Table 4 Summary of permeability calculations for equivalent continuum models (ECMs)
Component | P10 (m−1) | Number of fractures per km2 in BBN (× 103) | Ratio of BBN fractures per km2 (andesite = 1) | Y component permeability (10–15 m2) | X component permeability (10–15 m2) |
|---|---|---|---|---|---|
Sheet-like andesite | 0.6 | 106 | 1.00 | 30.0 | 2.31 |
Ignimbrite | 0.8 | 169 | 1.59 | 47.6 | 3.66 |
Rhyolite | 1.7 | 449 | 4.23 | 126.9 | 9.77 |
