WebFluid flow in the longitudinal fracture is modeled by 2D fluid flow in a parallel plate. The dynamic hydraulic conductivity in the fracture is governed by two effects, i.e., diffusion and propagation, which are determined by the signal frequency, fracture aperture, and fluid viscosity. The basic theory is based on Tang and Cheng (1989). WebOptical conductivity refers to an experiment using light, such as a reflectivity measurement and then using a Kramers-Kronig transform to deduce the real part of the transverse conductivity, σ T. The transverse conductivity is measured because the direction of propagation of the photon is perpendicular to the electric field.
