Abstract

A new emerging technology is the Distributed Acoustic Sensing (DAS) or Distributed Vibration Sensing (DVS) whose principle is to use the optical fiber as a sensor to measure the acoustic field every meter over the entire length of the fiber. The Rousse-1 well located south-west of France, currently an injector well for a CO2 storage pilot and equipped with a fiber for optical P/T gauges, was selected for a DVS field trial, simultaneously with a micro-seismic calibration campaign. Although the fiber was clamped on tubing, compressional direct arrivals could be detected down to 4 km depth, with source-wellhead distances ranging from the wellhead to 2 km. The optical fiber could become the next generation technology for cost-effective, complete coverage of reservoir monitoring and there is significant scope for further improvement in both operational and data quality.
