METHOD AND SYSTEM FOR CREATING HISTORY-MATCHED SIMULATION MODELS

摘要

A method for matching production history to flow simulations includes identifying a plurality of parameters that control an objective function measuring the mismatch between a flow simulation response in a parameter subspace and a production history. A value is calculated for an objective function and for a static measurement at each of a plurality of experiments in the parameter subspace. These results are used to develop a mathematical relationship between one or more static measurements and the objective function. During subsequent adjustment of the simulation model, a target window in the objective function is identified, and flow simulations are performed for each modified model that is predicted from the static geologic measurement to produce an objective function within the window. An objective function of each flow simulation to the production history is calculated and the procedure is iterated until the objective function is within a target range.
