METHOD FOR DEVELOPING AN OIL FIELD USING A RESERVOIR MODEL THAT IS GRADUALLY DISTORTED THROUGH CO-SIMULATIONS

摘要

A method of operating a petroleum field from a reservoir model deformed gradually by means of cosimulations. A map of a property of the deposit obtained is obtained by means of a stochastic simulation of a first random function. We choose a correlation coefficient between this first random function and a second random function with the same mean and the same covariance. Then, the map is modified by cosimulating the two random functions using the correlation coefficient. The correlation coefficient is modified and the cosimulation step is repeated to deform the card and to minimize an objective calibration function. Finally, the deposit is exploited by implementing a modified exploitation scheme to take into account the deformed map.
