In SECURE, mainly cracking, crack growth and microseismicity in reservoir rocks before, during and after use were investigated. An important goal was the development of cross-scale physical models to explain stress and pore pressure changes and the resulting induced seismicity for different reservoir types and uses. The results can be found in the research report on DGMK project 803 SECURE - Sustainable and environmentally friendly use and conservation of underground reservoirs view. The report has been published and is available to order free of charge.
