A methodology for the interpretation of aquifer tests: Application to CO2 residual trapping experiments at the Heletz site

Estimation of trapped CO2 is essential for assessing the potential of a site for geological carbon storage. In situ residual trapping can be obtained through Residual Trapping Experiments (RTE). RTE experiments consist in performing characterization tests e.g. hydraulic, thermal and tracer tests before and after creating the residually trapped zone of CO2 and estimating residual saturation from the differences between the two tests. We introduce...
