Comparison study on sag foam model parameters in different reservoir simulators

In order to model the foam behavior inside the porous media, various studies have been conducted and several models developed. Some of the commercial reservoir simulators equipped with these foam models. However, the contribution of each model parameter and their effect on the foam behavior are varied between different simulators. This study aims to compare two different well-known foam models and reveal the contribution of foam model parameters using the numerical simulation study. A synthetic model for surfactant-alternating-gas flooding in sand pack system is built using simulators. Design of expert is utilized to design different simulation scenario based on different foam models parameters. Simulations were performed for all scenarios and the results are analyzed by ANOVA to investigate the effect of different parameters on foam mobility reduction factor. The results show the effect of each parameter on mobility reduction factor in both models. Also, it illustrates that some parameters like critical water saturation are not important in ECLIPSE and CMG models however it has a moderate effect on foam mobility reduction in UTCHEM model. © Medwell journals, 2017.
