  3. Abstract:
  4. A precise semi-empirical correlation for the calculation of interfacial tension (IFT) between the carbon dioxide and paraffin group to be used in an enhanced oil recovery process and the chemical industry is introduced. Genetic programming and dimension analysis (GPDA) are combined to create a correlation for the calculation of the equilibrium interfacial tension of the carbon dioxide and paraffin group, based on the explicit functionality of the pressure and temperature. The parameters of the correlation consist of critical temperature, critical pressure, density of paraffin at normal temperature, and diffusion coefficients. The pool of experimental data for developing the correlation consists of 400 randomly gathered data points. To check prediction capability of the correlation 200 data points which are not participated in developing part are used. The average absolute percent deviation (AAD %) for comparing the results with the experimental data is found to be 5%, which demonstrates the accuracy of the presented correlation
