This work proposes a paradigm shift where reservoir simulators become the tools of choice for both geological screening and detailed numerical simulations. To make this possible, the traditional fully-implicit method is replaced by a novel sequential implicit formulation, where fast fluid flow solutions can be obtained by leveraging an algebraic multiscale solver. This new approach bridges cross-disciplinary silos, facilitating knowledge transfer between geologists and reservoir engineers, with ample possibilities for new synergies and workflows.
