Multiple-point geostatistical simulation (MPS) has recently become popular in stochastic hydrogeology. primarily because of its capability to derive multivariate distributions from a training image (TI). However. its application in three-dimensional (3-D) simulations has been constrained by the difficulty of constructing a 3-D TI. https://www.infonoticiasgandia.com/product-category/sifters/
