... as well as in forward modeling. We show, using real well log data as input into synthetic seismic modeling, that although the character of the AVO response may be not affected by the pressure-related changes in gas properties, the magnitude of this response will be definitely affected. pore fluid...

.... Since critical properties of fluid change in nanopores, we expect to see changes in the sorbed phase density for different pore sizes. The critical parameters obtained for each pore size, were then entered in Equation (8) to yield the adsorbed phase density, see Table 3 . Figure 12 demonstrates how...
