Paper presented at the ISRM International Symposium - 8th Asian Rock Mechanics Symposium, October 14–16, 2014
Paper Number: ISRM-ARMS8-2014-190
... Abstract A method is proposed for a time-lapse study of Carbon dioxide Capture and Storage (CCS) and Enhanced Oil Recovery (EOR) using the seismic Accurately Controlled and Routinely Operated Signal System (ACROSS) and seismometer array. However, it is considered that near-surface effects...

... seismometers do not indicate distinct surface wave arrivals. We calculated transfer functions from the fixed source at A or B to all 126 seismic stations buried at 30 m and two borehole seismometers at 70 m and 200 m. The temporal changes in the original transfer functions were not distinct. If we look the 12...

... of the ground surface. The observation work of this exploration is only limited to observing the natural microtremor of ground surface by a few number of seismometers. No large scale instrument is necessary. These facts make the exploration method simple, easy and non-destructive. This exploration method can...
