Preliminary Seismic Time-lapse Results from the First Post-injection Survey at the Ketzin Pilot Site
2016 (English)Conference paper, Abstract (Refereed)
Since the CO2SINK project start in April 2004, different methods involving seismics, geoelectrics andpressure-temperature monitoring have been applied at the Ketzin pilot site to map geological structuresand assess CO2 distribution and movement. One 3D baseline seismic survey prior to CO2 injection andtwo 3D repeat seismic surveys during CO2 injection have proven that the 3D time-lapse surface seismicmethod is an effective tool for providing good quality images of the CO2 plume. In the autumn of 2015, athird 3D repeat seismic survey, serving as the first post-injection survey, was acquired. The preliminaryresults show that the predominant westward trend of the CO2 migration is in agreement with the previousresults. No CO2 migration upwards through the caprock was detected. The decrease in the size of CO2plume may be related to ongoing dissolution into the saline formation water.
