DESTRESS demonstrates methods of enhanced geothermal systems (EGS). The aim is to expand knowledge and to provide solutions for a more economical, sustainable and environmentally responsible exploitation of underground heat. DESTRESS will improve the understanding of technological, business and societal opportunities and risks related to geothermal energy. Existing and new project sites have been chosen to demonstrate the DESTRESS concept. The demonstration sites are using soft stimulation treatments to minimize environmental hazards.

WP5: Demonstration cyclic hydraulic and multi stage treatments in granites and tight sandstones

The demonstration of cyclic hydraulic treatments and of multi-stage stimulation in granites, granodiorites and/or in tight sandstones is a crucial part of DESTRESS. It should be shown a treatment method applied with reduced seismic and environmental risks and plannable results. Part of the work is the development of specific components for the multistage stimulation such as packer and fiber optic connection device. The experience gained through the demonstration will provide good practices or standards for future applications. These practices are expected to evolve with time as experiments from test sites and conclusions from data analysis will become available. The evaluation of the results includes the economics.
