Project Description

This project is focused on studying performance of CO₂ storage at a Rock Springs Uplift (RSU) potential storage site in southwestern Wyoming using a multidisciplinary approach that integrates observational, experimental, and theoretical data with numerical simulations and determinations of seismic attributes. The objectives include: (1) Reduce uncertainty in estimates of CO₂ storage capacity at the RSU; (2) Evaluate and ensure CO₂ storage permanence at the RSU site by focusing on the sealing characteristics and 3-D interval heterogeneity of the confining layers; (3) Improve the efficiency of potential storage operations by designing an optimal coupled CO₂ injection/brine production strategy that ensures effective pressure management; and (4) Improve the efficiency of brine production in the RSU relative to mineral scaling.

Project Benefits

This project focuses on advancing the characterization and assessment of the RSU in Wyoming as a carbon storage resource. This project is improving estimates of CO₂ storage reservoir capacity, evaluating the long-term integrity and performance of confining layers, and managing injection to optimize CO₂ storage efficiency, thereby contributing to better storage technology thus reducing CO₂ emissions to the atmosphere. The effort focuses on the sealing characteristics and 3-D interval heterogeneity of the confining layers and improving the efficiency of potential storage operations.
