CX-001190: Categorical Exclusion Determination

An Integrated Experimental and Numerical Study: Developing a Reaction Transport Model that Couples Chemical Reactions of Mineral Dissolution/Precipitation with Spatial and Temporal Flow Variations in Carbon Dioxide/Brine/Rock Systems
CX(s) Applied: A9, B3.6
Date: 03/21/2010
Location(s): Minneapolis, Minnesota

The University of Minnesota would develop a model for chemical interactions between super-critical carbon dioxide and enhanced geothermal system (EGS) reservoir rocks and their effects on modifications of pore space geometries and related reservoir rock porosity and permeability owing to mineral dissolution/precipitation processes. All project work would occur on the campus of the University of Minnesota in Minneapolis, Minnesota.
