Dynamic Risk Assessment for Geologic CO2 Sequestration

At a geologic CO2 sequestration (GCS) site, uncertainty usually leads to large in the predictions of properties that influence leakage risk such as saturations and pressures potentially leaky wellbores, CO2/brine rates, metrics impacts on drinking water quality groundwater aquifers (e.g., sizes pH total dissolved solids (TDS) plumes aquifer). The these risk-related system can substantially affect decisions related safe operations management GCS sites. objective this study is develop novel approach based dynamic assessment effectively reduce predicted metrics. proposed workflow for was demonstrated with synthetic field case Rock Springs Uplift (RSU) site southwestern Wyoming, USA. It observed NRAP-Open-IAM tool coupled conformance evaluation be used quantify reduction GCS.
