MODELING OF ASPHALTENE PRECIPITATION - PART I: COMPARATIVE STUDY FOR ASPHALTENE PRECIPITATION ENVELOPE PREDICTION METHODS

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

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 and auxiliary surface facilities, and ultimately, a reduction or cessation of production.Therefore, it
