This 37 page course discusses design aspects of enhanced geothermal systems (EGS), as opposed to conventional, naturally-occurring convective geothermal systems. The vast majority of geothermal energy within drilling reach is in dry non-porous rock. To convert this geologic medium into a viable geothermal resource requires fracturing the rock through a process called hydraulic stimulation, in order to improve fluid flow through the hot rock.

Topics: Introduction to Geothermal Energy Introduction to the Enhanced Geothermal Concept Assessment of the Assumptions in the MIT Study Geothermal and Recoverable Resources EGS Well Drilling Reservoir Creation, Operation, and Maintenance EGS Costs Evaluation Technology for EGS Reservoir Development Finding the Site – Site Characterization Finding the Site – Exploratory Well and Reservoir Characterization of the Well Creating the Reservoir – Injection Well Creating the Reservoir – Stimulation Completing the Well Field Operating and Maintaining the Reservoir.

Intended Audience: electrical, mechanical, civil, energy, chemical, environmental, construction,and industrial engineers. However, this course could appeal to engineers of other disciplines as well.
