Oil spill occurrence during exploration, production and distribution can causedeleterious impact on the environment. Contamination of local streams-rivers, farmlands,forest resources and biodiversity in oil producing areas presents strong significantpossibility of significant harm to human health. Geo-information technologies presentnew opportunities for assessing stress environment and ways of determining exposuresusceptibility in such areas. The study assesses the geographical distribution ofoil-spills cluster and pattern using three geospatial techniques with ground dataat 443 oil-spill incident sites from 1985-2008. The places with high high-volume-large impact-close proximity to communities and low incident low-volume-less impact-far-distanceare related to the quantity of oil-spills identified within those communities consideredsusceptible to spill impact and possible exposure. While the average nearest neighborhoodanalysis showed a probability that oil-spill distribution in the area is clusteredratio < 1 with index value 0.19, the Getis-Ord General G test indicated thatthe oil-spill with high quantities volume discharge are significantly clusteredwithin every 400 m. The Moran’s I indexindicted that there is
