Petrophysical joint inversion applied to alpine permafrost field sites to image subsurface ice, water, air, and rock contents

Mollaret, Coline ; Wagner, Florian M. ; Hilbich, Christin ; Scapozza, Cristian ; Hauck, Christian

In: Frontiers in Earth Sc-ience, 2020, vol. 8, p. -

Quantification of ground ice is crucial for understanding permafrost systems and modeling their ongoing degradation. The volumetric ice content is however rarely estimated in permafrost studies, as it is particularly difficult to retrieve. Standard borehole temperature monitoring is unable to provide any ice content estimation, whereas non-invasive geophysical techniques, such as refraction ...

An analytical algorithm of porosity–permeability for porous and fractured media: extension to reactive transport conditions and fitting via flow-through experiments within limestone and dolomite

Erol, Selçuk ; Fowler, Sarah Jane ; Nehler, Mathias ; De Boever, Eva ; Harcouët-Menou, Virginie ; Laenen, Ben

In: Transport in Porous Media, 2019, vol. 129, no. 1, p. 343–383

Accurate prediction of permeability evolution is essential for forecasting the long-term performance and lifetime of hydrothermal reservoirs, an important goal in the geothermal, ore, and petroleum industries. Erol et al. (Transp Porous Media 120(2):327–358, 2017. https://doi.org/10.1007/s11242-017-0923-z) introduced a general (non-empirical) analytical Kozeny–Carman type equation for...
