Empirical relations between elastic wavespeeds and density in the Earth's crust
TL;DR: A compilation of compressional-wave (V p) and shear-wave velocities and densities for a wide variety of common lithologies is used to define new nonlinear, multivalued, and quantitative relations between these properties for the Earth's crust as mentioned in this paper.

TL;DR: A review of the current understanding of phenomena involved in gas hydrate formation and the physical properties of hydrate-bearing sediments can be found in this paper, where the magnitudes and interdependencies of these properties are critically important for predicting and quantifying macroscale responses of hydrates to changes in mechanical, thermal, or chemical boundary conditions.

The brittle-ductile transition in porous rock: A review
Teng-fong Wong,Patrick Baud +1 more
TL;DR: In this article, Bifurcation analysis can be used in conjunction with a constitutive model to predict the onset of strain localization, which is in qualitative agreement with the laboratory data.

Computation of linear elastic properties from microtomographic images: Methodology and agreement between theory and experiment
TL;DR: In this article, the elastic properties of the digitized images under dry, water-saturated, and oil -saturated conditions were derived from a suite of four samples of Fontainebleau sandstone with porosities ranging from 7.5% to 22%.

Relationships among compressional wave attenuation, porosity, clay content, and permeability in sandstones
Theodoros Klimentos,Clive McCann +1 more
TL;DR: In this paper, the attenuation coefficients of compressional waves in 42 sandstones at a confining pressure of 40 MPa (equivalent to a depth of burial of about 1.5 km) were measured using a pulse-echo method in which the sample was sandwiched between perspex buffer rods inside the high pressure rig.
Journal ArticleDOI
Synthetic microseismograms; logging in porous formations
TL;DR: In this paper, the amplitude of wave propagation in a fluid-filled porous elastic solid was analyzed for a cylindrical borehole and along a plane interface, and it was found that properties such as permeability affect the attenuation of the signal only at high frequencies.
