Sim-SEQ
A Collaborative Initiative on Evaluation of Modeling Approaches Using Results from Large-Scale CO2 Field Tests in the USA
Sim-SEQ is a multi-year collaborative initiative aiming to objectively evaluate the modeling efforts of different research groups as they are applied to geologic carbon sequestration (GCS) field tests in the United States. The Regional Carbon Sequestration Partnerships (RCSP) in the United States are currently in the planning stages for deployment-phase (Phase III) field tests involving geologic storage of more than one million tons of CO2, at rates on the order of several hundred-thousand tons of CO2 per year. The overall goals of Sim-SEQ are to (1) enhance confidence in model predictions of these GCS sites, (2) evaluate model uncertainty stemming from different model approaches, (3) provide a forum for multidisciplinary interactive and cooperative research, and (4) encourage development of new approaches and improvements in modeling and simulation, if necessary. Sim-SEQ activities are centered around a Sim-SEQ technical team comprised of the RCSP modeling groups involved in conducting and modeling the field tests. Experts at the Lawrence Berkeley National Laboratory (LBNL) manage and coordinate the model comparison effort, supported by an external scientific advisor. The initiative was started in a kick-off meeting held on October 8, 2008.
Over the next several years, Sim-SEQ will allow, in a collaborative setting, review and discussion of the modeling activities related to ALL ongoing RCSP large-scale field experiments (see MSA Approach). In addition, one of these large-scale field experiments, preferably one that provides early data and that is reasonably representative in terms of modeling challenges, will be selected as a designated test case for all Sim-SEQ members (see MMA Approach). The different modeling groups established by the partnerships will each develop individual models for this one selected site, based on a single set of site characterization data, but using their respective model approaches and simulators. This will allow for a direct comparison and interaction between multiple RCSP modeling groups. Selection of the designated site is underway. International modeling teams are welcome to join in this collaborative effort.
The Sim-SEQ initiative is supported by the U.S. Department of Energy, Office of Fossil Energy, National Energy Technology Laboratory (NETL).
