Geometrical spreading compensation
Did you know?
WebCompensation for geometrical spreading is important in prestack Kirchhoff migration and in amplitude versus offset/amplitude versus angle (AVO/AVA) analysis of seismic data. We present equations for the relative geometrical spreading of reflected and transmitted P‐ and S‐wave in horizontally layered transversely isotropic media with vertical symmetry … WebABSTRACTGeometric spreading is an important factor that needs to be taken into account in the analysis of seismic amplitudes. In particular, when using any modification of amplitude variation with offset or amplitude versus azimuth methods, the effect of geometric spreading is crucial to isolate the effect of reflection from a particular interface. The …
WebOct 10, 2004 · ABSTRACT. Compensation for the geometrical spreading along the raypath is an essential step in AVO (amplitude variation with offset) analysis, in particular for wide-azimuth surveys. Here, we propose an efficient methodology to correct long-spread reflection data for the geometrical spreading in stratified azimuthally anisotropic media. … WebCompensation for geometrical spreading along a raypath is one of the key steps in AVO (amplitude-variation-with-offset) analysis, in particular, for wide-azimuth surveys. Here, …
WebDec 23, 2015 · Morozov (2008, 2010) investigated the cause of a frequency-dependent apparent Q using an improved attenuation model, and concluded that the traditional geometric spreading compensation is insufficiently accurate for attenuation measurement; consequently, the power-law frequency-dependence of Q could be falsely … WebABSTRACT In seismic data processing, compensation for geometric spreading along the raypath is necessary. The accurate approximation of the relative geometric spreading …
