Abstract
ABSTRACT
Most models for reservoir simulation are on the scale of meters to hundreds of meters. However,
increasing resolution in geological measurements results in finer geological models. Simulations of
particle movements provide an alternative to conventional reservoir simulation by allowing the
study of microscopic fluid flow, which is chosen to the scale of geological models. In this work, a
porous medium was modeled by lattice a gas automata model.
The FHP-II model (FHP: Frisch, Hasslacher and Pomeau) of lattice gas automata was developed
to simulate microscopic flow and estimate the properties of heterogeneous porous medium.
Heterogeneity simulated by places solid obstacles randomly in a two-dimensional test volume. The
properties of the porous medium were estimated by the shape, size, number of the obstacles and by
the distribution of the obstacles within the volume. Simulating of porous medium and rock
properties were varying from 10% to 35% of porosity. Numerical correlations of the porous medium
properties were found between the tortuosity, effective porosity and permeability as a function of
porosity. Reasonable agreement between the lattice gas automata simulation and theoretical results
were obtained.
Keywords: Lattice Gas Automata, porous medium, tortuosity, porosity, permeability
