Magnitude 5.4 earthquake in South Korea

On 15 November 2017 at 05.29 UTC (14.29 local time) an earthquake with a magnitude of 5.4 occurred near Pohang in South Korea. This earthquake is the second-largest on record in Korea after the magnitude 5.8 Gyeongju event, which occurred in 2016, 40 km from Pohang. It triggered numerous aftershocks in the following months.

There may be concerns regarding a connection between the recent earthquake and the nearby Pohang geothermal project due to the close proximity and shallow depth of the earthquake. Analysis is underway regarding the injection activities in the two deep boreholes (4.3 km and 4.2 km) at Pohang. Learn more

Drilling in Westland (NL) started

Drilling in Westland (NL) started

On 6 November drilling started in Trias Westland. It will be the deepest ever performed drilling in the Netherlands. Based on a daily advance of 50 meters per day, the Buntsandstein reservoir should be reached around Christmas. Read more

Harmonic Pulse Testing as a Monitoring Tool for Enhanced Geothermal Systems

Harmonic pulse testing is a technology that has similar capabilities as regular well testing. It intends to determine hydraulic parameters such as transmissivity, wellbore storage, skin and storativity. In comparison to well testing, pulse testing has some important advantages: the deployment is simple, it can be performed during ongoing operations and it can be used as a monitoring tool. Read more on pulse testing in our best practice report.

3rd Access Programme: Joint Horizon 2020 event of DESTRESS and DEEPEGS

In the framework of the third DESTRESS access program ES-Géothermie organized two geothermal site visits on the 11 and 14 October 2017. These events, framing the European Geothermal Workshop 2016 in Karlsruhe, were a great opportunity for participants to discover two enhanced geothermal system plants in operation located in the French part of the Upper Rhine Graben.

How to Drill and Operate a Well?

Drilling a well is more than just boring into the ground. A well designer must know before drilling what is expected from the wellbore in order to determine for example its hole size diameter or possible stabilization measures. Therefore, our fourth best practice report presents a guideline to successfully drilling and operation wells. Read the full report here.

Best practices for risk assessment in geothermal projects

Best Practices for Risk Assessment in Geothermal Projects

The long timeline of a geothermal project with the drilling, construction and operation phase poses numerous risks such as legislation, accidents and public acceptance. Therefore, risks should already be assessed in the beginning of a project. Key to a reliable risk assessment are expert interviews or, wherever available, historical data. Our new best practice report deals in more detail with the topic risk assessment.

Welcome to DESTRESS

DESTRESS stands for a promising and future-oriented approach to demonstrate soft stimulation methods of EGS. We focus on solutions for the exploitation of underground heat which are economical, sustainable and environmentally responsible. Co-funded by the EU, we contribute to the European energy strategy, which targets renewable energy, greenhouse gas reduction and energy efficiency. The primarily objective of DESTRESS is to develop a comprehensive compilation of good practices for successful geothermal projects through demonstration and research.
