Abstract
An interesting problem in the oil and gas industry is the visualization
of the movement of oil and gas in porous media. In our work we have
simulated the porous media using a pointer-based octree, representing
the distribution of pores and grains. This data structure allows us
to model the connectivity of the pores and thus visualize fluid
penetration within the media. Whereas earlier models represent a
serious simplification or two dimensional homogeneous layers, our
model provides us with a statistically accurate distribution in three
dimensions and thus a more accurate representation of the connectivity.
In this paper we present our data structure and the techniques which were
used to create models of porous media and their porous networks. Next,
we present algorithms for connectivity in octrees and we show how to
apply them to modelling and visualization of fluid penetration in
porous media.
