Claim One:
1. A non-transitory computer readable medium storing a computer program which when executed by a processor of a computer performs a method of producing a production simulator, for simulating a mature hydrocarbon field, providing quantities produced per phase, per well, per layer or group of layers and per time as a function of production parameters, wherein said production simulator is defined by a set of parameters α within a space of solutions, matches history data of said mature hydrocarbon field and exhibits a good forecast reliability, which can be characterized, according to a Statistical Learning Theory, by low forecast expected risk R(α) associated with said parameters α, the method comprising the steps of: defining initial detailed reservoir partition, rock properties, laws of reservoir physics and laws of well physics, upscaling said reservoir partition, rock properties, laws of reservoir physics and laws of well physics until a Vapnik condition is verified, and optimizing said production simulator by choosing from among production simulator candidate solutions, a candidate solution minimizing a forecast expected risk R(α).
