| Summary: | The permeability of rock is a crucial physical parameter that indicates the rock's
ability to transmit fluids. It is influenced by the degree of connectivity between the
rock pores, which is measured by the coordination number. In this study, the
influence of coordination numbers on the permeability of three-dimensional rock
samples was analyzed. A simple 3D pore model and various types of sandstone were
used as samples in this research. The Pore Network Modeling (PNM) method was
utilized to extract 3D tomography images from sandstone rock samples and create
a pore network model to calculate the coordination number. The Lattice Boltzmann
Method (LBM) was then used to calculate the absolute permeability of the samples.
The research findings demonstrate a strong relationship between permeability and
coordination numbers in the rock samples, where larger coordination numbers
correspond to higher permeability values.
