Effective monitoring of the carbon dioxide storage is essential to ensure safe containment of the CO2 plume in the reservoir. Currently geophysical monitoring usually involves a combination of various s eismic surveys acquired using a large array of seismic receivers and moveable sources to image the emplaced gas plume. Deployment of equipment for such surveys usually takes a long time which becomes expensive. At the CO2CRC Otway Research Facility we are exploring the use of distributed acoustic sensing (DAS) combined with permanent surface orbital vibrators (SOVs) in order to build a permanent seismic monitoring array that is able to image the development of the plume in real time. In this study, we acquire a series of VSP trials to test performance of DAS in combination of SOV sources. The objective was to test different fibre types and different sweep parameters. The results of the field trials show that DAS/SOV configuration present good quality VSP datasets, imaging beyond the injection interval when using a more powerful motor with sweeps from 0 to 80 Hz.
