Abstract
The method employed was an electrical resistivity survey which was carried out to study the subsurface layer with a view of determine the depth of potential aquifers, the thickness of an aquifer, and to determine the potential aquifer for groundwater exploration. Using the Schlumberger array technique, Vertical Electric Sounding (VES), along with Self Potential well logging was carried out at six (6) VES stations in Amaigbo using the ABEM SAS 1000 terrameter and ABEM SAS 1000 logger respectively. The field data obtained have been analysed using the computer software (IP2win) which automatically interprets the apparent resistivity. The VES result revealed the heterogeneous nature of the subsurface geological sequence. Result from the Geo-electric section showed that the aquifer resistivity of the study ranges from 352\(\Omega\)\(\mathit{m}\) to 7514\(\Omega\)\(\mathit{m}\) , with potential groundwater depths ranging from 45m to 119m which shows that the study area is perfect for groundwater development. The data from the SP well logs correspond to the VES data obtained.
