Optimization Of The Use Of Energy-Weighted Avo Attributes To Identify Hydrocarbon

Abstract


Amplitude Variation with Offset (AVO) is a technique that is often used as an indicator of the presence of hydrocarbons in seismic data. This technique mathematically uses an approximation to the Zoeppritz equation to identify the change in amplitude as a function of the angle of incidence and relate it to the rock properties and the fluid content in it. The energy weighted AVO attribute is very effective in identifying the presence of hydrocarbo. This is because, in principle, the energy weighted AVO attribute is to increase an anomalous response related to the presence of hydrocarbons and attenuate a seismic around the anomaly. The advantage of this attribute is that it is able to distinguish the response of hydrocarbon anomalies to other anomalies caused by lithology such as coal. In addition, this attribute is applicable to pre-stack and post-stack seismic data.
