Although lots of experiments have been done in enhanced oil recovery field, the number of experiments which consider the effects of local and global heterogeneity on efficiency of enhanced oil recovery based on the ASP flooding is low and rarely done. In this research, we have done numerous experiments of water flooding and ASP flooding on a five spot glass micromodel in different conditions. In these experiments, five different micromodels with three different pore structures are designed. Three models with different layer orientation, one homogenous model and one heterogeneous model are designed. The results show that maximum EOR recovery factor will happen in a situation where the layers are orthogonal to the path of mainstream and the minimum EOR recovery factor will happen in a situation where the model is heterogeneous. This experiments show that in ASP flooding, with increase of angles of layers the EOR recovery factor will increase and this recovery factor is strongly affected by local heterogeneity around the injection zone.
