Schlumberger - Opis:
- A geophysical survey of basement complex using electrical resistivity method was carried out so as to provide geological and geophysical information on the different subsurface features. The sought-for parameters include thickness, depth, basement for groundwater potential and aquifer protective capacity. The acquired data were process using Win-Resist software and surfer 8, and the result was then analyzed and interpreted. Accordingly, 3-4 geoelectrical layers within the subsurface delineate the area: top soil, lateritic layer, weathered/fractured layer and fresh rock. Resistivity values of the top soil range between 55.5 mΩ to 749.7 mΩ, with average thickness of 0.4 m to 3.6 m, while the lateritic layer ranges between 153.3 mΩ to 862.0 mΩ, with average thickness of 4.5 m to 20.7 m, the weathered/fractured layer in turn ranges between 15.6 mΩ to 698.9 mΩ, with average thickness of 7.7 m to 55.2 m, and the fresh rock ranges between 13.4 mΩ to 5102 mΩ, with infinite homogeneous half space. Over all, the longitudinal conductance of the overburden units range from 0.147 mhos to 0.957 mhos and the overburden is thick enough for groundwater exploration activities. The results provide reasonably information that the aquifer units are weathered/fractured layers with a significant groundwater potential that is free of contamination.
