Corrosion Control in Oil & Gas Exploration Industry



The annual losses due to corrosion and the cost of rectification run to several billion dollars in oil & gas exploration industries worldwide. High production under aggressive and extreme operational conditions necessitates developing new materials with peculiar failure behaviors. Thus the industry operators are on continuous perusal with different corrosion management strategies. Yet unforeseen failures of top-side, sub-surface, and sub-sea infrastructure due to corrosion not only entail the loss of production but the loss of life as well. Prediction of failure behaviors, remaining useful life, and corrosion preventive measures are all approaches in corrosion management for the safe and economic operation of production wells and other facilities. Successful corrosion management influences the financial outcome of the company by ensuring the cost-effective selection of materials, chemical treatments, coatings, cathodic protection systems, and appropriate designs
