2. Are your rock properties estimated at the

REV?
• Hint: Try to relate your model length
scales (grid sizes) to the natural rock archi-
tecture length scales using the multi-scale
REV sketch.
3. What length scale has the largest influence on
the flow process?
• Hint: Some flow processes ignore small-
scale variations while other flow processes
may be are strongly controlled by them.
Use Flora's rule (Fig. 2.15 ) .
4. Are your flow forecasts based on single-phase
or multi-phase flow equations using represen-
tative rock properties and appropriate fluid
properties.
• Hint: What really controls your flow pro-
cess - k effective ,k fracture ,k relative ,k v or P c .
Are you reasonably happy with your
assumptions? Press 'execute' on the simulator
and review the outcomes.
