ABSTRACT: We developed a numerical model to simulate steamwater injection into fractured diatomite formations. To mitigate the high nonlinearity in both the EOS of the water substance and the behavior of a fracturematrix system, our formulations are simplified from actual system behavior but preserves the most fundamental behaviors of the steamwater fracturematrix system.
