The need of a reliable solution to large numerical models poses an issue regarding the efficiency of the employed linear solver, both in terms of accuracy and computational cost. In this work, we present an analysis on the performance of two families of block preconditioners, properly designed to handle the linearized system of equations that arises from the discretization of flow problems in reservoirs by means of the Mimetic Finite Difference Method.
