WebThe rock physics modeling revealed that as the gas saturation varies, P-wave velocity dispersion and attenuation occurs at seismic frequencies, and it tends to move to high frequencies as the gas saturation increases. Web5 de abr. de 2024 · Seismic amplitudes can be inverted for the constitutive rock properties on a small distance scale but are unable to recover long-distance trends in those properties. Inversion of gravity data for density has an opposite complementary behaviour. In that sense, the two measurements are sensitive to different bandwidths of the same rock …
