The log signature of the logstratigraphical units was expanded to also include the formation resistivity and the sonic velocity by Schovsbo et al.
It allows imaging groundwater salinity with relatively high spatial resolution, since formation resistivity as determined ERT strongly depends on groundwater salinity.
In the past twenty years, many authors presented induction tools comparing the apparent resistivity achieved at several hundred kHz and 2 MHz for detection of porous formation resistivity dispersion [11,12].

of Oklahoma) and Donaldson (retired after a long career in public, private, and academic spheres) introduce mineralogy and petroleum geology before covering porosity and permeability, formation resistivity and water saturation, capillary pressure, wettability, applications of Darcy's Law, naturally fractured reservoirs, and the effect of stress on reservoir rock properties, among other topics.
