Abstract
Summary
The project SRD3.3 is focused on the prediction and verification of shallow CO2 migration, associated with a controlled release of carbon dioxide within a near surface fault. The project aims to gain a better understanding of CO2 leakage in shallow faults in sedimentary basins and establish reliable imaging methodology of the CO2 migration behaviour. The project’s program for the near surface characterisation and monitoring strategies is focused around borehole seismic methods. The program is complemented with a trial of the cross-hole seismic approach. The paper presents and describes the results of the cross-hole data analysis in application to monitoring the shallow CO2 injections.
