Corrosion and related issues are a major contributor in failures of electrical submersible pumps (ESP). This paper describes the development and preliminary testing of a new downhole corrosion sensor to be integrated into ESPs for providing continuous monitoring. We will describe the development of a downhole sensor, testing and applications of such a sensor. In-situ corrosion monitoring provides valuable and actionable data that enables implementation of mitigation strategies before damages occur and allow for planned servicing. It ultimately allows operators to make informed decisions on corrosion control and ESP maintenance scheduling.
