Why use <strong>SBED</strong>?<br />
Core plug data: Tilje 3A Formation<br />
Question:<br />
Can we derive petrophysical properties from<br />
these data (core plugs) that are representative at<br />
the grid-cell scale <strong>of</strong> a reservoir model ?<br />
Problems:<br />
Kv and Kh are NOT well characterized by core<br />
plugs or wirel<strong>in</strong>e data.<br />
Permeability data me<strong>as</strong>ured from core plugs that<br />
have a sample volume below the REV will be<br />
unrepresentative.<br />
There<strong>for</strong>e we see extreme variability <strong>of</strong> plug<br />
permeabilities (Kv, Kh) even <strong>in</strong>side small vertical<br />
<strong>in</strong>tervals.<br />
Answer:<br />
No! But us<strong>in</strong>g <strong>SBED</strong> to model the heterogeneity<br />
at a more suitable volume (REV) and us<strong>in</strong>g flowb<strong>as</strong>ed<br />
upscal<strong>in</strong>g to determ<strong>in</strong>e properties could<br />
be a more realistic solution…<br />
Th<strong>in</strong> <strong>in</strong>tercalations <strong>of</strong> mudstone and<br />
sandstone layers will have a strong <strong>in</strong>fluence<br />
on the flow properties!
