Laboratory Study of Frequency Dependent Streaming Potentials
Frequency dependent streaming potentials were measured on a glass capillary, porous filter, and a sample of Boise sandstone. The pore diameters for these three samples range from 1 millimeter to 34 micrometers. The frequencies used in these experiments range from 0-600 Hz with the critical frequencies being 6.8 Hz, 90 Hz, and 400 Hz for the three specimens. The fluid was moved relative to the s...
متن کاملFrequency-Dependent Streaming Potentials.
An experimental apparatus and data acquisition system was constructed to measure the streaming potential coupling coefficients as a function of frequency. The purpose of the experiments was to measure, for the first time, the real and imaginary portion of streaming potentials. In addition, the measured frequency range was extended beyond any previous measurements. Frequency-dependent streaming ...
متن کاملFrequency-dependent streaming potentials: a review
The interpretation of seismoelectric observations involves the dynamic electrokinetic coupling , which is related to the streaming potential coefficient. We describe the different models of the frequency-dependent streaming potential, mainly the Packard's and the Pride's model. We compare the transition frequency separating low-frequency viscous flow and high-frequency inertial flow, for dynami...
متن کاملTwo Phase Streaming Potentials
The streaming potentials generated by the flow of both liquid and gas through either a Pyrex capillary tube or else an unconsolidated Pyrex porous medium were investigated. This mixture of distilled water plus nitrogen gas simulated wet steam but allowed experiments to be run at room temperature. Single-phase flow of distilled water alone resulted in a constant voltage-to-pressure drop ratio, W...
متن کاملInteraction Potentials of Hg-Ar from Temperature Dependent Absorption Spectra
The temperature dependence of the absorption spectrum k(v) of Hg-Ar-mixtures in the range 30—1000 cm-1 about the center of the Hg-line a t vq = 39425 cm-1 (Ao = 2536.5 Ä) has been investigated in the temperature interval 473 —1273 K. The measurements were carried out at number densities 1.0 x 1017—9.1 X 1018 cm-3 for Hg and 9.4 x 1018—9.7 x 1018 cm-3 for Ar. Potentials for the Hg-Ar-system in t...
