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.
