Abstract
This invention is useful for determining the permeability of a geological formation usingH NMR diffusion measurements acquired in the laboratory and using downholeH NMR well logging. The current technology for obtaining formation permeability downhole using NMR is not adequate for low-permeability, unconventional source rock formations with high organic content. This new method uses laboratoryH NMR diffusion measurements for creating continuous downhole well logs of the mobile-hydrocarbon permeability of the hydrocarbon-filled pore space of downhole geological formations.
