Sim-SEQ

The Sim-SEQ project was created to objectively evaluate the modeling efforts of different research groups as they model the Phase III geologic carbon storage field tests undertaken by the U.S. Department of Energy’s Regional Carbon Sequestration Partnerships (RCSP) over the next several years. Fifteen research teams from eight countries will attempt to correctly predict the behavior of an injected carbon dioxide plume at a RCSP site in Cranfield, Mississippi. One of the main goals of the Sim-SEQ project is to conduct comparisons of multiple subsurface models and demonstrate that the system behavior observed at a geologic carbon storage site can be accurately predicted even with variations in approaches to model development for the same injection data. For this project to be successful, modeling teams must be able to easily share, query, and update a wide variety of information, including site characterization data and simulation results. Each team will develop models independently so the Sim-SEQ coordinators must be able to evaluate these models collectively. PNNL’s Geologic Sequestration Software Suite (GS3) provides the Sim-SEQ project with a collaborative framework as well as tools to assist the project coordinators and team members with model comparisons. GS3 is a computational platform that enables users to compare model performance and identify choices made during the model development process that may affect a model’s performance.
