Abstract Knowledge of the present-day crustal in-situ stress field is a key for the
understanding of geodynamic processes such as global plate tectonics and earthquakes. It …

Hydraulic fracturing (HF) is a technique that is used for extracting petroleum resources from
impermeable host rocks. In this process, fluid injected under high pressure causes fractures …

Geothermal energy is a renewable energy source that can be found in abundance on our
planet. Only a small fraction of it is currently converted to electrical power, though in recent …

Effective methane extraction in underground coal seams can improve the efficient utilization
of fossil energy and reduce the risk of safety accidents in coal mines. Pulsating nitrogen …

The purpose of this paper is to provide a comprehensive state of the art of fatigue and cyclic
loading of natural rock materials. Papers published in the literature are classified and listed …

The world's primary energy requirements are supplied to a large extent by non-renewable
energy resources, which has resulted in significant anthropogenic greenhouse gas …

In this overview we report results of analysing induced seismicity in geothermal reservoirs in
various tectonic settings within the framework of the European Geothermal Engineering …

In this contribution, we present a review of scientific research results that address seismo-
hydromechanically coupled processes relevant for the development of a sustainable heat …

Injection-induced seismicity has become a major barrier to the development of geothermal
energy, because the complexity of fault behaviors and the lack of physical fundamentals …

A modified distinct element Voronoi method, which we refer to as “Trigon” logic, is proposed
for use in both two and three-dimensional modelling. A rock material is represented by an …
