oa Rock Properties under CO2 Exposure: Database Compilation from Scientific Publications

Carbon capture and storage (CCS) is a potential storage solution which can aid in working towards net-zero emission targets through preventing CO2 emissions from industrial sources reaching the atmosphere via sequestration in appropriate geological formations. The injection of CO2 into geological reservoirs may lead to negative effects on the injected reservoir and surrounding subsurface. This happens through complex chemical and physical interactions between injected and in-situ fluids, and any suitably reactive minerals within affected formations. There is still much uncertainty in how these are constrained, the complexity, distribution and scale of their impacts, or the kind of timeframe that these effects occur in. Ongoing work has focused on gathering published models, real-world and experimental data that are useful in enabling and validating predictive work. The goal of this being, to generate a look-up tool that will improve predictive models and workflows through the application of relevant input data. The tool provides information on changes in mechanical, hydraulic, chemical, and other material properties, their significance to potential processes, their evolution with time and the uncertainty in our level of current understanding. This resource has been gathered in a single location so that it can be efficiently exploited.
