18 Oilfield Review Casing Corrosion Measurement to Extend Asset Life Corrosion challenges are not new to the oil and gas industry, and producers are continually seeking new ways to keep corrosion at bay. Experts have made advances in corrosion monitoring along several fronts. The implementation of these technolo- gies may help operators optimize infrastructure utilization, maximize production and minimize negative impact on the environment.

On the one hand, profitability dictates that producers maximize long-term production while minimizing operating expenditures. On the other hand, environmental compliance requires that companies conduct exploration and production operations safely and in an environmentally responsible manner. > Typical refining-corrosion life cycle for metals. Energy is stored in a metal as it is refined from its naturally occurring state (such as iron ore) to an alloy. Corrosion takes place spontaneously and releases the stored energy, which returns the metal back to a lower energy state. That process can be slowed by the application of one or more field-based mitigation measures.
