Large-Scale CO2 Storage Exploration in a Basal Saline System in Canada and the United States
As one of the U.S. Department of Energys Regional CarbonSequestration Partnerships, the Plains CO2 Reduction (PCOR)Partnership is studying the feasibility of large-scale underground CO2 storage in the basal saline system of central North America. Thearea of investigation encompasses approximately 1,500,000 km2 ofthe 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 calculatedstatic storage resource for CO2 in this saline system is 480 billion metrictons. However, realistic injectivity is highly dependent on the reservoirpressure buildup, which must be considered during CO2 injection andpostinjection for storage resource estimation and risk assessment.In the simulation area, the large-scale CO2 sources emit 104 Mt CO2/yr.Sixteen cases were designed to address the dynamic CO2 storagecapacity and pressure transient. To increase the injectivity and maximizethe storage resource use, various strategies were explored, includinginjection optimization, multiple well patterns, water extracView/Download Document
