... ABSTRACT: We experimentally investigate the effect of the pore fluid on AE in four sandstone plugs cored from a homogeneous slab. These plugs were fully saturated with brine, mineral oil, and hexane, while one of them remained dry. AE level was highest in the hexane-saturated sample, smaller...
