Evaluation of Factors of Soil Resistivity in the Niger Delta

Soil conductivity is responsible for its aggressive behavior to metallic objects either in contact or buried the ground. Rapid deterioration and eventual rupture of pipelines leading ultimately crude oil spillages have been economic as well environmental concern. Although many factors contribute soil resistivity, these relationships hardly quantitatively expressed. This paper explores affecting resistivity firstly by matching spatial regional distribution with each identified influence, including ground elevation type, depth water table undrained strength. 183 Vertical Electrical Sounding VES ABEM SAS 1000, using Schlumberger electrode configuration were carried out along a pipeline route generate across linear alignment that traverses three geomorphic sub-environments Niger Delta Region. The apparent values averaged over depths 3 m 10 plotted against co-ordinates Surfer-16 overlaid on Google earth Pro produce enhanced location visibility. results show influenced lower areas shallow occurrence.
