.... The sandstone permeability is roughly 0.1 ?m 2 while the unconsolidated sand permeability is 6.7 ?m 2 . Experiments with and without cross flow between the two porous media were conducted. To prevent cross flow, the cylindrical face of the sandstone was encased in a heat-shrink Teflon sleeve and the annular...
