| Abstract: | Stochastic modeling is being increasingly used to generate the numerical models of reservoir parameters. The basic principle of simulated annealing method is described. The simulated annealing method is used to simulate the 2 D permeability distribution from multi well test information. The permeability simulation realizations provide a solid foundation for reservoir simulation, which is helpful to performance prediction and risk conscious reservoir management. |
