Geothermal Energy Engineering: Technology Transfer from the Oil and Gas Industry focuses on geothermal energy technology, engineering, field, and operational topics as seen from an oil and gas industry perspective. To accelerate development of an important source of clean energy during the energy transition, proven oil and gas technologies can pivot towards geothermal energy production, for both power generation and direct heat applications. The book's chapters are written by world-renewed subject matter experts who address practical applications optimized in the oil and gas industry that can be adapted to accelerate geothermal energy production. The book progresses from an introduction to geothermal energy, cover types of geothermal and hybrid systems, address geothermal subsurface characterization, exploration, drilling, completion and production, facilities and project management, and includes analysis of technical and economic aspects of geothermal systems, gaps and future opportunities.
