Characterization of aquifer using Geo-electrical techniques in Kaani, Khana Local Government Area of Rivers State, Nigeria was carried out using Schlumberger electrode configuration of Vertical Electrical Sounding (VES) technique. The field data were obtained using Herojat resistivity meter which was applied on ten VES stations. A maximum distance of 150m and 7m were used for current electrode spacing and potential electrode spacing respectively. Data obtained from the field were analyzed using IPI2WIN computer software. The results reveal resistivity value ranges from 61.7Ωm to 7487Ωm, thickness ranges from 0.883m to 55.85m and depth value ranges from 0.883m to 105m which implies that the study area has a shallow aquifer and moderate thickness with potential for groundwater exploration. The results also reveal seven curve types KK, AH, HK, KKH, HK, QKK and QKAK in the study area. The results from the study area will be useful in well construction to reduce the high level of borehole failure and groundwater contamination due to high longitudinal conductance value of the aquifer in the study area.
