摘要
Methods, systems, and computer readable media are provided for fast updatingof oil and gas field production optimization using physical and proxysimulators. A base model (30) of a reservoir (100), well (100), or a pipelinenetwork (100) is established in one or more physical simulators (26). Adecision management system (24) is used to define uncertain parameters formatching with observed data (114). A proxy model is used to fit the uncertainparameters to outputs of the physical simulators (26), determine sensitivitiesof the uncertain parameters, and compute correlations between the uncertainparameters and output data from the physical simulators (26). Parameters forwhich the sensitivities are below a threshold are eliminated. The decisionmanagement system (24) validates parameters which are output from the proxymodel in the simulators (26). The validated parameters are used to makeproduction decisions.
