Effect soil resistivity in mapping potential corrosion in underground pipelines area

The research has been conducted to map potential corrosion in underground pipeline using Kriging interpolation method. The project area is located in North Aceh, Indonesia between latitudes 5°11’N and 5°15’N, and longitude 96°48’E and 97°03’E. The measuring of corrosion potential for underground piping installation lines has been done with Wenner method. The result of this measurement is interpolated by Kriging method to obtain the mapping. The results show the distribution of various resistivity values with varying contours based on depth measurement. From the inversion data onto res2dinv software, images that have different colors are obtained. Each color represents different resistivity values that make up some irregular layers. In conclusion, the site of the study was potentially mildly corrosive, corrosive and highly corrosive.
