Kansas Geological Survey Open-file Report 2001-38 |
Previous investigation showed the relationship between permeability and rock textural parameters including:
| Connectivity Index | An index ranging from 1 to 4 representing the degree of connection between oomolds as observed at 10X-20X |
| Packing Index | An index from 1 to 4 representing the packing density of oomolds |
| Size | An estimate of the average oomold diameter in phi units |
| Archie Matrix Porosity Index | base on Archie’s (1952) second parameter for describing matrix porosity |
| Figures below indicate that several of the parameters are correlated with permeability and that the nature of the correlation is consistent with what would be anticipated. However, nearly all are sufficiently correlated with porosity such that inclusion of these terms in a multivariate predictive equation does not significantly improve permeability prediction. |
