Frequency Dependent Electrokinetic Studies of Rocks and Soils.

Abstract

An experimental apparatus and data acquisition system was constructed to acquire frequency dependent streaming potential coupling coefficient information. The purpose of the experiments was to validate the frequency dependent theories of Pride and Packard. Frequency dependent streaming potential experiments were conducted on one glass capillary and two porous filters. Results indicated that both Packard's and Pride's models can fit the data. Experimentation continued on rocks. The new database and/or models can be used in seismoelectric models/interpretation and allow for the direct in situ determination of permeability. As a direct outcome of the research, a joint USAF/MIT patent disclosure was filed.
