Monitoring Fracture Hydromechanical Evolution in the Lab and Field Using Unsupervised Metric Learning

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 3, September 2025.
Abstract Fractures evolve in time through thermal‐hydraulic‐mechanical‐chemical (THMC) processes that alter their long‐range hydraulic transport properties and modify subsurface behavior and activities. The location of subsurface fractures makes it necessary to use remote sensing techniques such as passive or active seismic monitoring for fracture ...

Anderson's considerations on the flow of superfluid helium: some offshoots [PDF]

, 2015
Nearly five decades have elapsed since the seminal 1966 paper of P.W. Anderson on the flow of superfluid helium, $^4$He at that time. Some of his "Considerations" -- the role of the quantum phase as a dynamical variable, the interplay between the motion ...

Development of 1D Hybrid Hydromechanical Models for Real‐Time Forecasting of Induced Seismicity Rate

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 8, August 2025.
Abstract Hydraulic stimulations play an important role in Enhanced Geothermal Systems (EGS) by increasing the permeability of the host rock and facilitating more efficient fluid circulation and heat extraction. However, fluid injection operations are unavoidably accompanied by induced earthquakes.

Co‐Evolution of Specific Stiffness and Permeability of Rock Fractures Offset in Shear

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 5, May 2025.
Abstract Fractures and faults represent planes of weakness and compliance in rock masses that serve as focal points for both microearthquakes and fluid transport, with seismicity and permeability evolution closely linked. Contact stiffness is highly stress‐sensitive and directly influences permeability. We explore the co‐evolution of specific stiffness

Multi‐Frequency Oscillatory Hydraulic Tomography Improves Heterogeneity Imaging and Resolution and Reduces Uncertainty

Water Resources Research, Volume 61, Issue 5, May 2025.
Abstract Understanding subsurface heterogeneity is crucial to predicting groundwater flow pathways, mixing, and other processes in aquifers and other fluid reservoirs. Despite significant effort developing geophysical tools to understand this heterogeneity, geophysical mapping of aquifer flow parameters—transmissivity (T) $(T)$, and storativity (S) $(S)
