Method to evaluate a chart for the production of an underground largement taking into account the uncertainties

摘要

- Method for evaluating a diagram of the production of an underground taking into account the uncertainties. - it selects the input parameters of a flow simulator, characterizing the bearing and the production scheme. It is constructed an analytical model approached, making it possible to predict the responses of the reservoir. It defines a degree of precision dp that it is desired to obtain this degree of precision dp measuring the difference between the responses of the model and those of the simulator. It calculates the degree of precision dp (m) of the predictions of the model. It is constructed in a plane of experiments so as to select the simulations to be performed, to adjust the model. The simulations selected by the plane of the experiment, and then, for each of the simulated responses by the simulator, one adjusts the analytical model with the aid of a method of approximation. It is repeated until the desired degree of accuracy dp is achieved. Finally, the diagram of production, by analyzing the responses of the bearing predicted by the analytical model approach. - application in particular to the use of oil deposits, for example.
