Utilizing Electrical Resistance (ER) Probes for Corrosion Rate Monitoring, Inhibitor Performance Evaluation, and Chemical Product Selection

Electrical Resistance (ER) probes offer a continuous, high-resolution method for measuring corrosion rates in oilfield systems. This study demonstrates how ER data can be used to establish baseline corrosion, evaluate corrosion inhibitor performance, and guide product selection under varying produced-water and multiphase conditions. Results show that ER data can quickly distinguish between inhibitor chemistries, quantify treatment effectiveness in a short period, and guide the selection of the most effective corrosion control products for specific fluid chemistries and operating conditions. Overall, ER probes proved to be a practical and sensitive tool for corrosion inhibitor performance verification and product selection, supporting more efficient chemical programs and stronger asset integrity management.
