The effect of the Fresnel zone size on AVO analysis for stack data
نویسندگان
چکیده
Reflection energy from a linear reflector comes from an integrant over an aperture often described by the Fresnel zone. Within the Fresnel zone, the diffraction energy constructively builds the reflection energy. This paper uses diffraction theory to explain the reflector edge effect on amplitude and the amplitude variation within the Fresnel zone. Thus, discuss the Fresnel zone effect for AVO analysis on stack data. When the target is smaller than the Fresnel zone size or the reflection point is close to the reflector edge than the Fresnel radius, the amplitude is the result of diffraction effect on reflection. It also illustrates that AVO analysis within the Fresnel zone can be incorrect. Migration can improve it.
