| Abstract | The impacts of technological improvements in drill bits on geothermal well costs are evaluated using a compilation of well costs associated with conventional drilling technology. The compilation centers around well models that have been constructed for the major U.S. geothermal areas, Parametric analyses showing the relative importance of the bit performance parameters in well cost reduction and the results of analyses of specific new bit technologies are presented. These results have been used to evaluate the benefits of new technologies and to direct their development. |
