The research was carried out in Lucas do Rio Verde city, Mato Grosso State, Brazil, to estimate the depth and thickness of hydrogeological units. This parameter was estimated using vertical electrical sounding (VES), with AB/2 maximum of 2000 m. The results show that the average depth and thickness of Utiariti aquifer are respectively 13 m and 90 m, the Saltos das Nuvens Formation has average depth of 103 m and thickness greater than 600 m. Only the portion of the Utiariti aquifer consisted essentially of fine to medium sandstone was defined very precisely by the VESs. Geological data from the well, used in the interpretation of VES allowed greater reliability on the obtained results.
