Claim:
A method for simulating sandstone deposition comprising: (a) estimating grain size distribution and mineral composition distribution of grains in the sandstone; (b) simulating sedimentation of grains using the grain size distribution and the mineral composition distribution of the grains; (c) simulating compaction of the sedimented grains; and (d) simulating cementation of the compacted grains; wherein the type of deformation simulated during the compaction simulation of grains of step (c) is chosen from the group consisting of elastic deformation and any combination of elastic deformation and ductile deformation; and wherein the elastic deformation is modeled by using a following equation: dV = Vr Vo = κ ⁢ ⁢ σ wherein: Vr=volume of the grain in presence of a uniform stress field, Vo=volume of the grain in under atmospheric conditions, σ=effective stress (MPa), κ=a compressibility constant (MPa −1 ).
