  We study the interplay between viscous, capillary and gravitational forces in two-phase flow in a threedimensional porous medium, with the use of an optical scanner based on index-matched medium and fluorescent fluids. A more viscous, denser, fluid is injected into a less viscous, less dense fluid in a 3D porous medium, comprised of randomly packed glass beads of uniform size. We tune the injection rate over 10 experiments. Experience from the 2D scenario suggests that with a slow injection rate capillary and gravitational forces will dominate, and we should observe an unstable displacement and fingering. Conversely, with a high injection rate, viscous forces will dominate, leading to a more stable displacement and a narrower invasion front. How do the 2D findings hold up in the 3D scenario? We confirm the qualitative findings from the 2D experiments and establish a clear regime change, from unstable to stable displacement. We seek to derive a dimensionless number to quantify the relevant balance of forces and consider this number in relation to the invasion pattern. We characterize the invasion by Minkowski-functionals and fractal dimensions and seek relations between the found geometries and the derived dimensionless numbers.
