Deduction of New Correlation and Computational Programme to Estimate Bubble and Dew Points Pressures using the Equation of State

Abstract

In this thesis new correlation of bubble point pressure (Pb) has been created using software called VariReg depending on the theory of Artificial Neural Networks (ANN). A computer program has been designed using MATLAB® software to simplify the calculation of the bubble and dew points pressures depending on the theory of the equation of state (EOS), the program includes some of others known empirical correlations of bubble point and dew point pressures, and a comparison study between results of these programs (VariReg and developed program) and laboratory. The program verified Sudanese oil fields PVT data. The program contains the others known empirical correlations of bubble and dew points pressures for the purpose of comparison. From the statistical results; the new developed model found to be more precise due to the large correlation factor (R2) obtained and lowest degree of errors compared to the known models.
