Three-dimensional hydraulic fracture propagation in homogeneous and heterogeneous media
Hydraulic fractures are tensile fractures that occur in solid materials due to the natural intrusion or anthropogenic injection of a viscous fluid into a fracture channel. The deliberate creation of hydraulic fractures is part of an industrial technology h ...
EPFL2023Reactivation of variably sealed joints and permeability enhancement in geothermal reservoir rocks
Alexandra Roma Larisa Kushnir, Michael Heap
Hydraulic stimulation of enhanced deep geothermal reservoirs commonly targets pre-existing joint networks with the goal of increasing reservoir permeability. Here, we study the permeability and strength of joint-free and jointed Buntsandstein sandstones fr ...
2023Physical characterization of fault rocks within the Opalinus Clay formation
Marie Estelle Solange Violay, Christophe Nussbaum, Luis Felipe Orellana Espinoza
Near-surface disposal of radioactive waste in shales is a promising option to safeguard the population and environment. However, natural faults intersecting these geological formations can potentially affect the long-term isolation of the repositories. Thi ...
