In the last three days leading up the World Geothermal Congress in Melbourne, David attended an invigorating course in techniques for de-risking geothermal drilling.

The main lecturer was the guy pictured with David: Hagen Hole. Hagen is one of the most experienced geothermal drilling engineers, having over 40 years experience drilling in over 25 countries. He has helped pioneer geothermal energy in many of the most volcanically active regions in the world.

Thank you Hagen for answering the numerous questions David had and providing a wealth of valuable insights. We really hope to have the opportunity to work with you before you take a much deserved retirement.
