In the last blog we mentioned that many operators we have spoken to are interested in the transfer of horizontal well technology from the oil
A recent article in Journal of Petroleum Technology (JPT) magazine https://jpt.spe.org/microwave-drilling-sounds-like-science-fiction-but-so-does-drilling-down-to-the-hottest-rock describes the plans of a new drilling technology company, Quaise Energy, to utilise microwave

Hello Hephae team,
Great talk, congrats.
My background is directional drilling and well engineering and contruction (40 years – 10 with SLB D&M, 20 with TOTAL, 10 with DrillScan as associate and CTO/CEO, DrilScan is now 100% H&P Inc since 2019)
I’m consulting with my new company RG2S – Consulting for Geothermal promotion.
I’m currently projecting how to replace russian gas imports in France and how geothermal AGS wells could help.
Very preliminary finding at France scale are:
– 350 geothermal plants fed by 12 U shape wells (sedimentary rock – 150°C – 3500-4000m TVD – 14km total drilled per loop) for cities ranging 25000 – 100000+ people (more than 350 French cities in that range)
– 20 rigs (45-60 days AFE per loop)
– Cost per drilled cluster 165M€ (estimated after 2 years learning curve benefits – cost per drilled meter in Europe is much higher than in USA, but will improve considerably)
– 15 plants delivered per year from 2025 to 2050 (very likely faster, thanks to factory drilling approach)
– Each plant producing 240MWh/year
– Geothermal production capability (thermal / electricity) in 2050 : 84 TWh/year (that is France gaz imports from Russia per year and it cost anything between 2 and 8 G€/year, averaging 130G€ over 25 years)
– Overall CAPEX by 2050 of 58G€ and very low OPEX
– AGS well life cycle of 50 years
– Cost per kWh over 30 years depreciation is 0.03€ / 50 years 0.01€)
