Bulk moduli and seismic attenuation in partially saturated rocks: hysteresis of liquid bridges effect
Rozhko, Alexander (Journal article; Peer reviewed, 2019-03-20)A key task of exploration geophysics is to find relationships between seismic attributes (velocities and attenuation) and fluid properties (saturation and pore pressure). Experimental data suggests that at least three ... -
Effective fluid bulk modulus in the partially saturated rock and the amplitude dispersion effects
Rozhko, Alexander (Peer reviewed; Journal article, 2020)Frequency dispersion is a well-known effect in geophysics, which means that waves of different wavelengths propagate at different velocities. Amplitude dispersion is a less-known effect, which means that waves of different ... -
Effects of pore fluids on quasi‐static shear modulus caused by pore‐scale interfacial phenomena
Rozhko, Alexander (Peer reviewed; Journal article, 2019)It is evident from the laboratory experiments that shear moduli of different porous isotropic rocks may show softening behaviour upon saturation. The shear softening means that the shear modulus of dry samples is higher ...
