One major cause of elastic wave attenuation in heterogeneous porous media is wave-
induced flow of the pore fluid between heterogeneities of various scales. It is believed that …

Computational physics has become an essential research and interpretation tool in many
fields. Particularly in reservoir geophysics, ultrasonic and seismic modeling in porous media …

Careful site characterization is critical for successful geologic storage of carbon dioxide (CO
2) because of the many physical and chemical processes impacting CO 2 movement and …

Seismic surveys successfully imaged a small scale CO 2 injection (1,600 ton) conducted in a
brine aquifer of the Frio Formation near Houston, Texas. These time-lapse borehole seismic …

Time‐lapse, three‐dimensional (3D) seismic surveys have imaged an accumulation of
injected CO2 adjacent to the Sleipner field in the North Sea basin. The changing pattern of …

Cross-property relations are useful when some rock properties can be measured more
easily than other properties. Relations between electrical conductivity and seismic velocity …

Shale source rocks are composed of various minerals, mainly smectite and illite, depending
on the burial depth, and they can be described as transversely isotropic media. The “pore …

Sedimentary rocks are often heterogeneous porous media inherently containing complex
distributions of heterogeneities (eg, fluid patches and cracks). Understanding and modeling …

Viscous attenuation can have a strong impact on seismic wave propagation, but it is rarely
taken into account in full waveform inversion (FWI). When viscoelasticity is considered in …

We undertook laboratory-based seismic measurements with dense sensor array at
ultrasonic frequencies during the injection of CO2 into a water-saturated sandstone …
