Abstract
Rock properties such as density, porosity, and permeability govern the mechanical behavior of rocks and productivity of aquifers. However, heterogeneity in rock properties contributes to uncertainty in reservoir modeling; and it may be best to provide ways to make data easier to work with. This study examines variability in rock properties by classification of lithology and minerology in Icelandic geothermal systems. Databases used include the IMAGE database, Valgardur database, and data collected by Levy and Covell for the Krafla area. The aim is to find the best way to represent data through proper cohesion of grain density, total porosity, and Klinkenberg permeability measurements based on lithology and minerology.
