Computing Localized Breakthrough Curves and Velocities of Saline Tracer from Ground Penetrating Radar Monitoring Experiments in Fractured Rock
Autor: Peter-Lasse Giertzuch, Alexis Shakas, Joseph Doetsch, Bernard Brixel, Mohammadreza Jalali, Hansruedi Maurer
Publikováno v: Energies, Vol 14, Iss 10, p 2949 (2021)
Solute tracer tests are an established method for the characterization of flow and transport processes in fractured rock. Such tests are often monitored with borehole sensors which offer high temporal sampling and signal to noise ratio, but only limi

Publikováno v: Geophysical Journal International. 220:1995-2008
SUMMARY Structural joint inversion of several data sets on an irregular mesh requires appropriate coupling operators. To date, joint inversion algorithms are primarily designed for the use on regular rectilinear grids and impose structural similarity

Poroelasticity Contributes to Hydraulic‐Stimulation Induced Pressure Changes
Autor: Florian Amann, Benoît Valley, Mohammadreza Jalali, Nathan Dutler, Hannes Krietsch, Linus Villiger, Domenico Giardini, Valentin Gischig, Joseph Doetsch
Publikováno v: Geophysical research letters : GRL 48(6), e2020GL091468 (2021). doi:10.1029/2020GL091468
Geophysical Research Letters, 48 (6)
High-pressure fluid injections cause transient pore pressure changes over large distances, which may induce seismicity. The zone of influence for such an injection was studied at high spatial resolutions in six decameter-scaled fluid injection experi

Empirical investigations of the instrument response for distributed acoustic sensing (DAS) across 17 octaves
Autor: Dominik Gräff, Patrick Paitz, Joseph Doetsch, Andreas Fichtner, Athena Chalari, Cedric Schmelzbach, Pascal Edme, Fabian Walter
Publikováno v: Bulletin of the Seismological Society of America, 111 (1)
With the potential of high temporal and spatial sampling and the capability of utilizing existing fiber-optic infrastructure, distributed acoustic sensing (DAS) is in the process of revolutionizing geophysical ground-motion measurements, especially i

4D Tracer Flow Reconstruction in Fractured Rock through Borehole GPR Monitoring
Autor: Mohammadreza Jalali, Joseph Doetsch, Bernard Brixel, Peter-Lasse Giertzuch, Hansruedi Maurer, Alexis Shakas
Publikováno v: Solid Earth Discussions
Two borehole ground penetrating radar (GPR) surveys were conducted during saline tracer injection experiments in fully-saturated crystalline rock at the Grimsel Test Site in Switzerland. The saline tracer is characterized by an increased electrical c
