Abstract
Summary
Network models of porous media are a useful tool for predicting transport properties of hydrocarbon reservoir rocks. This work explores the possibility of using a reconstructed three-dimensional pore space model, obtained by means of multi-point statistical modeling based on thin images of reservoir rocks, to construct a bi-regular network model based on truncated octahedral nodes. With this model, it is possible to simulate pore systems with a wider range of pore connectivity, making the proposed model more realistic and flexible than existing cubic-based models. It is shown that using these models it is possible to accurately predict the experimentally measured permeability of the sample.
