Application of Electrical Resistivity Method for the Investigation of Shales in Dange Area, Northwestern Nigeria
Click to downloadAbstract
Field geology of Vertical electrical sounding (VES) using the Schlumberger electrode configuration was employed for geophysical investigation of shales in Dange area, northwestern Nigeria. The aim was to define the depth to the top of the shale unit, its thickness and lateral extent. Twenty- three VES points were located and fully occupied within the study area. The results of the investigation show a system of three geo-electric layers for 16 VES stations while the remaining 7 VES points show a system of four geo-electric layers. The VES curves were classified into 14 HA, 1K, 2KH, 4QH and 2HA types. The resistivities of the shale unit range from 3 to7 Om while the thicknesses range from 4.1 to 40.7m. showing wide lateral.
