Project Description

This project developed a comprehensive analysis of programmatic and technical risks associated with CO2 storage in deep brine reservoirs. The study quantified the risks associated with CO2 storage projects by: (1) employing Bayesian inference to evaluate storage risks; (2) utilizing the safety record of the CO2 based enhanced oil recovery industry (CO2-EOR) and pilot storage projects to identify and evaluate potential risks; (3) developing and quantifying the nature of programmatic risks; (4) utilizing diverse, highly qualified expert panels drawn from industry and nongovernmental organizations (NGO) to evaluate changing perceptions of programmatic risks; and (5) assessing the possible consequences to water ecology and energy resources from potential leakage of CO2 from deep brine reservoirs.

Project Benefits

This project focused on developing an improved risk assessment framework for geological storage of CO2. Improved risk assessment methods allow project developers to more confidently ensure that the CO2 is permanently stored. Improved risk assessment technologies contribute to better storage technologies that help reduce CO2 emissions to the atmosphere. Specifically, this project used Bayesian inference methods, safety records from analogue projects, expert panels, and technical studies of pressure impacts and potential CO2 release to develop a comprehensive analysis of programmatic and technical risks associated with CO2 storage in deep saline formations.
