Abstract
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 sample with the pressure
measured by hydrophones and the streaming potential measured using silver silverchloride
electrodes. Both Packard's (1953) and Pride's (1994) models satisfactorily
predict the streaming potential behavior for these frequencies, and the measured critical
frequencies are directly related to the sample pore diameters.
