Abstract: Purpose: Oil pollution started as a cause of oil business in Nigeria that demonstrates political and economic undertone. Oil spills occurred during exploration, production and distribution of petroleum products, and created environmental impact. The nature of the business has indirect implicitness on the soil, water and the entire ecology as a whole. The aim of the paper was to analyse oil spill Geospatially and its objective was to discuss the causes, modelling and the sources of oil spill. Methodology: The materials used were cover ArcGIS 10.7, MS word, ENVI 4.5 and Landsat imagery of 2019 and the methodology involved image classification, vectorization, and spatial analysis. Findings: The study found out that illegal bunkering site are the causes of the spill, Asari-Toru reported 3, Delga 5 and Akulga 1. The study evaluated the impact level against thirty-four communities, Buguma, Tombia, Sama, Krakrama, Idama and Bille are placed under very high impacted state from (0.111m2 - 0.133m2). Following the stratification of the impacted result, Ido, Abalama, Opurobokokiri, Ifoko and Sangama are recorded against high area (0.083m2 -0.111m2). The mapping showed that the spread of oil spill cover 79416.180ha against 24.976% from the classification scheme. Conclusion: Satellite imageries have demonstrated the effectiveness of satellite-based mapping over the earth activity, especially oil pollution in the selected Local Government Area of Rivers State, Nigeria. Recommendation: The study recommended that Oil bunkers should stop the bunkering, and oil companies should set up vigilante group to monitoring the network of pipelines.
