Abstract
ABSTRACT
This paper present a pore-network model of two immiscible fluids in petroleum industry using
lattice gas automata based on pores-and-throats representation of the heterogeneous porous media.
The network has irregular geometry and pores or capillary segments of various different shapes and
sizes distributed over the network in some irregular fashion, which is distinguishing
two-dimensional networks. The main feature of this model is the mechanisms and mobilization in
which immiscible carbon dioxide invaded the porous media occupied by oil could be simulated in
dynamic condition process.
The FHP-II (Frisch, Hasslacher and Pomeau, FHP) of lattice gas automata model is applied for
simulation of immiscible displacement process of carbon dioxide to displace oil reservoir on the
two-dimensional pore network model. The shape of the regions of displacing and displaced fluids
mechanisms was simulated. The effects of grain sizes and shapes, and its distribution that
represented by effective porosity and permeability in porous media on the displacement
mechanisms and displacement efficiency are studied. This simulation also could predict the residual
oil saturation and displacement efficiency of the processes. Comparison with laboratory experiment
was also presented. Reasonable good agreement between the lattice gas automata simulation and
laboratory experiment results were achieved.
Keywords: Lattice Gas Automata, heterogeneous porous media, oil saturation, displacement
efficiency
