Then, at least one hydrologic zone is delimited using a hydrologic model, and at least one chemical composition of the fluids and a direction of 10 circulation of the fluids are determined in each cell located in the zone. At least the chemical composition of the fluids, the mineralogical composition and the porosity are then updated in each cell of the gridded representation by means of a diagenetic model comprising a hydrologic flux balance, established using at least the directions of circulation of the fluids and from which a cell visiting order is determined for the fluids, and 15 comprising a reaction kinetic model, modelling interactions between the chemical composition of the fluids and the mineralogical composition in the cell. - Application: notably petroleum exploration and exploitation. 10305647_1 (GHMatters) P108828.AU1/2 F D x 0 M z Figure IA 0 COL1 COL2 ZM z - COL3 Figure 1B 0 100 0 100 0 100 c1 -- $ (%) C2 -- N C() 4 c7 COL1 COL2 COL3 Figure 1C2/2 P P 1i Mi-$1X2 ~M2-42 X l 2M3-4r3 M-$r1 X3 M4-4 X2 M-r X4M3-r3 z4 wp X3 4 X5 WP X3 5 7X Xmoy 8 :r X 8 WM MM~gWM Xmarnn XmarinC COLl COL2 zv ZP ZM Figure 2
