摘要

The invention relates to a method for operating a geological reservoir, which may consist of operating a hydrocarbon reservoir or a gas (for example CO2) storage reservoir. The exploitation (EX) of the geological reservoir is carried out according to an exploitation diagram (SE) defined from a reservoir model (MR), said reservoir model being calibrated (CAL) with respect to dynamic data (DD ). According to the invention, the calibration (CAL) is carried out by calculating an objective function (OF) for a set of reservoir models. Said objective function (OF) makes it possible to determine an analytical conditional distribution law (POST) of the uncertain parameters of said model, this law is then used to generate new reservoir models added to said set of reservoir models.
