Short Course 2

1. Basics of geothermal energy production (1 hour)
2. Basics of reservoir simulation (1 hour)

Next, we will proceed with practical exercises in Jupyter Notebooks using open-DARTS.

1. In this exercise (2 hours) we will learn about the main steps in creating a basic static and dynamic geothermal model in 1D by:
   • Set the main simulation parameters
   • Define the simulation grid
   • initialize reservoir parameters
   • Define boundary and initial conditions
   • Run and process the simulation results.
   • Look into the effect of model resolution, timestep, and sensitivity on two major thermal properties – rock heat capacity and conduction.
2. In this exercise (1.5 hours), we will start with a perfect homogeneous 3D reservoir and learn the effect of overburden and what is the best strategy to model it in geothermal models.
   • We will also load heterogeneous permeability representing fluvial sediments to understand how the direction of channels will affect the lifetime of the geothermal system and final energy production. 
3. The last exercise (2 hours) is dedicated to geothermal energy production from fractured systems. We will evaluate the sensitivity of energy production to well position, initial fracture aperture, and stress orientation.
4. The course will be concluded by a short discussion (0.5 hours) on lessons learned and practical recommendations for real-world geothermal applications.
