Frequency-Dependent Streaming Potential of Porous Media—Part 2: Experimental Measurement of Unconsolidated Materials
Figure 7
(a) The steady-state streaming potential coupling coefficient measured in this work shown with a compilation of silica-based earth materials measured by (open symbols) or compiled by (solid symbols) Jaafar [31, 32]. The lines represent the theoretically modelled streaming potential coupling coefficient using the method of Glover et al. [16] and Glover and Déry [17] and with the parameters sites/nm2, , , and °C, with the porosity, cementation exponent, grain size, and pH for the individual samples (given in Table 1). (b) The same diagram as (a) on an expanded scale.
