    The objective of this course is to provide a holistic coverage of advanced topics in geothermal heat production from various types of geothermal sources including hydrothermal, fractured EGS (high enthalpy), and hot saline aquifers (low enthalpy) resources. The emphasis is the use of predictive theoretical and computational models, alongside practical and real-world based test cases and exercises. We introduce the governing equations for Cartesian and radial coordinates, single and multiphase geothermal flow, and integrated thermodynamics with fluid flow. We cover the advanced topics related to techno-economics of calculating levelized cost of energy from geothermal sources. The cost analysis is conducted similarly for various types of geothermal reservoirs. Additionally, the advances in utilizing CO2 as the working fluid (a CCUS technology) to extract heat from geothermal reservoirs is covered in the course. Finally, operational aspects of maintaining geothermal wells such as acidizing process, geochemistry of scaling/remediation and closed-system geothermal well design are presented along practical case studies.
