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.

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%.

AVO and elastic impedance
TL;DR: In this article, a linear fit of P-wave reflection amplitude to the sine square of the angle-of-incidence (AoI) was proposed to obtain additional AVO attributes such as pseudo S-wave data and Poisson's ratio contrast.
Journal ArticleDOI
Theory of elastic constants of heterogeneous media
TL;DR: The theory of elastic equilibrium of heterogeneous, macrohomogeneous bodies is cast in the form of a linear integral equation with the following properties: (1) the equation contains a constant elastic tensor which can be chosen freely to optimize any approximation method.

Lev Vernik,D. Fisher,S. Bahret +2 more
TL;DR: In this article, the authors used both acoustic and shear impedance (AI and SI) to estimate the net-to-gross (N/G) of the Horn Mountain deepwater reservoirs, Gulf of Mexico (GOM), where six appraisal wells were available for calibration.

Seismic-wave traveltimes in random media
G. Müller,Michael Roth,M. Korn +2 more
TL;DR: In this paper, a ray-theoretical relation between the autocorrelation function of the slowness fluctuations of a random medium and the traveltime fluctuations on a profile perpendicular to the general propagation direction of an originally plane wave is established.
