Abstract
Estimating paleo-depositional cycles in a geological formation is accomplished by obtainingH nuclear magnetic resonance (NMR) measurements of restricted diffusion of a protonated fluid in a direction perpendicular to a bedding plane in a core sample aligned in the perpendicular direction and removed from the geological formation. Diffusive tortuosity is estimated from the restricted diffusion measurements, and a diffusion length at which the restricted diffusion in the core sample reaches a tortuosity limit is ascertained. An average spacing between sedimentary boundaries of restricted diffusion can then be calculated.
