Course Content

Carbon dioxide capture and storage (CCS) is one of the key approaches to reducing CO2 emissions from the energy and industrial sectors. Having a clear understanding of geologic CO2 storage resources across multiple basins is important for national and regional planning purposes. Using a method that honors geologic heterogeneity and has been tested in a wide variety of sedimentary basins and geologic settings is important for estimating those storage resources.

The U.S. Geological Survey’s CO2 storage resource assessment methodology was used to estimate the storage resources of the entire United States and can be used in any setting anywhere in the world. The results can be directly compared to the U.S. storage resources and to understand similar resources in international settings.

The objective of the short course  is to provide in-depth training on the USGS CO2 storage assessment methodology and how to proceed with an assessment. The course is designed for geoscientists responsible for estimating geologic CO2 storage resources.

Topics to be covered during the course include:

  • Introduction to Geologic CO2 Storage
  • CO2 Storage Options and Trapping Mechanisms
  • Overview of Existing CO2 Storage Assessment Methodologies
  • CO2 Storage Assessment Process
  • Identification and Selection of Suitable CO2 Storage Sites
