Site Characterization Framework

Regional and project case studies, like the ARRA-funded project at the Craig site, contribute to the experience on which a carbon sequestration framework can be built. This project will contribute specifics to the carbon sequestration characterization framework guidelines for the following list of topics:


  • Buy term papers online about regional and project case studies  
  • Local and regional geologic characterization
  • Reservoir modeling and engineering
  • Providing a risk management workflow
  • Regulatory and permitting requirements
  • Community engagement to share information with and listen to the stakeholders in the local community

A framework is used to outline possible courses of action or to present a preferred approach to an idea or thought - a ‘roadmap’ that can be used as a guide during the decision making process. A characterization framework for selecting carbon sequestration sites connects all aspects of inquiry that need to be considered and evaluated to decide if a certain location, site or region shows potential for efficient and safe geological carbon storage.

The process of identifying suitable sites with adequate storage potential involves methodical analysis of the features of geologic formations at local and regional scales. While geologic formations are infinitely variable in detail, geologists and engineers generally classify them by lithology (e.g. sandstone, shale, limestone, etc), depositional environment (e.g eolian, fluvial, shallow marine, etc), mineralogy (silicates, carbonates, etc), hydraulic properties (e.g. permeability, capillary pressure, etc) and geomechanics (e.g. strength, injectivity, etc) which ultimately aid in the assessment of CO2 capacity, migration and long-term trapping mechanisms (stratigraphic, residual, solubility and mineral).
