Finite Peclet Extensions of Dagan's Solutions to Transport in Anisotropic Heterogeneous Formations

Dagan's [1984] landmark solution for transport in heterogeneous porous formations is extended to the case of finite Peclet numbers. It is suggested that pore‐scale dispersion matters only with reference to transverse spreading, and that Dagan's solution, valid for P e =∞ is an adequate approximation in a wide range of finite Peclet numbers.
