The permeability of samples, especially rock samples, is determined by immersing the sample in a dye solution to permit dye to diffuse into the sample, rinsing remaining dye solution from the surface and then either placing the rinsed sample in a leachback solution to permit dye to diffuse out into the leachback liquid or else simply allowing the dye to diffuse out onto the surface of the sample, thereby causing a coloration indicative of the permeability of the sample. The method can be practiced on slab samples or drill cuttings.
