... to. The injection well pressure fluctuated according to the rates imposed on the model. The goal here is to investigate the relationship between the rate fluctuations and whether it reflects reservoir heterogeneity and preferential flow trends. To run the numerical experiments, we modeled, with Landmark s VIP...
