Efficacy of Magnetotelluric Method in Delineating Structural Traps Hosting Groundwater Bodies

Abstract

The objectives of this study are to delimit the lateral extent, thickness and depth extent of the overburden or regolith using geophysical methods; and to determine the depth to possible structural traps hosting groundwater bodies or aquifer and fractured zone and drill depth present within the studied area. The Rock Strength Analysis, Water Quantum, Water Quality, Salinity, permeability Factor and GPS coordinates, number of structural trap/fracture sources, and Total drill depth (BHD), all in percentage, were estimated. The magnetotelluric (MT) method was deployed to infer the conductivity of the subsurface geology and as an effective tool for prospecting for groundwater potential. Geophinex, as an automatic groundwater detector, is based on the electromagnetic field principle and thus was carried out across the suspected and known strike of the conductive zone.
