Delineation of Subsurface Migration Pathways of Petroleum Contaminants in Ikarama, Okordia Clan of Bayelsa State, Nigeria

One well-known cause of groundwater contamination in developing nations that produce oil is oil leaks. Oil leaks are typically caused by a variety of circumstances, such as inadequate management and upkeep of oil facilities, equipment failure, and pipeline vandalism by oil criminals. This research evaluates the movement of underground oil contaminants in an oil production field at the Okordia clan's Ikarama hamlet in the Yenagoa Local Government Area in the state of Bayelsa. Schlumberger array was utilized in order to apply the electrical resistivity tomography technique along three (3) VES surrounding the oil spill spot. Values for resistivity were found. In the locations under study, three (3) vertical electrical soundings (VES) were conducted. Comparison of theoretical soil resistivity to measured fluid resistivity for various caption exchange Values of capacity have been researched. The resistivity values, when reversed, ranged from 0.17 m to 146.8 m. The hydrocarbon contamination (oil plumes) is the cause of the high resistivity values (21.54 – 146.8 Ωm) and the low resistivity values (0.1–15.8 Ωm). The 2D resistivity approach is an effective tool for examining pollution caused by hydrocarbon in a coastal environment, as this study has proven.
