Geothermal drilling research overview

Sandia conducts a comprehensive geothermal drilling research program for the US Department of Energy. The program currently consists of eight program areas: lost circulation technology; advanced synthetic-diamond drill bit technology, high-temperature logging technology; acoustic technology; slimhole drilling technology; drilling systems studies; Geothermal Drilling Organization projects; and geothermal heat pump technology. This paper provides justification and describes the projects underway in each program area.
