  • Abstract

In this paper, operator splitting scheme for dynamic reservoir characterization  by  binary level set method is employed. For this problem, the absolute permeability  of the two-phase porous medium flow can be simulated by the constrained augmented Lagrangian optimization method with well data and seismic time-lapse data. By transforming the constrained optimization problem in an unconstrained one, the saddle point problem can be solved by Uzawas algorithms with operator splitting scheme, which is based on the essence of binary level set method. Both the simple and complicated numerical examples demonstrate that the given algorithms are stable  and efficient and the absolute permeability can be satisfactorily recovered.
