Seismic Attributes for Reservoir Property Prediction - A Review

Abstract

Seismic attributes are extensively used in prediction of reservoir property, such as morphology Properties and petrophysical properties of the reservoir. There is no direct relation exist between most of the calculated attributes and the measured reservoir property but still we can use these seismic attributes by statistically correlating them with the measured reservoir property at the well location. In this paper we will review the correlation of some of the important properties of the reservoir with the seismic attributes and how these attribute should be used to predict the reservoir desired property of investigation. We will describe how to select the different attributes to produce a meta-attribute (hybrid attribute) and how to use THESE META-ATTRIBUTES to map the reservoir property. We will discuss how other branches of geophysics (AVO, Rock-Physics) help us in more reliable reservoir property prediction.
