| Abstract | We analyzed the ACROSS - DAS VSP baseline data with offsets to ~770 m acquired in the Aquistore CO2 storage site in Canada to demonstrate its potential for permanent reservoir monitoring (PRM). The data
was recorded for 8 hours. Stacking data improved S/N in accordance with the square root of the stacking number. The data quality was comparable with dynamite -DAS VSP data in the same field. Reservoir reflectors at ~3250 m depth between the source
and the DAS well were imaged by applying reverse time migration (RTM). The resulting image has high correlation with a synthetic seismogram at the injection well ~150 m away from the DAS well. These results demonstrate the high potential of ACROSS -
DAS combination in permanent reservoir monitoring to continuously monitor small changes in seismic properties in the reservoir. |
