Spectral estimation, and corresponding time‐frequency representation for nonstationary
signals, is a cornerstone in geophysical signal processing and interpretation. The last 10–15 …

The finite element method is used to solve Biot's equations of consolidation in the
displacement‐pressure (u− p) formulation. We compute one‐dimensional (1‐D) and two …

Reservoir monitoring is one of the key factors in the management of oil and gas resources.
In particular, the evaluation of the Enhanced Oil Recovery (EOR) method through reservoir …

The deformations caused by an acoustic wavefield in subsurface rock can induce fluid flow
within hydraulically interconnected mesoscopic fractures, from one fracture into the other …

Hydraulic fracturing treatments are often monitored by strings of geophones deployed in
boreholes. Instead of picking discrete events only, we here use time‐frequency …

Oscillatory seismic signals arising from resonant vibrations of hydraulic fractures are
observed in many geologic systems, including volcanoes, glaciers and ice sheets, and …

Fluid-filled fractures support guided waves known as Krauklis waves. The resonance of
Krauklis waves within fractures occurs at specific frequencies; these frequencies, and the …

Krauklis waves are a special wave mode that is bound to and propagates along fluid-filled
fractures. They can repeatedly propagate back and forth along a fracture and eventually fall …

The transition from recoverable elastic to permanent inelastic deformation is marked by the
onset of fracturing in the brittle field. Detection of this transition in materials is crucial to …

Modeling of Resistivity and Acoustic Borehole Logging Measurements Using Finite Element
Methods provides a comprehensive review of different resistivity and sonic logging …
