Carbon neutral, scalable, time-responsive, geographically distributed and economically appealing solutions to sustainable electric power generation, achievable through drilling & completions tech in horizontal wells up to 400°C

Enabling the Transition to a Carbonless Future

Arrow Geothermal is an established geothermal energy company located in Calgary, Alberta, that has developed novel drilling and completion technologies to exploit the potential of Hot Dry Rock (HDR) up to 400°C globally.

We have developed HDR technology to drill and produce the hottest horizontal geothermal wells in the world. Our techniques have created billions of dollars in value in the hydrocarbon industry. Arrow Geothermal will provide baseload electricity to economically enable the transition to a carbonless future.

Our approach provides a dramatically more efficient energy transfer with higher formation contact and flow rates.
