Abstract: The present disclosure provides a workflow for modelling EOR flooding operations performed on a reservoir by separating front tracking from the reservoir simulation process, so that the fronts position and topology evolves in parallel with the coarse grid simulation, through modifications using machine-learning-trained correlations.

Abstract: A well placement plan optimization (300) which considers existing wells and heterogeneity constraints in a consolidated manner, rather than relying on individual decisions where to place the next producer (P1-P4), injector I1), or recomplete an existing producer as injector. These individual decisions are combined in a whole field optimization process, in order to discover a plan that maximizes an objective function such as net present value or recovery.
