New study challenges 100-year-old law on fluid flow in rocks
Using 3D imaging, UK-based researchers have discovered fluid flows through rocks are very unstable, compared to the 100-year-old Darcy's Law which describes stable fluid movement through microscopic pathways. However, researchers claim, the pathways last only for tens of seconds at most, before re-arranging and forming new pathways. The findings would enable modelling oil, CO2 storage, team said.
