Web4 apr. 2024 · Geosynthetic clay liner (GCL) is commonly used in cover system of engineered landfill to limit migration of gases and infiltration of water. In … 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).
Gas hydrate accumulation and saturations estimated from …
Web5 dec. 2024 · Using this characteristic, we can determine the hydrate saturation by combining the porosity obtained from density logging and NMR logging. The calculation formula is as follows: (1) where Sh is the hydrate saturation, while and are the density porosity and nuclear magnetic porosity, respectively. WebFrom a geophysical remote sensing perspective, such co-existing gas could cause errors in hydrate saturation estimates from electrical resistivity as both gas and hydrate are … ewheels mobility
