Methods for performing formation evaluation and related systems

A method comprising:

• injecting a sinusoidal wave current into a formation sample;
• measuring a voltage signal response;
• identifying phase shifts between the sinusoidal wave current and the voltage signal response as the frequency-dependent resistivity;
• deriving a complex conductivity spectrum from the frequency-dependent resistivity;
• and
• physically measuring a physical property of non-ionic conductor grains (c-grains) in the formation sample;
• and
• correlating the complex conductivity spectrum to the physical property of the c-grains.

A method for performing formation evaluation of a formation and/or formation's surrounding, the method comprising:

• (a) providing at least one borehole;
• (b) measuring a conductivity for the formation's surrounding using a borehole device in a borehole over a plurality of frequencies to produce a complex conductivity spectrum;
• (c) collecting the complex conductivity spectrum over a detection volume;
• (d) applying at least one inversion technique to the complex conductivity spectrum to produce an inversion result;
• and
• (e) identifying a physical property of non-ionic conductor grains (c-grains) in the detection volume based on the inversion result.
