This paper presents some new results of theoretical modeling on permeability anisotropy in heterogeneous porous media. It is shown that the lineation of heterogeneities results ·in permeability anisotropy. However, to produce strong anisotropy, the permeability contrast between the lineated high permeability region and the background must be very high. We demonstrate this using two examples. Th...
