ELECTRODE ARRAYS

3. Data plotting

4. CHOICE OF THE “BEST” ARRAY
Depends on:
type of structure to be mapped
sensitivity of the resistivity meter
background noise level
Things to be considered:
depth of investigation
sensitivity of the array to vertical and horizontal structures
horizontal data coverage
signal strength.
