Fibre optic Distributed Acoustic Sensing (DAS) or Distributed Vibration Sensing (DVS) is a technology that uses an optical fibre cable as a sensor for acoustic signals. Within the last years, DAS/DVS was further developed to record seismic data. We present a successful DAS/DVS-VSP (Vertical Seismic Profiling) field test performed at the Ketzin CO2 storage site, Germany. It was possible to record 23 VSP source points simultaneously within four wells and to build a small 3D VSP cube. The DAS/DVS-VSP cube complements the 3D surface seismic by providing a focused high resolution image below the injection site.
