摘要

Methods to update a set of models for reservoir and to process data in a set of models, program storage device and apparatus for simulation to update a set of models of reservoir. A method, system and apparatus for updating model of reservoir in real time using set of Kalman filters are described.The method includes a step of conformity to put variables in static and dynamic state, in accordance with each other during a time step update. Also, an iterative attenuation method is used in conjunction with the step of conformity to take into account C Aracteru00edsticas non Gaussian and non-linear in a system.Also, a method of re experiment is described, which reduces the size of the set of models of reservoir should be updated.
