Asphaltene Precipitation Modeling of Sadi Formation in Halfaya Iraqi Oil Field
Journal of Engineering, 2019 Asphaltene is a component class that may precipitate from petroleum as a highly viscous and sticky material that is likely to cause deposition problems in a reservoir, in production well, transportation, and in process plants.
