new …

The aggregation and deposition of colloidal asphaltene in reservoir rock is a significant
problem in the oil industry. To obtain a fundamental understanding of this phenomenon, we …

Asphaltenes are known as the “cholesterol” of crude oil. They form nanoaggregates,
precipitate, adhere to surfaces, block rock pores, and may alter the wetting characteristics of …

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 …
