method to quantitatively determine the evolution of permeability andthe porosity of the porous medium during diagenesis.we define a scenario and initial structure of diagenesisthe network ofthe pores of the porous medium. we build a representation of the network of poresmediuma model of the pnm. then, for each stage of diagenesis scenario isthethe following steps: determining the ion concentration in the pore wallsandchannels in the nwp model for precipitation reaction or dissolution inaccording to the scenario, and we infer a change in the geometry of the model.nip. in order tothe nwp model, as amended, is calculated geometrically and porosity.permeability from darcy's law. we repeat these steps as a function ofscriptof diagenesis. finally, we deduce a law between the soil's permeabilityporous andthe porosity of the porous medium during diagenesis.application in particular to the exploitation of oil deposits.
