After decomposition of Prestack AVO analysis is generally performed on surface the data into separate P-and S-wave responses and data, either in the time-offset domain (see e.g.
Given an elastic inversion algorithm, basic questions become "How Traditional stratigraphic

It is far more prudent (and economical) to execute continues to be through the use of the stack section.
This study utilised a unique multioffset VSP geometry and 3-component acquisition and processing to analyze the AVO A multioffset VSP geometry and 3-component VSP response of a gas-bearing carbonate zone. Firstly, we show that processing flow have been developed to analyze the seismic the 3-component processing flow recovers the true reflection AVO response of a subsurface zone.
P-wave impedances on a scale smaller than the sampling interval (e.g. one foot), whereas a seismic AVO (Amplitude Versus Offset) analysis assumes that wavelength may be tens or hundreds of feet. Attempts to prestack seismograms contain information about elastic accurately model the target by synthetic seismograms parameters of subsurface targets, such as VpNs must account for the effects of such fine stratigraphic layering. The prestack synthetic seismogram generated contrast. In real world settings, this information is by using this kind of finely layered model with complicated by the thin bed effect of target zone.
Given that the basic wavelet shape depends only on the source and receiver Two key steps toward inferring pore fluid type location (not on the details of the raypath or lithology directly from seismic amplitudes from source to reflector to receiver), seismic are (1) "true-amplitude" or relative-amplitude traces can be decomposed into the convolutional (RAP) orocessina and (2) an effective method of effects of source, receiver, offset and earth amplitude-versu&angle (AVA) analysis.
In this technique, generalized/stochastic velocity or density) and the initial model, and inverse theory is used to determine P-wave velocity from refiection time and density is estimated using Gardner's relationship G(h) represents the differential kernel or partial derivatives (Gardner, et al., 1974). The amplitude variation with offset is with respect to each parameter of the model.

In this section we present the relevant equations governing We present a modeling scheme based on the velocity-stress the wave propagation in a fluid-filled borehole in an inhomogeneous finite-difference approximation to the elastodynamic equations formation without fractures. We then introduce the governing wave propagation in a fluid-filled borehole intersecting equations that approximate the presence of thin horizontal horizontal fractures. The model is axi-symmetric fractures.
