Abstract

Fibre-optic seismic sensor systems for permanent monitoring of oil and gas reservoirs have been under development for several years. Such systems, which may comprise over 30 000 sensor channels, require an efficient optical multiplexing architecture. We report test results from a time and wavelength based multiplexing architecture combining up to 256 sensor channels onto a single optical fibre pair, while still allowing low system noise floor and dynamic range over 180 dB.
