Intrinsic wave attenuation at seismic frequencies is strongly dependent on rock permeability,
fluid properties, and saturation. However, in order to use attenuation as an attribute to extract …

We studied seismic attenuation of P-and S-waves caused by the physical mechanism of
wave-induced fluid flow at the mesoscopic scale. Stress relaxation experiments were …

Knowledge of interval attenuation can be highly beneficial in reservoir characterization and
lithology discrimination. We combine the spectral-ratio method with velocity-independent …

More than four months of continuously recorded micro-earthquake data acquired at Cold
Lake, Canada, was analyzed using advanced algorithms for microearthquake location and …

The increased drilling and production operations from unconventional reservoirs has
elevated the need for extending our understanding on their complex petrophysical, acoustic …

Such reservoir rocks as tar sands are characterized by significant attenuation and, in some
cases, attenuation anisotropy. Most existing attenuation studies are focused on plane-wave …

It is usually believed that Gassmann fluid substitution can be performed only for a fully
interconnected portion of the pore space. While this is certainly true, the presence of …

Attenuation can be extremely valuable in characterizing gas accumulations in shales and
sandstones. Laboratory studies clearly indicate that attenuation is closely related to fluid …

Source rocks possess complex heterogeneous matrices with soft organic matter, consisting
mainly of kerogen, interspersed within a stiff inorganic mineral framework that varies in …
