An extensive, computer-based coupon program has been used to monitor corrosion since production began in the eastern half of Prudhoe Bay’s oil field, operated by ARCO Alaska, Inc.1 In situations where severe corrosion has been identified or where corrosion inhibitor performance is evaluated, the coupons are supplemented with electric resistance (ER) probes. The number of ER probes used has been significantly expanded as corrosion becomes worse and large inhibition programs are implemented.

Widespread use of ER probes over a large area has been possible by utilizing automated systems. However, permanent installation of continuously-monitored electrical devices in hazardous areas has been difficult. Details of the problems encountered and solutions developed will be discussed. Furthermore, the quality of data derived and the usefulness of information provided by ER probes will be addressed.
