This emulsified acid formulation utilizes organically surface modified nanoparticles that provide higher temperature stability to the emulsified acid. The formulation of enhanced emulsified acid does not require...

Secondly, the designed SW-solution also modifies the fluid-fluid interaction by diminishing the shielding effect of the electrical double layer (EDL), and consequently, enhancing the foam film stability ( Hassan et al ., 2020a , 2020b , and 2020c ). Abstract...
