Abstract
The need for safe CO2 storage sites is accelerating and so is the demand for improved methods to assess and manage the geological risks at proposed sites. The SHARP project has worked specifically with the uncertainties in all parts of the geological containment risk evaluation process, from uncertainties on input parameters to uncertainties on methods and models to the risk assessment combining all elements. The SHARP methodologies integrate models of subsurface stress, rock mechanical failure and seismicity to provide efficient CO2 subsurface risk monitoring and management. The knowledge within each of the geoscientific disciplines has been investigated and advanced while maintaining a close dialogue to optimize integration of results across disciplines. Quantitative results from laboratory experiments on rock strain and failure together with stress data from the integrated earthquake catalogue and regional scale tectonic and deglaciation models have provided input to basin-scale geomechanical models. An ensemble of geomechanical models within the realistic bounds of variability has served as input to Monte Carlo runs to assess the quantitative containment risk. The quantitative risk models can serve as input to smarter monitoring by identifying areas where monitoring is needed the most, thus providing an early warning should unexpected deviations occur.
A multi-disciplinary workshop was held September 17th-18th, 2024 to evaluate the results from the different SHARP Work Packages and discuss the lessons learned by combining these results for a full chain of geological containment risk evaluation. The theme of the first day of the workshop was “Geological risks and triggers”, and the theme of the second day was “Recommended input to quantitative containment risk guidelines”. This report sums up the main points.
