Screening of inhibitors for remediation of asphaltene deposits: Experimental and modeling study
Petroleum, 2018 One of the most severe problems during production from heavy crude oil reservoirs is the formation of asphaltene precipitation and as a result deposition in the tubing, surface facilities and near wellbore region which causes oil production and ...

Prediction of the Gas Injection Effect on the Asphaltene Phase Envelope
Oil & Gas Science and Technology, 2015 Asphaltene instability may occur when pressure, temperature and compositional variations affect the reservoir oil. Permeability reduction, wettability alteration, and plugging of wells and flow lines are the consequences of this phenomenon. Therefore, it
