    "abstract": "We investigate the stabilization mechanisms due to viscous forces in the\ninvasion front during drainage displacement in two-dimensional porous media\nusing a network simulator. We find that in horizontal displacement the\ncapillary pressure difference between two different points along the front\nvaries almost linearly as function of height separation in the direction of the\ndisplacement. The numerical result supports arguments taking into account the\nloopless displacement pattern where nonwetting fluid flow in separate strands\n(paths). As a consequence, we show that existing theories developed for viscous\nstabilization, are not compatible with drainage when loopless strands dominate\nthe displacement process.",
