EXPERIMENTAL INVESTIGATION OF THERMALLY STABLE SILICA NANOPARTICLES IN POROUS MEDIA
The instability of silica nanoparticles (SNPs) in saline water at high temperature makes these type of nanoparticles inefficient as enhanced oil recovery agent. This study aimed to investigate the permeability impairments of thermally stable partially hydrophilic silica nanoparticles (PH-SNPs) on di...
