Modeling of asphaltene precipitation using CPA-EOS for live oil in an iraqi oil well (original) (raw)
Asphaltenes are a solubility class that is described as the heaviest and most polar component of crude oil. Asphaltene precipitation (AP) and deposition during oil production, processing, and transportation are major issues for the oil industry. The present research describes the phase behavior and Asphaltene precipitation for live oil from a well in south of Iraq. The research highlights numerous key methodologies for modeling Asphaltene phase behavior using a combination of Multiflash software and the cubic-plus association equation of state (CPA-EOS) model for AP. The outputs of this suggested combination are the Asphaltene precipitation Envelope and AP Curve, from which we can predict the operation conditions for occurring AP. Prediction of these conditions can enhance reservoir performance and production systems to reduce AP by controlling the reservoir variables that affect AP (i.e. pressure, temperature and fluid composition).
