FIELD: oil and gas industry.
SUBSTANCE: group of inventions refers to the area of modelling and can be used for well performance forecasting. The method contains the stages, during which: input data influencing output index are identified, a subset of input variables is indentified when the above subset has relatively higher impact on output index. The model of physical properties is plotted in order to forecast output index as subset function of the set of input variables. The suggested changes in the subset from set of input variables are ranged against probability using the model of physical properties. Physical system performance is forecast based on the level of assumed changes.
EFFECT: well simulation forecasting.
