Real time triaxial resistivity and pore pressure penetration measurements for monitoring saturation and electrical property alterations under stress
The use of Archie's equation relating water saturation in clean sandstone formations to the electrical resistivity of the formations and the fluid properties has been key in electrical log interpretation. Archie's equation has been widely used for most sedimentary rocks for fluid saturation evaluation since its first application in sandstones. Recent studies have shown that Archie's equation is not an accurate representation of the electrical property representation in all formations (Herrick et al. 2001; Kennedy et al. 2012; Suman et al. 1997; Moran et al. 1979; Mahmood et al. 1991; Kennedy ...
