Abstract

Soil corrosion poses a significant threat to buried pipelines’ integrity and reliability. This study uses electrical resistivity mapping to assess soil corrosivity along the Eket-Port Harcourt pipeline route, identifying high-risk areas based on soil resistivity, moisture, and chemical composition. Field investigations, including resistivity surveys, soil sampling, and environmental monitoring, created spatial maps of corrosion risk zones, correlating soil characteristics with corrosion rates. Key findings show low resistivity correlates with high corrosion potential, revealing hotspots for targeted maintenance and mitigation. The study highlights electrical resistivity mapping as an effective tool for proactive soil corrosivity assessment and pipeline integrity management.
