چکیده

We propose a new method for measuring velocities and polarizations of the compressional and shear waves. The method consists of measuring time dependent displacement of a particular point on the sample surface in three independent directions by a laser Doppler interferometer. The high accuracy of these measurements makes the determination of the polarization straightforward, and thus the identification the type of the waves unambiguous. These measurements can be used to estimate the stiffness tensor of anisotropic rock samples.

Preferred Orientations and Anisotropy in Shales: Callovo-oxfordian Shale (france) and Opalinus Clay (switzerland)

Anisotropy in clay-rich sedimentary rocks is receiving increasing attention. Seismic anisotropy is essential in the prospecting for petroleum deposits. Anisotropy of diffusion has become relevant for environmental contaminants, including nuclear waste. In both cases, the orientation of component minerals is a critical ingredient and, largely because of small grain size and poor crystallinity, t...

Mechanical properties of shale-gas reservoir rocks — Part 1: Static and dynamic elastic properties and anisotropy

Understanding the controls on the elastic properties of reservoir rocks is crucial for exploration and successful production from hydrocarbon reservoirs. We studied the static and dynamic elastic properties of shale gas reservoir rocks from Barnett, Haynesville, Eagle Ford, and Fort St. John shales through laboratory experiments. The elastic properties of these rocks vary significantly between ...

Resonance Ultrasound Spectroscopy for Evaluating Elastic Constants and Incohesive Bonds of Thin Films

Free-vibration-resonance frequencies of a film/substrate layered specimen depend on the dimensions, densities, and elastic constants both of the film and substrate. Then, the elastic constants of thin films are inversely determined by measuring the resonance frequencies and the other parameters. Because contributions of the film elastic constants to the resonance frequencies are small, high acc...

Compressional velocity, seismic attenuation and permeability relationships for sandstones from WOSPP

Some experimental results measuring P-wave phase velocity and seismic attenuation in laboratory under dry and water-saturated conditions at ultrasonic frequencies and atmospheric pressure on sandstone samples of the Milk River Formation in the Writingon-Stone Provincial Park (WOSPP), southern Alberta, are presented and are correlated with petrophysical data obtained from these samples as clay c...

Acoustic Double Refraction in Low-porosity Rocks by Terry Todd, Gene Simmons, and W. Scott Baldridge

Anisotropy in physical properties of rocks can arise from preferred mineral orientation, mineral layering, nonhydrostatic stress, and anisotropic crack distribution. For instance, all of the following cause acoustic double refraction: preferential orientation of olivine grains in dunites, alternating layers in laboratory-sizedsamples of such mineral pairs as olivine-feldspar, wollastonite-diops...
