| Abstract | The geothermal well cost model developed by Sandia National Laboratories is being used to analyze the sensitivity of well costs to improvements in geothermal drilling technology. This paper discusses three interim results from this modeling effort: the sensitivity of well cost to bit parameters, rig parameters, and material cost; an analysis of the cost reduction potential of an advanced bit; and a consideration of breakeven costs for new cementing technology. All three results illustrate that the well cost savings arising from any new technology will be highly site dependant but that in specific wells the advances considered can result in significant cost reductions. |
