Control and management of corrosion have always been the concern of oil and gas asset management due to the chal- lenging outcomes of failed facilities that lead to environmental pollution. Corrosion has an impact on human safety, environmental safety, and productivity. There are various ways of identifying environmental corrosivity, but there is no distinct map or relation for suggesting the corrosion severity of such an environment. This research aims to create a cor- rosion map using MATLAB for Rivers State, a mega oil-producing state in the Niger Delta, based on soil resistivity and pH across. The pilot test conducted using 40-point soil pH and resistivity data suggested that it is feasible to develop a unique corrosivity map for a region since the result showed an R-square value of 70.03%. However, possible constraints of the mapping process were discussed, as well as suggestions for a wider survey and improvement.
