Utilization of the abundant heavy crude oil resources has been accepted as an effective
approach to tackle the shortage of light oil supply in the coming decades. However, the high …

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 …

Understanding the phase behavior of the various fluids present in a petroleum reservoir is
essential for achieving optimal design and cost-effective operations in a petroleum …

The precipitation of asphaltenes in two Mexican crude oils was measured using a
combination of high‐pressure isothermal expansion and atmospheric titration with n …

Precipitation of asphaltene is considered as an undesired process during oil production via
natural depletion and gas injection as it blocks the pore space and reduces the oil flow rate …

A number of different models that have been applied to modeling of asphaltene precipitation
and estimating asphaltene solubility in various systems are critically reviewed. Particular …

An efficient modelling technique based on the representation of the precipitated asphaltene
as a pure dense phase is presented. The success of the approach is based on the division …

Asphaltene precipitation is a perennial problem in producing and refining crude oils. To
avoid precipitation, it is useful to know the solubility of asphaltenes in petroleum liquids as a …

Asphaltenes represent one of the major potential flow assurance problems in the upstream
oil industry. Asphaltene precipitation determination is a key step in studying the asphaltene …

The effect of temperature, molecular weight of n-alkane precipitants and dilution ratio on
asphaltene precipitation in a Chinese crude oil have been studied experimentally. The …
