Patent ID: 8818781

Claim:
A method for operating an oil pool according to an operating scheme based on a representation of the pool including obtaining a meshing associated with at least one map of a property of the pool by a stochastic simulation of a first random function, in which dynamic data are acquired during operation of the pool and the at least one map is modified to minimize an objective function measuring a difference between the dynamic data which are simulated by the representation of the pool and a flow simulator comprising: i. choosing at least one correlation coefficient between the first random function and at least one second random function with an identical mean and covariance; ii. modifying the at least one map by performing a cosimulation of the first random function and the at least one second random function by using the at least one correlation coefficient; iii. modifying the at least one correlation coefficient and reiterating the cosimulation with the at least one modified correlation coefficient in order to produce a random function with an identical mean and covariance as the first random function until the objective function converges toward a minimum; iv. changing the pool operating scheme by accounting for the modified map; and v. operating the pool implementing the modified operating scheme.
