Abstract Summary
Permeability (or hydraulic conductivity) is one of the most important parameter for analyzing hydraulic behavior of underground.This study summarizes the methods and parameters used to estimate permeability using Nuclear Magnetic Resonance signals from hydrate-bearing sediment obtained from logging and laboratory tests for the Gulf of Mexico and Alaska North Slope. In addition, we reports parameters for predicting model for muddy sediments which was recovered from overburden of hydrate-reservoir in the Hyuganada sea in 2022 Japan.
