Review of laboratory-scale geochemical and geomechanical experiments simulating geosequestration of CO2 in sandstone, and associated modelling studies

The main knowledge gaps addressed in this project are the lack of integrated studies assessing both the geochemical and associated geomechanical changes to reservoir and seal rocks with CO2 injection. This initial literature review details the current knowledge and describes commonly used laboratory approaches to assessing reactive geochemical interactions of CO2, formation water and the rock framework. It provides a thorough comparison of the results for both laboratory and modelling experiments documented in the literature.  This is the backdrop of the proposed research on coupled reactive geochemistry and geomechanics in Australian geological scenarios for carbon storage.
