- This document presents the material used in an oral presentation to the DOE/Division of Geothermal Energy, which was designed to illustrate the importance of well technology development in reducing geothermal well costs, and to achieve geothermal power-on-line goals. Examination of recent studies of the economics of geothermal energy leads to the conclusion that the overall sensitivity of geothermal power-on-line to well cost is in the range of one to two. Current data suggest that a vigorous R and D program in rotary drilling technology can reduce geothermal drilling costs by about 20%, but a reduction of 40 to 50% is needed to achieve DOE/DGE goals. Research in advanced drilling systems is needed to satisfy this more stringent requirement. Some critical technological deficiencies that occur when current rotary drilling techniques are used for geothermal drilling are discussed. A broadly based development program directed at correcting these deficiencies is defined.
