Abstract: For quantitative analysis and interpretation of the reservoir quality tight sandstone reservoirs it is essential to understand the seismic properties of low-to-intermediate porosity gas-saturated sandstones (Avseth et al., 2014). Tight sandstones have generally undergone severe mechanical and geochemical compaction processes that cause a large reduction in their original porosity from the time of their deposition. The elastic properties of low-porosity rocks depend more on the specific pore structure than on the actual porosity and, in general , the bulk modulus within the crack-like porosity dominates the overall fliud reposonse. Pore fluid effects are modelled using gassmann ( 195 1) model. It is proposed to study the variation of elastic moduli and seismic wave speeds of low to intermediate porosity sandstones using the theories mentioned above. Also a comparison between theoretical and empirical results is carried out
