Abstract

During the past four years, Optoplan/Weatherford have developed and qualified high responsivity high bandwidth fiber interferometric sensors, FBG based fiber networks and a high resolution electro-optic instrumentation system for high temperature and high pressure in-well seismic imaging and monitoring applications. During this period, several field trials have been conducted, and recently a six level, three component (3-C) accelerometer system was installed permanently in a well at a gas storage field for TotalFinaElf in southwestern France. Results obtained from qualification and field testing of the sensors, network and instrumentation system are presented.
