Abstract

Summary

There is a growing interest in the application of Distributed Acoustic Sensor (DAS) for permanent reservoir monitoring. The optical fiber cables installed along the borehole allow for continuous recoding of 3D seismic surveys. We report on a simultaneous acquisition of distributed acoustic seismic surveys with pre-installed single-mode and multi-mode optical fiber cables at Aquistore and compare the results with 3C geophones. The advantages of precise time lapse measurements using the DAS system for the long term evolution of CO2 distribution will be also discussed. Furthermore, the use of multi-mode optical fiber cables marks a significant potential of the DAS system used in this project which opens up the possibility of using existing multimode optical fibers used with the Distributed Temperature Sensor (DTS) for seismic data acquisition.
