Carbon Sequestration Case Study: Large-Scale Exploration in a Basal Saline System in Canada and the United States
As one of the U.S. Department of Energy's regional carbon sequestration partnerships, the Plains CO2 Reduction (PCOR) Partnership is performing a case study on the feasibility of large-scale underground CO2 storage in the basal saline system of central North America. The area of investigation encompasses approximately 1,500,000 km2 of the Alberta and Williston Basins located in the provinces of Alberta, Saskatchewan, and Manitoba in Canada and the states of Montana, North Dakota, and South Dakota in the United States. The thickness of the system is up to 300 m, with a permeability range from 10 to 1250 mD and porosity ranging from 1% to 25%. The calculated static storage resource for CO2 in this saline system is 480 billion metric tons. However, the realistic injectivity is highly dependent on the reservoir pressure buildup, which must be considered during the CO2 injection and postinjection for storage resource estimation and risk assessment. In the study area, there are 16 aggregated large-scale CO2 sources. Eight scenarios were designed to address the dynamic CO2 storage capacity and pressure transient. To increase the injectivity and maximize the storage resource use, various strategies were explored, including injector optimiView/Download Document
