Claim Text:
1. A multi-level reservoir history matching method that comprises: generating a first history-matched model using at least one updated model parameter derived from one or more existing model parameters; generating a plurality of second history-matched models by applying a probabilistic inversion to the first history-matched model; deriving a plurality of third history-matched models from the plurality of second history-matched models; generating a plurality of dynamic simulation realization sets using each of the plurality of third history-matched models; ranking each of the plurality of third history-matched models based at least in part on the plurality of dynamic simulation realization sets to identify a highest ranked third history-matched model; and presenting, by a computer, a production forecast via a display to a user based on the highest ranked third history-matched model.
