The estimation method of anisotropy coefficient of shear wave velocities [PDF]

open access: yesSGEM International Multidisciplinary Scientific GeoConference EXPO Proceedings, 2018
© SGEM2018. Cross-dipole acoustic logging traditionally uses to study the anisotropy of the formation acoustic properties. The method is based on comparing the velocities of fast and slow shear waves and calculating the anisotropy coefficient. In the anisotropic formation, the flexural wave is splitting into two modes. The amplitude of cross-components

Anisotropy coefficients of a Mueller matrix

Journal of the Optical Society of America A, 2011
Anisotropy coefficients α, β, and γ that describe the type and the relative amount of the three kinds of anisotropy generally present in a Mueller matrix are introduced. Their derivation, algebraic properties, and physical interpretation are discussed.

Anisotropy in the Hall coefficient of indium

Journal of Physics F: Metal Physics, 1986
The Hall coefficient of single-crystal indium was measured in two geometries: B//(100)(RH perpendicular to ) and B//(001)(RH//) at 4.2K. An anisotropy was observed in the Kohler plot: in intermediate and low fields, RH perpendicular to is more negative than RH//. Isothermal measurements of RH at 3.5K and 1.9K are also reported. The effects of the Fermi

The anisotropy coefficient in Cerenkov counting

Applied Radiation and Isotopes, 1998
Abstract We present an improved Cerenkov standardization method, which takes into account the directional nature of the Cerenkov light. A new expression for the Cerenkov counting efficiency is derived by assuming that the generation of photoelectrons at the photocathode is described by the Poisson law.

Pore-Pressure-Coefficient Anisotropy Measurements for Intrinsic and Induced Anisotropy in Sandstone

SPE Reservoir Evaluation & Engineering, 2008
SummaryIn this study, we determine experimentally the effect of inherent and stress-induced anisotropy on stiffness components, elastic moduli, and Biot's pore-pressure coefficients (PPCs) for Lyons outcrop Colorado sandstone, which exhibits a clear transverse isotropic rock structure.

Flow fluctuations and measurement of anisotropy coefficients

Indian Journal of Physics, 2011
Recent interest in fluctuations in the anisotropy coefficients enhances the need for an accurate determination of their values. It is argued, and shown using the help of simulated data, that the measured value of anisotropy coefficients obtained using certain commonly used methods to eliminate the contribution of non-flow correlations, may also be a ...
