1 Resistivity modeling

2 ELECTRODE ARRAYS Pole – pole Pole - dipole Dipole - dipole Wenner
Schlumberger 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.
