Abstract
The application of any empirical correlation is recommended only within its range of validity. Nonetheless, the indiscriminate usage of black oil correlations for fluid modeling happens frequently. This work evaluates Lasater’s (1958) correlation for the solution gas-oil ratio (Rs) fluid property specifically for oils with high CO2 content and high GOR. The correlation results are compared to experimental data, and high prediction errors are observed. Finally, the influence of the Rs prediction error on the flow simulation is assessed.
