Claim One:
1. A method for scaling data of a reservoir model, for example a hydrocarbon reservoir, implemented by means of a computer, comprising the steps of: defining (S 100 ) a set of reservoir models each comprising a number of meshes with given dimensions, these meshes each comprising a number of cells; and receiving statistical data relative to porosity and permeability, applicable to each of the models of said set, for each of the models: assigning (S 300 ) to the cells, values of permeabilities k Hi and of porosity Φ Hi , depending on said statistical data; for each mesh of the model, scaling (S 400 - 800 ) a permeability value K H of the mesh, on the basis of a mean power formula K H ω H ∝Σk H i ω H relating the permeability K H of the mesh to the permeabilities k Hi of the cells via the power coefficient ω H of the Noetinger-Haas relationship ω H = Arctan α π - Arctan α , this power coefficient ω H being analytically modified in order to correct a non-ergodicity bias due to the dimensions of the relevant mesh; and determining (S 900 ) permeability and porosity values of the reservoir with the help of the set of reservoir models, using the permeabilities of scaled meshed.
