WebIt should be noted that gas hydrate saturation is the measurement of the percentage of pore space in a sediment occupied by gas hydrate, which is the mathematical complement of Archie-derived water saturations (see Collett and Ladd, 2000). WebGas hydrate saturation obtained by the EMT is higher than that of the Archie equation because the Archie equation ignores the influence of clay conductivity and low porosity (Li et al. 2024b). The EMT is based on well-established physical principles and mathematical models (Berg 1996).
