Abstract
To date, the most efficient solver used in the petroleum industry for the resolution of linear systems in reservoir simulation is the generalized conjugate-gradient acceleration method called Bi-CGSTAB. However, difficulties still appear in matrix resolution when the Bi-CGSTAB method is used without an appropriate preconditioner.
