Methods, systems, and computer-readable media for fast updating of oil and gas field production models with physical and proxy simulators

摘要

Methods, systems, and computer readable media are provided for fast updatingof oil and gas field production optimization using physical and proxy simulators.A base model (30) of a reservoir (100), well (100), or a pipeline network (100)is established in one or more physical simulators (26). A decision managementsystem (24) is used to define uncertain parameters for matching with observeddata (114). A proxy model is used to fit the uncertain parameters to outputs ofthe physical simulators (26), determine sensitivities of the uncertain parameters,and compute correlations between the uncertain parameters and output data fromthe physical simulators (26). Parameters for which the sensitivities are belowa threshold are eliminated. The decision management system (24) validates parameterswhich are output from the proxy model in the simulators (26). The validated parametersare used to make production decisions.
