Abstract:

The objective of this research study is to introduce of new chemical component to Enhanced Oil Recovery (EOR). Crude Terephthalic Acid (CTA) as a macromolecule and one of the isomers of the three phthalic acids is an intermediate product of petrochemical industries which can be used as an alternative to the traditional Hydrolyzed Poly Acryl Amide (HPAM). Crude Oil samples from an Iranian oil field were selected to be used during the flooding tests. Comparison between water flooding and CTA flooding as a secondary oil recovery process revealed that the recovery was improved by 10% when CTA was used. The effect of various injection rates and different concentration of chemical solutions on the recovery factor have been checked and the results showed that high CTA concentrations and low injection rates are the optimum criteria for higher oil recovery efficiency and this chemical as a viscous surfactant and IFT reducer, would be stable in extreme conditions of high salinity and high temperature and therefore, it can be used for reservoirs with high salinity and temperature, too.
