National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Evaluation of the Impact of CO2, Aqueous Fluid, and Reservoir Rock Interactions on the Geologic Sequestration of CO2, with Special Emphasis on Economic Implications.

DE200515013304

Publication Date	2004
Personal Author	Knauss, K. G.; Johnson, J. W.; Steefel, C. I.; Nitao, J. J.
Page Count	18
Abstract	Lowering the costs of front-end processes in the geologic sequestration of CO2 can dramatically lower the overall costs. One approach is to sequester less-pure CO2 waste streams that are less expensive or require less energy to separate from flue gas, a coal gasification process, etc. The objective of this research is to evaluate the impacts of an impure CO2 waste stream on geologic sequestration using both reaction progress and reactive transport simulators. The simulators serve as numerical laboratories within which a series of computational experiments can be designed, carried out, and analyzed to quantify sensitivity of the overall injection/sequestration process to specific compositional, hydrologic, structural, thermodynamic, and kinetic parameters associated with the injection fluid and subsurface environment.
