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 ...
