core permeability correction to log scale using multiple linear regression with logarithmic transformation

Heterogeneity is the spatial variability in permeability and can be calculated by two methods: 1-Dykstra-Parson Coefficient 2-Lorentz Coefficient #1-Dykstra-Parson Coefficient This methods implies simple calculations on permeability values in a table form. It starts with calculating the number of data points with greater or equal permeability (Number of samples >=k). This can be used in further calculation of the samples portion (%>=k). Then, when plotting the latter against permeability in log-normal distribution, a straight trend line should be observed. Finally, we can model the relationship and calculate the heterogeneity index (HI) through mathematical formula. Heterogeneity index
