Influence of the seismic attenuation on the AVO analysis in Miocene strata from Carpathian foredeep -SE Poland

Abstract

Amplitude versus offset (AVO) is one of direct hydrocarbon indications. One of the factors which can have negative influence on AVO effect is seismic wave attenuation. This paper presents how seismic attenuation distorts AVO analysis. To compensate this effect the inverse Q filter was used. Firstly, the Firstly, the evaluation of usefulness of the inverse Q filtering was verified on the model data. The promising results gave basis for the using the inverse Q filer on real data. Inverse Q application amplified intercept and gradient. After this procedure, analyzed AVO anomaly is less ambiguous.
