ABSTRACT
In this work, the effect of formation water concentration in the emulsion with oil on the amount of asphaltene precipitation was studied. In addition, the effect of flow rate and asphaltene concentration on formation damage of Iranian carbonate core samples was investigated. A new asphaltene inhibitor was used for preventing asphaltene precipitation. Performance of the inhibitor was studied under static and dynamic conditions. The inhibition efficiency reached 77% at a concentration of 3% of asphaltene inhibitor. Also, adsorption rate of the inhibitor was determined at different inhibitor concentrations. The results showed that the adsorption rate is increased by increasing the inhibitor concentration. However, the adsorption rate remained almost unchanged at higher concentrations.
