Characterization of formation properties for geological storage of CO 2 – Experiences from the Heletz CO 2 injection site and other example sites from the EU FP7 project MUSTANG

Residual or capillary trapping is one of the key trapping mechanisms for CO2 geological storage. At the Heletz, Israel, pilot injection site, two dedicated field experiments have been carried out to characterize it in-situ. This paper presents the model analyses of the second of these tests, the Residual Trapping Experiment II (RTE II). In the experiment hydraulic, tracer and thermal tests before and after the generation of the residually...
