Authigenic carbonates as natural analogues of mineralisation trapping in CO2 sequestration: a desktop study

9th August 2013

Topic(s): Carbon capture use and storage (CCUS), CO2 storage

This project is aimed at supporting CO2 storage projects in Australian sedimentary basins through investigation of the controls on carbonate authigenesis in freshwater aquifers as a natural analogue for mineralisation trapping. The literature review and desktop study provide a foundation that synthesises what is known about the controls on carbonate precipitation in aquifers with different chemistries, reservoir temperatures and available volumes of CO2. The parameters derived from this study will feed into simulations of engineered mineral trapping of injected CO2 that will then be tested experimentally in the laboratory with Precipice and Hutton sandstone core samples.
