Schlumberger Sounding Results near Twin Falls, Idaho.
by
Robert J. Bisdorf
INTRODUCTION
The U.S. Geological Survey has nade 85 Schlunberger soundings near Twin Falls, Idaho since 1982. These soundings were nade in support of the Water Rescouces Division Regional Aquifer-Systens Analysis study. The soundings were nade to estinate the thickness of the basalt, which is the nain aquifer in this area.
The surveyed area is nostly in the Snake River Plain and is conposed prinarily of Quaternary basalt. Interflow zones of cinders and rubble nake for high porosity and high hydraulic conductivity (Whitehead and Lindholro, 1985). Tertiary aged Banbury Basalt of the Idaho Group (Covington, 1976) is exposed in the wall of the Snake River canyon and probably underlies the Quaternary basalt in the study area.
The purpose of this report is to release the observed Schlunberger sounding data. An automatic interpretation of the soundings is also given.
SCHLUMBERGER SOUNDINGS
Figure 1 is a nap showing the location and identifying nunber of the 85 Schlunberger soundings. The soundings are labeled 1 thru 59 and 101 thru 126. The soundings were autonatically processed and interpreted as a series of horizontal layers using a conputer progran written by Zohdy (1973). Some soundings were distorted due to the effects of cultural conditions such as netal fences, grounded power-lines, and buried telephone cables. When possible the distorted soundings were snoothed to give a sounding that could be interpreted. Some soundings were too distorted to snooth. The individual sounding interpretations are given in the appendix. For each sounding the data in the appendix include:
1) A log-log plot of the field data points where the "0"'s represent the individual data points. Data points neasured with the sane potential electrode spacing are connected with a solid line. The current electrode half spacings (AB/2), which were neasured in feet, have been converted to neters.
2) A tabulation of the AB/2 spacings in neters and the corresponding apparent resistivities in ohn-ro.
3) A log-log which:
plot of the output of the automatic inversion program in
a) The continuous curve represents the shifted-digitized field curve obtained by shifting the segments of the field curve to produce a continuous curve and digitizing the shifted-curve at the rate of six points per log-cycle.
b) The step-function curve represents the distribution of interpreted resistivity with depth (interpreted model).
c) The plus (+) symbols represent points on a theorectical curve calculated from the interpreted model. These data are plotted to show how well the model represents the shifted-digitized data.
4> A tabulation of the interpreted depths in meters and the interpreted resistivities in ohm-m. The last layer depth is an arbitrarlily large number and is intented to represent an infinite depth.
Soundings that were manually smoothed are indicated by a "-S" appended to the title on the plot of the interpretation (item 3 above). Although sounding 10 was affected by a metal fence, the data show none of the symptoms of cultural problems, in fact the sounding looks good. The only indication that something is wrong is that this sounding indicates a different resistivity section than that indicated by nearby soundings. To verify that the curve was distorted, sounding II was made about 400 m to the south, away from any possible cultural influences. The two soundings are similar to an AB/2 spacing of about 180 m, then sounding 10 starts to rise, indicating a more resistive structure, while sounding II is descending slightly, indicating a somewhat more conductive structure.
The USGS drilled a test hole near soundings 47 and 16 to verify the interpretation of the Schlumberger sounding data and to make various hydraulic tests (Whitehead and Lindholm, 1985). The automatic interpretation of sounding 47 and the lithologic interpretation from the test well have similar features but depths from the sounding interpretation are deeper. Depths from the lithologic interpretation were used with a guess and reguess interpretation scheme in order to develop a resistivity model that would fit the lithologic model observed in the test well as well as the original sounding data. Figure 2 shows the original resistivity model, the resistivity model using the test well depths and the lithologic model. A sounding curve calculated from the resistivity model that used the test well depths, fits the sounding data as accurately as the original resistivity model. The 2 resistivity models are an example of equivalence (Zohdy and others, 1974, Bisdorf, 1985).
SUMMARY
Although the interpretation of sounding 47 resulted in depths deeper than those observed in the test well, the sounding did detect

the presence of a low resistivity layer beneath the surface basalt.Using the results of the test well and a different interpretationscheme it will be possible to generate more accurate resistivitymodels for the other soundings.
