METHOD FOR UPDATING A RESERVOIR MODEL IN REAL TIME FROM DYNAMIC DATA WHILE RETAINING ITS CONSISTENCY WITH STATIC COMMENTS

摘要

A method for updating a geological model in real time using dynamic data while maintaining its consistency with static observations. An initial set of maps of a property of the deposit obtained by means of stochastic simulations of a random function is available. We choose parameters that, applied to this set, provide new realizations of the random function. New maps are created using initial values of these parameters. As soon as new dynamic data is available, the parameters are modified to reduce the gap between the simulated data for the disturbed models and the measured data. Finally, the deposit is exploited by implementing a modified exploitation scheme to take into account the deformed maps.
