Since their introduction in early 1970`s seismic attributes have become one of the most commonly used and powerful interpretation tools. In earlier applications they were considered as a management display tool. This view has changed rapidly as their use in interpretation expanded. Results were analyzed in a qualitative manner. Recently, as evidenced from increasing number of papers, attribute use finally became more quantitative through calibration with well bore measurements. In this paper the authors will present a review of basic attributes, their recently introduced derivatives and their expected significance. They will also classify them with respect to their computation and their end use. They define all seismically driven parameters as the Seismic Attributes. They can be velocity, amplitude, rate of change of any of them with respect to time or space and so on. They can be computed from pre-stack or post stack data sets. Some of the attributes computed from complex traces such as envelope, phase and etc. correspond to the various measurements of the propagating wave-front. They will call those the physical Attributes. These attributes may be used for prediction or extrapolation of lithological or reservoir characteristics. Others are computed from the reflection configurations and continuity. They will call these Geometric Attributes. These are used in structural and stratigraphic interpretation. In this paper they will confine themselves to the classification and definition of the attributes and their possible uses. They will give examples from different geological settings.
