摘要
The method involves selecting a perturbation method utilizing perturbation parameters for perturbing reservoir property maps. The parameters are modified by applying an Ensemble Kalman Filter method (EnKF) to the parameters and dynamic data (DDn) that are acquired during development of a reservoir and simulated by a representation of the reservoir and a flow simulator. The maps are modified by applying the perturbation method with the modified parameters. A development scheme of the reservoir is adjusted by accounting for the modified maps. The reservoir is developed using the modified scheme. The perturbation method is a gradual deformation method, a pilot point method, a probability perturbation method or a cosimulation perturbation method.
