Frequency-Dependent Streaming Potential of Porous Media—Part 2: Experimental Measurement of Unconsolidated Materials
Figure 3
The calculated streaming potential coupling coefficient (normalised to the value at 5 Hz, which was 0.518 V/MPa) as a function of frequency for Ottawa sand saturated with 10−3 mol/L NaCl solution at 24°C, m2). (a) Magnitude with six models shown fitting the data [6, 9, 19, 22, 23], (b) real component for models [6, 9, 19, 23], and (c) imaginary component for models [6, 9, 19, 23].
