Fluid Flow Visualization through Porous Media

We have built a set-up enabling direct visualization of fluid displacement and interaction in a transparent porous media at pore scale resolution. We have been able to image successive 2D planes in order to reconstruct the 3D configuration of residual oil after secondary imbibition for mobilization and displacement experiments. We visualized the dynamics of primary drainage and secondary imbibition and studied the non wetting phase ganglia morphologies. For small Ca, the ganglia configuration does not change significantly. However as Ca is increased above a certain threshold we observed that large ganglia break up into smaller ganglia, with the associate decrease in residual oil. By comparing the blob configuration between a mobilization experiment and a displacement experiment the work has clearly delineated the importance of knowing history, and has demonstrated that displacement is likely to be more efficient in recovering oil.
