Project workshop of geo2spain, GSS-VET, Geozert and GeoTrainet at German Geothermal Congress

The availability of qualified personal is a bottleneck for the expansion of shallow geothermal energy in many countries. Specific knowledge for heting installers as well as for drilling staff or planners and designers. The workshop presents the training course approaches of the projects geo2spain, GSS-VET, Geozert and GeoTrainet. In a second part the participants are invited to an open discussion.

In “Vocational Education and Training in Europe: The GSS-VET Project” our Technical Director Gregor Rumberg will report about the latest project results, the implementation of innovative teaching methods, experiences from the international collaboration and a possible utilization on the German market.

Date: 19. November 2019, 14:00 – 17:40

Radial Water Jet Drilling (RJD) is a common technology to stimulate oil and gas wells in sedimentary formations. Within the EC funded Horizon 2020 project SURE (Novel Productivity Enhancement Concept for a Sustainable Utilization of a Geothermal Resource) the radial jet drilling technology was investigated and tested as a method to increase performance of insufficiently performing geothermal wells.

The technology: Radial jet drilling uses the power of a focused jet of fluids, applied to a rock through a coil inserted in an existing well. This technology is likely to provide much better control of the enhanced flow paths around a geothermal well and does not involve the amount of fluid as conventional hydraulic fracturing, thereby reducing the risk of induced seismicity considerably. RJD shall be applied to access and connect high permeable zones within geothermal reservoirs to the main well with a higher degree of control compared to conventional stimulation technologies.

A European consortium of geoscientific and applied technical research institutions, specialized universities, a dedicated technology provider and a geothermal company investigated the technology over various spatial and temporal scales ranging from short term laboratory experiments to field scale applications.

The results show that RJD is an innovative stimulation technology with a high potential for geothermal applications, but there are some technical challenges that need to be addressed in future work.

Related publications and more information about the SURE project are available on the project website
Detailed scientific results will be presented at the World Geothermal Congress 2020 in Reykjavik.

Call for papers: Tracers in Deep Geothermal Systems

Contributions are now being accepted. This special issue addresses tracer investigations in geothermal systems to characterize the critical properties of geothermal reservoirs. Contributions may address new tracers or tracer test methods, and may involve single-well to multi-well tests with conservative and reactive tracers, novel tracer substances – like temperature tracing compounds and particle tracers – and environmental tracers. As tracer tests in such settings sometimes produce “strange” results and may even fail because the hydrogeological setting differs from expectations, papers addressing the reasons for anomalous results are equally welcome. Contributions utilizing chemical composition and isotope signatures to describe regional flow paths and influx from overlying and underlying strata are also sought to complement the inter-well tracer tests.

Submissions may include but are not restricted to the following topics: single-well tracer tests, multi-well tracer tests, thermal tracers, isotope tracers, thermal breakthrough, and heat exchange in reservoirs.

The book was few years in the making and I am sure it will be a new significant contribution to the industry. It is very applied and covers all technical aspects of the geothermal well.

25 – 27 Nov – 41st Geothermal Workshop!

This meeting is the first of its kind to be held in Canada. Organized by students and for students the event aims to bring together graduate students to post-doc fellows from Canada’s East to West coasts to discuss and share their research projects related with the field of geothermal energy.

Beyond inspirational speakers and students’ presentations, more activities are scheduled, such as a visit to the INRS Open Geothermal Lab.

There are no inscription fees for students willing to present their work. Depending on the number of attendees, travel grants might be possible to arrange. Find more information here.

Dr. Andrew Sabin is the new President of the GRC

Davis, California, USA. The Geothermal Resources Council (GRC) has welcomed Dr. Andrew Sabin as the 27th President of the global geothermal energy organization, succeeding Maria Richards. Dr. Andrew Sabin works with the Navy Geothermal Program Office in Ridgecrest, California. Andy’s career has spanned more than 30 years and has included ore deposits, geotechnical, environmental and geothermal work. He earned degrees in geology from the University of Maryland, the University of Pittsburgh and the Colorado School of Mines. Like many of his colleagues in the geothermal energy community, Andy has been a long-time member and supporter of the GRC. He also currently serves on the Board of Directors for the International Geothermal Association (IGA). According to Dr. Sabin, “If someone is fortunate enough to be employed in this industry for any amount of time, participating in and then giving back to the GRC should be an expectation. I’d encourage all leaders in this industry to motivate their peers and their employees to join and then actively participate in the GRC. The costs and the time spent each year are nominal. The potential benefits to their careers and to our industry are immeasurable.”

About the Geothermal Resources Council: The Geothermal Resources Council (GRC) will be celebrating 50 years of service to the global geothermal energy community in 2022. The GRC is dedicated to advancing geothermal development around the world through education, research, and outreach. For more information, please visit
