The paper reports the change in groundwater level observed in 30 wells in ten locations in southern Nigeria. Borehole data confirmed the electrical resistivity soundings which indicated the presence of topsoil, medium sand, ...

An integrated approach for the estimation of volume of shale from a suite of logs comprising the gamma ray, neutron-density combination, resistivity, combination of different methods (total) was carried in an Old Niger ...

Seismic refraction shooting and Electrical resistivity depth sounding have been carried out at Igbogbo (Ikorodu area, Southwest Nigeria) to determine the structural setting of the subsurface materials and groundwater ...
