ASFALTENOS, UN DAÑO SEVERO EN YACIMIENTOS ALTAMENTE SUBSATURADOS DE ACEITE VOLÁTIL

Revista Fuentes El Reventón Energético, 2011
Aphaltene organic precipitation and deposition is known as a severe problem at reservoir level, especially in high sub-saturated reservoirs, due to the asphaltic deposition is extended beyond wellbore.

Modeling of asphaltene precipitation - part I: comparative study for asphaltene precipitation envelope prediction methods

Iraqi Journal of Chemical and Petroleum Engineering
   The solubility of asphaltenes in crude oils is predominantly influenced by variations in temperature, pressure, and oil composition. These alterations can precipitate asphaltene deposition, resulting in diminished permeability, obstruction of wells ...

A Fundamental Study of Asphaltene Deposition

, 2015
Asphaltenes are a solubility class of petroleum crude oil that can destabilize and deposit in both upstream and downstream processes. In this study, asphaltene deposits were generated in metal capillaries by heptane addition to crude oils, and it was ...

Investigation into mechanisms and kinetics of asphaltene aggregation in toluene/n-hexane mixtures

Petroleum Science, 2019
Determining the rate of asphaltene particle growth is one of the main problems in modeling of asphaltene precipitation and deposition. In this paper, the kinetics of asphaltene aggregation under different precipitant concentrations have been studied. The
