Iso-resistivity/Spatial distribution maps represent the connection between equal electrical apparent resistivities
which in turn confirms two-dimensional lateral variations in subsurface lithologies.
at an adsorption equilibrium pressure of 0.534 MPa for continuous adsorption and for isovolumetric adsorption are compared in Figure 7, which shows the resistivity changes for the two adsorption methods for the same gas content, for eight isovolumetric gas injection stages.
Some anomalous zones of low electrical resistivity extending below the bottoms of wells CV-4, CV-5, and CV-6 exhibit similar electrical resistivities
to those associated with the high quality lithium brine near the bottom of well CV-8.
This method employs a plot of the sum of the apparent resistivities
([SIGMA][[rho].sub.a]) versus depth.

The interpretation of the VES sounding curve realized close to the borehole indicates that the geoelectric section is composed of six layers: (1) the first three thin near surface layers have high resistivities
ranging from 58 to 372 ohm-m and a total thickness of 7.5 m that correspond to top soil and dry alluviums; (2) the 42 m thick fourth layer has an intermediate resistivity of 19 ohm-m and is composed of alluvium; (3) the fifth layer has a relatively high resistivity of 47 ohm-m and also is an aquifer; and (4) the sixth and bottom layer is the conductive geoelectric basement with an average resistivity of 12 ohm-m that is composed mainly of clays.
The three principal resistivities
of the half-space are [[rho].sub.x] = [[rho].sup.y ] = 0.5 [OMEGA] x m and [[rho].sub.z]= 2.0 [OMEGA] x m.
The resistivity results show that, for all the soil-cement samples, at freshly prepared state and after one hour of curing time, resistivities
are high when compacted on dry side of optimum.
In addition, to evaluate the average effect of fibrous radius R, the static flow resistivities
with different fibrous radii are calculated.
Carbon black-filled polymers are used for materials with specific resistivities
ranging from 10 to 1018 ohm-cm.
The main purposes of quantitative interpretation of VES are to determine the thickness of the different formations having different resistivities
However, a distinct difference was observed between their electrical resistivities
at room temperature, as shown in Fig.
