Abstract
The complex resistivity of coal and related rocks contains abundant physical property information, which can be
indirectly used to study the lithology and microstructure of these materials. These aspects are closely related to the
fluids inside the considered coal rocks, such as gas, water and coalbed methane. In the present analysis, considering different lithological structures, and using the Cole-Cole model, a forward simulation method is used to study
different physical parameters such as the zero-frequency resistivity, the polarizability, the relaxation time, and the
frequency correlation coefficient. Moreover, using a least square technique, a complex resistivity “inversion” algorithm is written. The comparison of the initial model parameters and those obtained after inversion is used to
verify the stability and accuracy of such approach. The method is finally applied to primary-structure coal considered as the experimental sample for complex resistivity measurements.
