How water saturation affects elastic properties is particularly important for analyses of gas shales in unconventional reservoirs, but experimental data in defined partially saturated conditions are rare. We show that the elastic moduli of a gas shale vary ...
Gas shales are fine-grained, organic-rich sedimentary geomaterials with ultra-low permeability requiring hydraulic stimulation for gas extraction. Characterizing their water retention behavior is critical for predicting hydromechanical behavior and fluid f ...
Ion composition in groundwater at the spent nuclear fuel repositories is a relevant uncertainty for predicting the shear behavior of the bentonite buffer. However, only a few studies investigated the range of shear strength variation with in-situ groundwat ...
Gas shale swelling during hydraulic stimulation is one of the major challenges in unconventional gas development. It is hypothesized that the large volumetric strain upon water imbibition is a consequence of dramatic changes in capillary pressure and disjo ...
Free-standing masonry column is a recurrent typology of built cultural heritage. Usually raised without seismic design, columns are subject to intense rocking and overturning under strong ground motions. In this paper, a strategy to assess their seismic vu ...
Gas shales are usually partially saturated due to hydrocarbon generation and often have a low in-situ degree of saturation less than 40 %. During stimulation, substantial fluid imbibition into the formation occurs due to high suction. Recent research on th ...
