The Hodogram as an AVO Attribute
نویسنده
چکیده
INTRODUCTION The use of hodograms in interpretation of AVO cross-plots is a relatively recent innovation (Keho, 2000). Often, when comparing models of attributes to the actual seismic attributes, we find that anomalous zones are much closer to the background trend than the model indicates. One reason for this concerns wavelet effects. The AVO hodogram takes wavelet effects into account and can better isolate anomalies that are otherwise difficult to distinguish from the background trend by calculating the angle (called the polarization angle) of the hodogram for the series of points.

Amplitude versus Offset (AVO) Technique for Light Hydrocarbon Exploration: A Case Study
AVO as a known methodology is used to identify fluid type and reservoir lithology in subsurface exploration. Method discussed in this paper, consists of three stages, including: Direct modeling, Inverse modeling and Cross plot interpretation. By direct modeling we can clarify lithology or fluid dependent attributes. Analysis performed using both P-P and P-Sv attributes. Inverse modeling deals w...
متن کاملIdentification of Gas Accumulation Adjacent to the Gas Hydrate Bearing Zone by Inversion Utilizing AVO Attribute
The presence of gas hydrate and associated gas in the Makran Accretionary Prism, offshore Iran, has been confirmed by various seismic indicators, including the bottom-simulating reflector (BSR), amplitude blanking, and bright spot. The pre-stack analysis and the study of amplitude-variation-with-offset (AVO) attributes are the most reliable tools for semi-quantitative study of gas hydrate and f...
متن کاملSeismic attribute sensitivity to velocity uncertainty
This paper explores the relationship between velocity uncertainty and AVO-related seismic attributes in a dataset from the Blake Outer Ridge, offshore from Florida and Georgia. From an initial velocity model, several realizations were generated that are perturbations of the original velocity model. Prestack wave-equation migration was applied to the data for each velocity realization. In the mi...

In this article we investigate AVO effects of large offset P-wave data (up to ) and converted waves (up to ). In addition to conventional P-wave AVO attributes ( and ) a third term ( ) is examined. For P to S converted waves we introduce two AVO attributes and . Background trends for certain cross plots are related to rock property relationships. These new attributes are used to discriminate co...
