We have initiated a program for developing and field testing fiber-optics-based sensors to monitor /ital in/ /ital situ/ physical and chemical parameters in highly corrosive environments, such as geothermal wells, oil wells, and hot-water boiler reactors. Inability to sample hot geothermal wells or to measure the chemical composition of hot brines limits our understanding of /ital in/ /ital situ/ conditions in geothermal fields. In this communication, we report preliminary results obtained with a temperature optrode to profile the temperature in a geothermal steam well. To our best knowledge, this is the first time /ital in/ /ital situ/ geothermal well measurements have been made with the use of a fiber-optic sensor.
