The Hodogram as an AVO Attribute
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 ...
متن کاملAn Integrated Geophysical Approach for Porosity and Facies Determination: A Case Study of Tamag Field of Niger Delta Hydrocarbon Province
Petro physics, rock physics and multi-attribute analysis have been employed in an integrated approach to delineate porosity variation across Tamag Field of Niger Delta Basin. Gamma and resistivity logs were employed to identify sand bodies and correlated across the field. Petro physical analysis was undertaken. Rock physics modelling and multi-attribute analysis were carried out. Two hydrocarbo...
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...
