II. IEA GEOTHERMAL R&T PROGRAMME ANNEX VII CHAPTER 5 Annex VII – Advanced Geothermal Drilling Techniques 5.1 Introduction The objective of advanced drilling technology is to promote ways and means to reduce the cost of geothermal drilling through an integrated effort which involves developing an understanding of geothermal drilling needs, elucidating best practices, and fostering an environment and mechanisms to share methods and means to advance the state of the art. Our collaborative effort has shown that drilling is expensive and can account for as much as 50% of total project cost. This observation is confounded because drilling research publications constitute less than 10% of published geothermal papers, indicating that either research and development in drilling is minimal or the time is not being taken to document status and successes. In front of the geothermal community worldwide is the need for lower drilling costs in order to make this energy source more economically accessible. Improved drilling technology will be critical for development of deeper geothermal resources and can take many forms; e.g., faster drilling rates, increased bit or tool life, less trouble (twist-offs, stuck pipe, etc.), higher per-well production through multi-laterals, and others. For example, if technological advances can be made to result in a decrease in well costs by 25%, a reduction in dry well rate by 25% and an increase in well productivity by 25% then, for a 50 MWe flash plant a cost-of-electricity reduction of 20% is achievable (Figure 5.1). Annex VII of the Geothermal Implementing Agreement has been developed to pursue advanced geothermal drilling research that will address all aspects of geothermal well construction. Participants in this Annex in 2004 were: Mexico, Iceland, the European Commission, New Zealand and the United States. Sandia National Laboratories (USA) is the Operating Agent for Annex VII. Ed Hoover was Task Leader for the first half of 2004, followed by Jack Wise, who was replaced in early 2005 by Steve Bauer (all three of Sandia Labs). 0.1 0.09 0.08 0.07 0.06 0.05 0.04 0.03 0.02 10 MW/well 3 MW/well COE ($/kWh) 0 1000 2000 3000 Depth (m) 4000 5000 Figure 5.1 Decrease in cost of electricity versus well depth for a 50 MWe plant considering technology improvements IEA Geothermal R&T Annual Report 2004.doc 35PDF Image | Geothermal Energy Annual Report 2004

Infinity Supercritical CO2 10 Liter Extractor Design and Worldwide Rights: The Infinity Supercritical 10L CO2 extractor is for botanical oil extraction, which is rich in terpenes and can produce shelf ready full spectrum oil. With over 5 years of development, this industry leader mature extractor machine has been sold since 2015 and is part of many profitable businesses. The process can also be used for electrowinning, e-waste recycling, and lithium battery recycling, gold mining electronic wastes, precious metals. CO2 can also be used in a reverse fuel cell with nafion to make a gas-to-liquids fuel, such as methanol, ethanol and butanol or ethylene. Supercritical CO2 has also been used for treating nafion to make it more effective catalyst. This NFT is for the purchase of worldwide rights which includes the design. More Info
