Biography

M. (Matteo) Cusini is a Ph.D. Candidate in Petroleum Engineering, Delft University of Technology. He obtained his M.Sc from Energy engineering, Politecnico di Milano and Ecole Centrale Paris. The objective of his project is the development of an Algebraic Dynamic Multilevel (ADM) method for simulations of multiphase flow in geological formations. ADM combines the advantages of Dynamic Local Grid Refinement (DLGR) techniques with those of the multiscale finite-element (MsFE) [Hou and Wu 1997] and finite-volume (MsFV) [Jenny et al. 2003] methods. Based on the localized nature of many physical and chemical interactions taking place during the flow process the grid resolution is dynamically adjusted throughout the time-dependent simulation so that fine-scale resolution is used only in the regions of the domain where it is really necessary allowing for a reduction of the number of degrees of freedom. Starting from the fine-scale fully-implicit (FIM) system, ADM constructs a FIM system on a dynamically defined multilevel nested grid. The ADM system is algebraically described by employing sequences of adaptive multilevel restriction and prolongation (interpolation) operators. A different interpolation strategy is used for each primary variable (i.e., pressure and saturation) due to the mixed elliptic (or parabolic for compressible problems) hyperbolic nature of the governing equations.
