Introduction

Analytical models are mathematical models that have a closed form solution. Or in other words the solution to the equations used to describe changes in a system can be expressed as a mathematical analytic function.

Modeling Techniques

Data Access and Acquisition

Matching the analytical model solutions with measured data can provide verification of assumptions on the geothermal reservoir.

Best Practices

In analytical modeling it is very important to identify the main factors defining the complex system. Doing this can help provide guidance and what needs to be measured to understand the subsurface processes.

Potential Pitfalls

Analytical modeling can become more complicated if the number of variables solved for increases.
