STUDY ON THE CHANGE OF ASPHALTENE CONTENT OF THE RECOVERED OIL DURING C02 INJECTION FOR LIGHT OIL

Gas injection is one of the oldest and widely known methods in the Enhanced Oil Recovery (EOR) process. Injection of C02 resulted in the increasing of oil recovery and created a permanent storage of C02 in geological formation when it was injected in a particular reservoir conditions. Unfortunate...
