In this study we integrate Previous HitseismicNext Hit attribute data with results from Previous HitseismicNext Hit sedimentological and geomorphological studies of an extensive 2D survey. Aim of the study is to outline an approach for the use of volume based Previous HitseismicNext Hit Previous HitattributesNext Hit for automated Previous HitseismicNext Hit facies mapping within a carbonate setting. The study area used for that approach is located in the central Persian Gulf, offshore Iran. The interval of interest is the mid-Cretaceous Sarvak Formation, which is part of the extensive Cretaceous shallow water carbonate platform of the eastern Arabian Plate.

A set of 9 volume based Previous HitattributesNext Hit calculated from time, amplitude and frequency information of the post-stacked Previous HitseismicNext Hit data, was defined in order to describe geological information within the interval of interest. Calculated Previous HitattributesNext Hit include the integrated Previous HitseismicNext Hit amplitude, integrated instantaneous frequency, integrated cosine of phase, integrated apparent polarity and integrated reflection strength. These volume based Previous HitattributesNext Hit were supplemented by the grid based Previous HitattributesNext Hit ‘dip' and ‘azimuth' in order to highlight structural elements. The geological significance of each attribute was examined by comparing it with results of Previous HitseismicNext Hit sedimentological/geomorphological studies. Furthermore, statistical methods were applied to highlight direct relations of the Previous HitattributesNext Hit to each other. The results of these tests were than used to choose limited sets of Previous HitattributesNext Hit for neural network based classification runs, both unsupported as well as supported by training data from the Previous HitseismicNext Hit data set. The result show that Previous HitseismicNext Hit Previous HitattributesNext Hit derived from 2D surveys can be used to automatically map basic Previous HitseismicTop facies types in carbonate settings.
