Rocky Mountain Regional CO 2 Storage Capacity and Significance

The purpose of this study includes extensive characterization of the most promising geologic CO 2 storage formations on the Colorado Plateau, including estimates of maximum possible storage capacity. The primary target of characterization and capacity analysis include the Cretaceous Dakota Formation, the Jurassic Entrada Formation and the Permian Weber Formation and their equivalents in the Colorado Plateau region. The total CO 2 capacity estimates for the deep saline formations of the Colorado Plateau region range between 9.8 metric GT and 143 metric GT, depending on assumed storage efficiency, formations included, and other factors.

CO 2 Sequestration Capacity and Associated Aspects of the Most Promising Geologic Formations in the Rocky Mountain Region: Local-Scale Analyses

The purpose of this report is to provide a summary of individual local-scale CCS site characterization studies conducted in Colorado, New Mexico and Utah. These site- specific characterization analyses were performed as part of the “Characterization of Most Promising Sequestration Formations in the Rocky Mountain Region” (RMCCS) project. The primary objective of these local-scale analyses is to provide a basis for regional-scale characterization efforts within each state. Specifically, limits on time and funding will typically inhibit CCS projects from conducting high- resolution characterization of a state-sized region, but smaller (< 10,000 km 2 ) site analyses are usually possible, and such can provide insight regarding limiting factors for the regional-scale geology. For the RMCCS project, the outcomes of these local-scale studies provide a starting point for future local-scale site characterization efforts in the Rocky Mountain region.

CCS Project Permit Acquisition Protocols

Geologic carbon storage projects require a vast range of permits prior to deployment. These include land-access permits, drilling permits, seismic survey permits, underground injection control permits, and any number of local and state permits, depending on the location of the project. For the “Characterization of Most Promising Sequestration Formations in the Rocky Mountain Region” (RMCCS) project in particular, critical permits included site access permits, seismic survey permits, and drilling permits for the characterization well. Permits for these and other activities were acquired either prior to or during the project.

Simulation model analysis of the most promising geological sequestration formation candidates in the Rocky Mountain region, USA, with focus on uncertainty assessment

The purpose of this report is to report results of reservoir model simulation analyses for forecasting subsurface CO 2 storage capacity estimation for the most promising formations in the Rocky Mountain region of the USA. A particular emphasis of this project was to assess uncertainty of the simulation-based forecasts. Results illustrate how local-scale data, including well information, number of wells, and location of wells, affect storage capacity estimates and what degree of well density (number of wells over a fixed area) may be required to estimate capacity within a specified degree of confidence. A major outcome of this work was development of a new workflow of simulation analysis, accommodating the addition of “random pseudo wells” to represent virtual characterization wells.
