“…In low-pressure, scaled-model studies, the porous media has typically been very ' strongly water-wet glass beads (Doscher et al, 1982;Doscher, 1981;Sufi, 1990;Ahner and Sufi, ' 1990;Lookeren, 1977;I;arouq Ali, 1985). High-pressure models have used unconsohdated field sand of intermediate wettability (Quettier and Corre, 1988;Green and lsaa_zs, 1986), very strongly water-wet quartz sands (Butler and Yee, 1986;Ozen and Farouq Ali, 196"/;Coats, et al,, 1974), or very strongly water-wet consolidated sandstone, such as Berea sandstone (Ozen and Farouq Ali, 1967;Sarathi et al, 1990;Madden and Sarathi, 1985), or crushed Berea sandstone (Madden and Sarathi, 1985;Wu and Fulton, 1971) as the porous media in their laboratory studies of thermal oil recovery processes.…”
