Percolation threshold and scattering power law of gelatin gels

Y. Piñeiro, M. A. López-Quintela, J. Rivas, D. Leisner
2009 Physical Review E  
Power laws observed on the gel point-mainly obtained by dynamic light scattering ͑DLS͒-are considered to be the signature of some special dynamic phenomena ascribed to the appearance of a percolation cluster  ...  We ascribe the percolation point to the time where the scattering medium mode diverges. This mode is sensitive to the clusters' growth and diverges when the system attains the percolation threshold.  ...  thermal conditions, different from random walk ͑RW͒ configurations obtained by a simple percolative scheme.  ...

A Mechanistic Pore-Scale Analysis of the Low-Salinity Effect in Heterogeneously Wetted Porous Media [article]

Michael G. Watson, Steven R. McDougall
2019 arXiv   pre-print
For networks that contain spanning clusters of both water-wet and oil-wet (OW) pores prior to flooding, our results demonstrate that the OW pores contain the only viable source of incremental oil recovery  ...  The wettability of the pore structure is modified in regions where water salinity falls below a critical threshold, and simulations show that this can have significant consequences for oil recovery.  ...  ACKNOWLEDGMENTS The authors would like to thank TOTAL S.A. for their invaluable technical support and financial assistance.  ...
