National Risk Assessment Partnership (NRAP) Testing and Validation: Part 1 NRAP Open-Source Integrated Assessment Model (Open-IAM)

The Energy & Environmental Research Center tested and validated the National Risk Assessment Partnership (NRAP) Open-source Integrated Assessment Model (Open-IAM). This report presents the results of these efforts, which were conducted under Subtask 3.2 (NRAP Validation) of Task 3 (Data Collection, Sharing, and Analysis) of the Plains CO₂ Reduction Partnership Initiative to Accelerate Carbon Capture, Utilization, and Storage Deployment (hereafter "PCOR Partnership Initiative"). This report provides step-by-step instructions and input files for reproducing the Open-IAM testing, summarizes the Open-IAM simulation results for brine and CO₂ leakage, and presents key findings to support the ongoing development of the Open-IAM. The test results showed that the current version of Open-IAM is a useful tool for the heuristic modeling of a storage project and what-if scenario modeling for brine and CO₂ leakage through wellbores. However, the current tool requires significant experience with the Open-IAM graphical user interface (GUI) and component modules and may not be easily used by nonexperts. Improvements in the ability to transfer simulations more easily from a numerical reservoir simulator to Open-IAM and the GUI input fields would likely broaden the usability of Open-IAM to a wider set of potential users, for example, regulatory stakeholders.
