摘要：

A new downhole measurement technique has been proposed based on optical fiber Bragg grating (FBG) sensors for long-term monitoring of strain and its corresponding stress build-up in geological fault zones. Design and development of the present downhole sensor installation equipment have been demonstrated. Results from laboratory tests and from first field experiments in a research borehole at Trizonia island in the Gulf of Corinth area (Greece) have been reported.
