The National Laboratory of the Rockies has highlighted three licensable technologies that can enable more reliable and economical deep geothermal drilling. As part of its “Fast Lane” series, the National Laboratory of the Rockies (NLR, formerly NREL) has published a summary of three licensable technologies that could help access deeper geothermal resources through reliable and cost-optimized drilling. can perform reliably at temperatures of up to 500 ºF (260 ºC), making it a viable power source for BHAs when drilling high-temperature geothermal wells. Downhole sensors and electronics suitable for harsh thermal and mechanical environments can be combined into smart systems to record and transmit drilling data during high-temperature geothermal drilling. can be combined into smart systems to record and transmit drilling data during high-temperature geothermal drilling.
