Determining geologic formation permeability
Techniques for determining geologic formation permeability include determining particular permeability values from an NMR log permeability data and particular permeability values of the core permeability measurements; determining a selected NMR permeability transform that includes inputs including the determined particular permeability values; minimizing a cost function to optimize the selected NMR permeability transform; calculating new permeability values for the wellbore between the terranean surface and a true vertical depth of the wellbore with the optimized NMR permeability transform; comparing the calculated new permeability values at particular depths between the terranean surface and the true vertical depth that match depths of the core permeability measurements; based on the comparison meeting a particular threshold, generating a user interface that renders one or more graphical representations of the optimized NMR permeability transform and the calculated new permeability values; and transmitting data that represents the one or more graphical representations.
