Abstract

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. Unfortunately, when the C02 was injected to the light oil reservoir, it will cause severe asphaltene problems especially in light oil reservoir which contained low percentage of asphaltene content. Asphaltene will precipitate and deposited in the reservoir, well bore, tubing as well as surface facilities. Presence of asphaltene may reduce the permeability of the reservoir, changing the wettability of reservoir and plugging the well bore and tubing which cause of loss in production. This project studied the changes of asphaltene content (weight %) in recovered oil during C02 injection using Dulang crude oil at three (3) different injection pressures. Recovered oil was collected every 4 cc of pore volume has been injected with C02 during core flooding at 3 different injection pressure which are 2000, 2300 and 2600 psig. Asphaltene content in the recovered oil was measured using ASTM (D3279-07) standard test method. Results showed the decreasing trend of asphaltene content in the recovered oil for all the three (3) injection pressures. As the injection pressure decreased, the asphaltene precipitation in the porous media increased as well decrease the oil that can be recovered during the C02 injection.
