Summary<br />
• In tidal heterolithic facies (e.g. Tilje Fm.) it is difficult to determ<strong>in</strong>e<br />
representative <strong>permeability</strong> values us<strong>in</strong>g conventional core plugs<br />
• <strong>SBED</strong> method w<strong>as</strong> used to generate log-scale <strong>permeability</strong> b<strong>as</strong>ed on<br />
process b<strong>as</strong>ed model<strong>in</strong>g <strong>of</strong> small-scale geology (bedd<strong>in</strong>g scale)<br />
• Mov<strong>in</strong>g w<strong>in</strong>dow upscall<strong>in</strong>g enabled Kh and Kv values to be generated at<br />
the log scale (ca. 12,5 cm), consistent with other wirel<strong>in</strong>e data<br />
• Kh and Kv logs from <strong>SBED</strong> can be used <strong>as</strong> “tra<strong>in</strong><strong>in</strong>g” data <strong>for</strong><br />
<strong>permeability</strong> and facies prediction <strong>in</strong> non-cored wells<br />
- E.g. Us<strong>in</strong>g the NNI method <strong>in</strong> Paradigm Facimage<br />
• <strong>SBED</strong>/Facimage can provide a more realistic (Kh and Kv) and consistent<br />
data <strong>in</strong>put to the geo-model (RMS)<br />
- All <strong>in</strong>put data with a similar sample volume<br />
- Bedd<strong>in</strong>g scale, but not necessarily representative at the grid block !<br />
- Additional <strong>modell<strong>in</strong>g</strong> and upscal<strong>in</strong>g step may be necessary
