Abstract

Corrosion control in pipelines and wells is a critical issue in the oil industry. In this paper, we present an optical fiber sensing technique devoted to monitor one of the parameters involved in corrosion: the environment acidity. In the proposed technique, a transducer mechanically couples a fiber Bragg grating to a pH sensitive hydrogel. The possibility of determining pH values with resolution of 10^-2 in a range from 3 to 6 is evaluated and discussed.
