Evaluation of long-term stability of caprock sealing under deep saline CO2 sequestration environment

posted on 2021-08-05, 03:17 authored by DINESHA WANIGARATHNA JAYASEKARA
CO2 sequestration in deep saline aquifers plays a vital role in reducing the atmospheric concentrations of anthropogenic CO2. The performance of caprock in deep saline aquifers is significant to reduce the risk of CO2 leakage into the fresh underground waterbodies. The aim of this study is therefore to obtain comprehensive knowledge of short- and long-term caprock integrity in deep saline CO2 sequestration environments. For that, the thesis includes advanced experimental and geochemical modeling analyses to reveal the chemical-hydro-mechanical behaviour of caprock due to CO2 sequestration.
