Body-wave seismic interferometry on passive seismic data for imaging CO2 reinjection at the Hellisheiði geothermal power plant, Iceland
CO2 and H2S are reinjected at Hellisheiði, Iceland, to reduce the emissions of greenhouse gases. An active-source seismic campaign was done in July, 2021, to image the reinjection reservoir with various seismic methods for consecutive monitoring. At the same time, passive-source seismic data was rec...
