Asphaltene is the heaviest and most polar fraction of crude oils, which is usually defined as
a solubility class, soluble in light aromatics, benzene and toluene, and insoluble in paraffins …

Formation damage issues typically arise at different recovery stages of unconventional
oil/gas and geothermal energy in various petroleum and hydrological geosystems. A lack of …

We have investigated the interfacial behavior of asphaltene molecules at the oil–water
interface using molecular dynamics simulations. Oil precipitants and solvents are …

Asphaltenes and maltenes are defined operationally by solubility (in, eg, heptane).
Asphaltenes self-associate in solution and form putative nanoaggregates composed of …

CO 2 huff-n-puff is a potential approach to improve the oil displacement efficiency in the
deep reservoirs, which can achieve carbon sequestration and efficient oil production …

Although asphaltenes are always present in crude oils, they create problems only when they
become insoluble in the remainder of the oil. A change in asphaltene solubility can occur …

Asphaltenes constitute a heavy aromatic crude oil fraction with a propensity to aggregate
and precipitate out of solution during petroleum processing. Aggregation is thought to …

Asphaltene flocculation and deposition from petroleum fluids may cause severe formation
damage and flow assurance challenges. Flocculation occurs when asphaltene aggregates …

This study discusses experimental and modeling results of asphaltene aggregation and
deposition using various n-alkanes as precipitants to destabilize asphaltenes from a crude …

Abstract A Deep Bed Filtration model has been developed to quantify the effect of solids
invasion from drilling fluids on the permeability of rock formations. The calculated particle …
