<p>A METHOD USED IN ELECTRICAL INVESTIGATION OF GEOLOGICAL FORMATIONS SURROUNDING A BOREHOLE COMPRISING: DETERMINING (S1) A GRID OF ISO-PARAMETER LINES (GR) IN A TWO-DIMENSIONAL PLANE, THE PARAMETER BEING AN ELECTRICAL PARAMETER CHARACTERIZING THE GEOLOGICAL FORMATION, INJECTING IN A LOCALIZED MANNER A SURVEY CURRENT IS INTO A SELECTED ZONE (SZ) OF THE GEOLOGICAL FORMATIONS (GF) SURROUNDING THE BOREHOLE (BH), AND MEASURING (S2) A MEASURED VALUE OF A QUANTITY CHARACTERIZING THE ELECTRICAL PARAMETER OF THE SELECTED ZONE BASED ON THE SURVEY CURRENT, AND INTERPOLATING (S3) AN INTERPOLATED ELECTRICAL PARAMETER VALUE OF THE SELECTED ZONE (SZ) BASED ON THE MEASURED VALUE AND THE GRID OF ISO-PARAMETER LINES (GR).
