| Abstract | A world-wide review of geothermal drilling operations and technology developments indicates that geothermal drilling practices and equipment are derived largely from existing water- well, mining, and oil and gas developments. Technology improvements to enhance drilling performance in hightemperature and harsh geothermal conditions have been mostly limited to incremental adaptations. A design concept for an advanced geothermal system is presented. |
