Sixteen vertical electrical soundings (VES) were carried out at Ughelli, Nigeria in order to ascertain the groundwater potentials of the area. The instrument used was the ABEM Terrameter SAS 300B, employing the Schlumberger electrode configuration. Interpretation of the VES data by computer aided modelling showed that the subsurface structure can best be described in terms of three or four geoelectric layers. The first layer showed resistivity range of 14.0 - 763.2Ωm and thickness range of 0.5 - 5.4m. The resistivity of the second layer ranged from 102.7 - 4806.7Ωm while the thickness is in the range of 1.3 - 20.0m.The third layer showed resistivity range of 421.7 - 2237.4Ωm and thickness range of 9.1 - 48.0m. The resistivity of the fourth layer varied from 291.7 - 1728.5Ωm. The aquifer thickness was variable, ranging from 14.3m up to a maximum of 48.0m, around Afiesere area in the eastern part of the study area. The longitudinal conductance of the aquiferous layers varied from 0.005mho up to a maximum of 0.110mho, also at the eastern part of the study area. This portion of the study area promises high potentials for productive borehole development programme in Ughelli.
