    摘要: The invention is a method for real-time updating of a geological model using dynamic data while maintaining the coherence thereof with static observations. An initial set of reservoir property maps, obtained from stochastic simulations of a random function, are available. Parameters providing new realizations of the random function when applied to the set are selected. New maps are created using initial values of the parameters. As soon as new dynamic data are available, the parameters are modified to reduce a difference between the simulated data for perturbed models and the measured data. Finally, the reservoir is developed using a modified development scheme to account for the deformed maps.
