Aimed target area is deeply buried, complex lithology, dual media, reservoir development degree controlled by a variety of factors, meanwhile, lateral thickness and lithofacies change rapidly, strata formation poor. Therefore, igneous rock has difficulty in predicting, since seismic complicated to track trace, attribute analysis hard determine the time window, inversion modeling requires sophis...

Seismic data are used in petroleum exploration to define geologic features in the subsurface. Recent advancements in seismic exploration have examined the effect of fluid and rock properties on seismic attributes. These advancements may provide improved reservoir characterization using techniques examined here. This is accomplished two parts; first, a study of fluid properties and their effect ...

Offset-dependent characteristics of seismic scattering are useful in the interpretation of fractured reservoirs. Synthetic seismograms generated by a 3-D finite difference modeling are used to study elastic wave propagation and scattering in heterogeneous fraetmed reservoirs. We use two models having different background medium properties and different azimuthal AVO responses and build heteroge...

Reservoir characterization has a leading role in the reservoir geophysics and reservoir management. Since the interests of the reservoir geophysics and reservoir managements are the elastic properties and reservoir properties of the subsurface rock for their purposes, a robust method is required for converting seismic data into elastic properties. Accordingly, by employing a rock physics model ...
