Enhanced Geothermal System
Enhanced Geothermal Systems (EGS) are modern ways of getting energy from the Earth's heat, even in places where traditional geothermal energy wouldn't work. Think of it like creating an underground radiator - engineers inject water into hot rocks deep underground, heat it up, and bring it back to the surface to make electricity. It's different from regular geothermal because it can work almost anywhere, not just in naturally hot spots like Iceland or New Zealand. This technology helps expand where we can produce clean, renewable energy.

Example Interview Questions
Senior Level Questions
Q: How would you manage risks in an Enhanced Geothermal System project?
Expected Answer: A senior candidate should discuss managing drilling risks, reservoir development challenges, community engagement, environmental impact assessment, and having backup plans for technical issues. They should emphasize safety protocols and monitoring systems.
Q: What strategies would you use to optimize an EGS plant's performance?
Expected Answer: Look for answers about monitoring well pressure, maintaining optimal flow rates, preventing mineral buildup, managing pump systems, and using data to make operational decisions. They should mention experience with similar projects.
Mid Level Questions
Q: Explain the main differences between traditional geothermal and Enhanced Geothermal Systems.
Expected Answer: Should explain how EGS creates artificial reservoirs in hot rock versus using natural hot springs, and discuss basic drilling and stimulation processes in simple terms.
Q: What are the key factors in selecting an EGS site?
Expected Answer: Should mention rock temperature, depth considerations, water availability, proximity to power grid, and environmental factors. Understanding of basic geology and local regulations is important.
Junior Level Questions
Q: What safety considerations are important in geothermal operations?
Expected Answer: Should demonstrate awareness of basic safety protocols, handling hot fluids, pressure management, and importance of protective equipment and following safety guidelines.
Q: How does an Enhanced Geothermal System produce electricity?
Expected Answer: Should be able to explain the basic process: injecting water, heating it underground, pumping it up, and using the steam to generate power, even if they don't know all technical details.
