METHOD FOR OPERATING AN OIL POOL BASED ON A RESERVOIR MODEL GRADUALLY DEFORMED BY MEANS OF COSIMULATIONS

摘要

A method is disclosed for operating an oil pool based on a reservoir model gradually deformed by means of cosimulations. A map of a property of the pool is obtained by a stochastic simulation of a first random function. A correlation coefficient is chosen between the first random function and a second random function with an identical mean and covariance. The map is modified by a cosimulation of the two random functions by using the correlation coefficient. The correlation coefficient is modified and the cosimulation step is reiterated to deform the map and minimize a matching objective function. Finally, the pool is operated by implementing an operating scheme accounting for the deformed map.
