- Abstract
Electrical resistivity imaging (ERI) is the emerging tool for investigation of subsurface formations by studying the variation in their electrical properties. In the present investigation, the electrical image of a quartz reef has been generated through sounding with the help of 35 electrodes. Seven profiling stations were marked across the quartz reef for generation of ER images. All apparent resistivity data were converted in absolute resistivity of various layers through inverse slope method with the use of surfer software and an ER image was generated to compare it with the real image. Deference between the ER image and the real image (field image) was found negligible. This indicates that sounding data generated though inverse slope method can be utilized as input for generation of the ER image. Image generation using this method is easier, less time-consuming and cost-effective. An equation has been derived for calculating total number of electrodes to be required at desired station or location for performing vertical electrical sounding (VES).
