The Rock Model
This topic concerns the difference between a reservoir model and a
geological model. Model representation is the essential issue - ask your-
self whether the coloured cellular graphics we see on the screen truly
resemble the reservoir as exposed in outcrop:
WYSIWYG (computing acronym) .
Our focus is on achieving a reasonable representation.
Most of the outputs from reservoir modelling are quantitative and
derive from property models, so the main purpose of a rock model is to
get the properties in the right place - to guide the spatial property
distribution in 3D.
For certain model designs, the rock model component is minimal, for
others it is essential. In all cases, the rock model should be the guiding
framework and should offer predictive capacity to a project.
