1. Overview of Modeling J.S. Gierke 28 September 2000

2. Types of Models (Terminology) Conceptual: Drawing, Interpreted, Facies Physical: Hands-on Mathematical: Governing Equations –Theoretical: Differentiated by Solution Approach Analytical: Ideal Geometry, Constant Conditions Numerical: Real Conditions, Nonlinear effects –Empirical: Observation Based

3. Purposes of Modeling Test Hypotheses “Back-Calculate” Parameters/Conditions Predictive Tool for Forecasting Conditions –“What if?” –Optimization: Minimize Cost/Maximize Benefit –Estimate Costs and Performance

4. Modeling Process
