Modern production methods and environmental constraints demand chemical solutions. And
as oilfields age, the need for chemicals to ensure steady production increases. Production …

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 …

Asphaltenes are considered to be the heaviest and most polar fractions of crude oils and are
frequently implicated in problems encountered during production and refining as a result of …

Improved prediction of the onset of asphaltene precipitation may be achieved using
refractive index (RI) to characterize crude oils and their mixtures with precipitants and …

This document describes a state of the art concerning the flocculation of asphaltenes with
two major sections: characterisation of asphaltenes in various environments and modelling …

A new, two-component asphaltene solubility model (ASM) has been developed to predict
the phase behavior of asphaltenes in crude oils. Previous asphaltene solubility models have …

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 …

In this work, we propose a mathematical method for detection of the probable doubtful
asphaltene precipitation titration data. The algorithm is performed on the basis of the …

The “plus” fraction of a petroleum fluid is a complex mixture that has long defied traditional
chemical and thermodynamic treatments. This fraction of crude oil, by and large, cannot be …

Asphaltene precipitation and deposition in the reservoir, near-wellbore region, and pipelines
is one of the critical problems in flow assurance. It can cause a blockage of pore throats and …
