Pore-scale dynamics and the multiphase Darcy law
A pore-scale experimental investigation of microscopic steady-state flow during co-injection from very low to high flow rates in the pore space of a sandstone is applied using 4D synchrotron X-ray micro-tomography to advance our understanding of flow regimes. We report the results of micro-CT imaging experiments directly visualizing the simultaneous flow of both a wetting and a non-wetting fluid through a Bentheimer sandstone, at pore-scale resolution. For small flow rates, both fluids flow through unchanging, distinct, bicontinuous 3D pathways. At higher flow rates, however, the non-wetting fluid continually breaks up into discrete ganglia; these are then advected through the medium. We propose that the non-wetting fluid breaks up when the sum of the viscous forces exerted by the wetting and the non-wetting fluids exceed the capillary forces at the pore scale.

1. A dry scan was taken with 2 MPa confining pressure. 2. The brine-saturated sample was scanned. A back pressure of 2,000 kPa was set for the whole system. 3. Oil was injected at 2 mL/min for 30 minutes to reach the initial water saturation. 4. Water and oil were injected when fw were 0.15 and 0.3 by keeping the total volumetric flow rate fixed at 0.02 mL/min for one and half hours respectively. 5. Water and oil were injected at equal flow rate of 0.01 mL/min respectively. At the same time, the pressure drop across the whole sample was recorded. Two more hours were waited after the pressure stabilized. Successive scans were taken from the start without stopping. 6. The total flow rate was increased to 0.04 mL/min, 0.08 mL/min, 0.4 mL/min, 0.8 mL/min and 1.2 mL/min step by step when fractional flow was kept at 0.5. For each flow rate, two more hours were waited until steady state.
