Demonstration of soft stimulation treatments of geothermal reservoirs

Descripción del proyecto

Romper suavemente rocas calientes para aprovechar el calor de los yacimientos geotérmicos

El núcleo de la Tierra es un horno increíblemente caliente. Parte de su calor llega a la corteza y es accesible a los humanos. Los sistemas geotérmicos mejorados están diseñados para aprovechar este calor como forma sostenible de energía para diversos fines, incluida la generación de electricidad. Estos sistemas inyectan fluido en el suelo, provocando la reapertura de las fracturas preexistentes y permitiendo que el fluido circule y absorba el calor. A partir de proyectos anteriores y de los avances científicos en otros ámbitos (principalmente el sector del petróleo y el gas), el equipo del proyecto DESTRESS, financiado con fondos europeos, adaptará a las aplicaciones geotérmicas métodos de «estimulación» desarrollados recientemente. El equipo se centrará en la «estimulación suave», abordando así la preocupación pública relacionada con la fracturación hidráulica.

Objetivo

DESTRESS is aimed at creating EGS (Enhanced geothermal systems) reservoirs with sufficient permeability, fracture orientation and spacing for economic use of underground heat. The concepts are based on experience in previous projects, on scientific progress and developments in other fields, mainly the oil & gas sector. Recently developed stimulation methods will be adapted to geothermal needs, applied to new geothermal sites and prepared for the market uptake. Understanding of risks in each area (whether technological, in business processes, for particular business cases, or otherwise), risk ownership, and possible risk mitigation will be the scope of specific work packages.
The DESTRESS concept takes into account the common and specific issues of different sites, representative for large parts of Europe, and will provide a generally applicable workflow for productivity enhancement measures. The main focus will be on stimulation treatments with minimized environmental hazard (“soft stimulation”), to enhance the reservoir in several geological settings covering granites, sandstones, and other rock types. The business cases will be shown with cost and benefit estimations based on the proven changes of the system performance, and the environmental footprint of treatments and operation of the site will be controlled. In particular, the public debate related to “fracking” will be addressed by applying specific concepts for the mitigation of damaging seismic effects while constructing a productive reservoir and operating a long-term sustainable system.
Industrial participation is particularly pronounced in DESTRESS, including large energy suppliers as well as SMEs in the process of developing their sites. The composition of the consortium involving major knowledge institutes as well as key industry will guarantee the increase in technology performance of EGS as well as an accelerated time to market.
