Abstract
The cooling of the geothermal reservoir due to reinjection wuter is serious problem in the maintenance of the geothermul reservoir. A possible to measure the thermal state in the reservoir is a temperature monitoring system utilizing the optical fiber sensor which is available today for high conditions (at degrees C). However, the lifetime optical fiber sensor in geothermal well is not This paper shows our concepts of a temperature profile bottom pressure monitoring system design which uses optical fiber sensor in O.D. capillary und its test results in laboratory and a geothermal well for aperiod of six months.
