MONITORING A REGION OF INTEREST IN A SUBSURFACE FORMATION |
摘要 |
A method of monitoring a subsurface formation including a region of interest below a surface region, which method comprises the steps of exciting seismic interface waves in the surface region over an area of the earth's surface at a first and a second moment in time; detecting seismic interface waves signals for a plurality of locations in the area; determining, from the detected seismic interface wave signals, an areal distribution of a parameter related to seismic interface wave velocity change between the first and second moments in time; and inferring, from the areal distribution, an indication of a volume change of the region of interest between the first and second moments in time. |
