“…Fighting the fingering of injected fluids requires to increase their capillary number [25,26]. This wellknown trouble led to the use of viscous, but shear-thinning fluids in oil recovery [14,[27][28][29][30]. These behaviors, observed for associative polymers like xanthan and for foams, are used for the ISR of contaminated soils [20,21,23,[31][32][33][34][35][36][37][38][39][40][41][42].…”
