PESA SA/NT June Luncheon
Guest Speaker(s): Markus Häring
Markus Häring holds an MSc and a PhD in Earth Sciences of the University of Basel. His first ten years he worked for Shell as exploration geologist on four continents. With his own company Geothermal Explorers, he initiated and operated the Deep Heat Mining project in Basel. From 2007 till 2019 Markus was a member of the Swiss Federal Geological Commission. He is an expert in advanced drilling systems for geothermal energy, the disposal of nuclear waste and CO2-sequestration. From 2017 – 2023 he advised the Swiss Nuclear Safety Inspectorate ENSI on advanced drilling technologies in designated repository formations of nuclear waste. Markus is co-founder of the Carnot-Cournot-Network, a think tank for policy advice in technology and economics. He is the author of the books “The 2000 Watt Fallacy” and “Scapegoat CO2”.
PESA SA/NT June Luncheon
The impact of triggered earthquakes of the Basel geothermal project 2006 on Engineered Geothermal Systems
Markus Häring (Consultant)
The triggered earthquake of M 3.4 with subsequent events of M >2 was a turning point in the perception of induced seismicity caused by intentional pressure changes in the subsurface. The events followed a massive hydraulic stimulation into granitic basement at 5 km depth below the city of Basel.
The geothermal project attracted worldwide attention, not only because the seismicity was felt throughout the city, but also because, for the first time, induced seismicity was recorded in detail by a scientifically supported monitoring system.
Since then, microseismic monitoring systems have been greatly improved and can now be used in all underground operations where pressure changes occur, such as oil and gas production, fraccing, CCS and EGS.
