We consider the formation of viscous fingers in porous media using the boundary-integral method with particular application to a recent experiment involving a Hele-Shaw cell filled with glass beads. When the less viscous fluid wets the beads we can account for the patterns as ordinary viscous fingers in the presence of large noise.
