| Abstract | Geothermal energy is the cleanest form of alternative energy, because it has the least environmental impact. The United States has vast untapped geothermal energy potential; using enhanced geothermal systems (EGS) technology, geothermal wells can supply the energy consumption for the USA for 2,000 years [1]. The Department of Energy (DOE) spearheads research and innovation in tools and technologies required for successful and economical use of EGS reservoirs. Temperatures in some EGS reservoirs can exceed 300°C. This paper provides a status update and technology review for ?high temperature 300°C directional drilling system, including drill bit, steerable motor, and drilling fluid, for enhanced geothermal systems,? being developed with funding assistance from DOE (DE-EE0002782). We are close to delivery on the directional drilling systems tools. The drill bit, motor and fluid were all been developed for operation at 300°C; a complete drilling system was assembled and tested at the Baker Hughes Experimental Test Area (BETA), Oklahoma, and the drilling parameters and test results are provided. |
